Self-Retracting Lifelines | Inspection Checklist

Self-Retracting Lifelines | Inspection Checklist

Not keeping up with inspections and maintenance can cause equipment failure, unscheduled outages, increase business cost and most importantly, can have a major effect on your workplace safety.

Self-retracting lifelines (SRL) must be inspected before each use, annually inspected by a competent person and recertified every five years.

When it comes to fall protection, you must be sure your equipment is up to the job. The reality is, when working at heights, workers are depending on equipment like SRLs to ensure they can return home to their family. You never know when an accident may take place, and when it does, you want to be connected to an SRL that is up on its inspection and ready to do its job!

Who should inspect SRLs?

Daily inspections should be performed by trained employees before beginning the workday. It can be helpful to do inspections alongside other co-workers, so that way if something of concern is found, you have the opportunity for a second set of eyes to look at it. However, if anything does look concerning, always turn to certification experts. The checklist and tips to follow in this blog will cover how to best perform these daily inspections.

Mandatory annual inspections are only to be performed by a trained and competent or designated person. Hercules SLR has qualified technicians to inspect and repair your securing, lifting and rigging equipment on-site or in one of our full service, rigging shops. Our experienced and LEEA certified team will ensure that your equipment complies with provincial regulations. Once inspections, repairs, and testing is complete, we will supply full certification on your equipment to show that it complies with provincial and national safety regulations.

SRL Inspection Checklist

Before you begin, it’s important to always inspect and operate the SRL in a mounted position – do not pull the cable out of the housing or let it retract while the unit is lying flat. As you go through these steps, the SRL fails anything mentioned, it must be removed from service immediately.

  • Visually Inspect the external housing or cover for any cracks or damage. The housing is not removable and will require special tools open – DO NOT open the unit unless you have been authorized and trained.
  • Ensure you can read the label including the date of manufacture, serial number, manufacture information, and warnings. If you can not read this information, you must remove it from service.
  • FOR WIRE ROPE SRLs – Using a glove to protect your hand, slowly pull the cable from the housing looking for cuts, frayed areas, worn or broken strands, rust, pitting corrosion or deterioration. Also look for any misshapenness in the rope including things like crushed, jammed, or flattened stands, kinks, bulges in the cable, gaps between the strands, or heat damage.
  • FOR WEB SRLs – Slowly pull the webbing from the housing look for holes, tares, abrasions, discoloration, or fraying of the webbing. Make sure you look at both sides and pull on the webbing to visually confirm there are no holes or tears.
  • FOR WEB SRLsBend the webbing to make an inverted “u” shape so you can get a better view of the surface. Look for any shiny spots, loose stitching or broken fibers.
  • FOR WEB SRLsRub the surface of the sling using a bare hand feeling for any hardened spots as this could be a sign of heat damage.
  • Ensure there is a wear pad in place.
  • Check the carabiner ensuring there are no cracks, bends in the metal, discoloration, and make sure the lock is functioning properly. You can test this by opening and closing the carabiner to make sure it locks into place on its own and doesn’t get caught.
  • Perform a retraction and tension test by pulling out 50% of the lifeline, and then allow it to slowly retract retaining a light tension on the cord (do not let it go). Check to make sure the lifeline can retract smoothly. Then repeat this, pulling out the full lifeline. It is important to maintain a light tension on the lifeline at all times during this test as a bird’s nest could be formed within the housing if it retracts too fast.
  • Test the brakes by grasping the lifeline and apply a sharp and steady pull downwards until the breaks engage, and then keep tension on the lifeline until the breaks are fully engaged. There should be no slipping felt during this process. Again, allow it to retract keeping light tension. The brakes should release and allow the lifeline to retract smoothly back into the housing. Repeat this several times at different length points.

5 Top Tips | Caring for Wire Rope

5 Top Tips | Caring for Wire Rope

Rigging equipment has a tough job lifting and moving heavy loads for hours and hours a day. In order for that equipment to be able to be its job, we have to take proper care of it. We expect longevity and endurance from equipment like wire rope, but that can easily turn if not properly treated. Equipment that is properly treated, handled, installed, inspected and stored will reward us with a prolonged life of service, better job performance and peace of mind in knowing it won’t fail.

Riggers don’t have the luxury of simple equipment slip-ups. If your rigging equipment fails you, it can cause damage to product, property and worst-case scenario, an extreme safety hazard resulting in injury or loss of life. Since wire rope is a material of choice in heavier lifts, extreme safety hazards can be a real possibility if you’re using rope that’s in an unsafe condition.

But that can be avoided! Here are 5 top tips to help you keep you wire rope in tip-top condition…

1. Seizing Your Wire Rope

Seizing and cutting operations are not difficult to perform, but are crucial in the performance of wire rope. Proper seizing must be applied to both rope ends to protect the wire ropes from loosening – Carelessly or inadequately seized ends may cause distortion or flattening of the rope. If you use wire rope that is not properly seized it will cause uneven distribution of the load over the strands causing the life of the wire rope to be drastically shortened.

Normally, one of two methods are used to do this. Typically method one is suitable for wire ropes with a diameter over one inch, and method two is those with a diameter one inch and under.

Method One:

  1. One end of the seizing wire is placed between the valleys of two strands.
  2. Turn another end around the rope and the fixed end of seizing wire closely and tightly at right angles.
  3. Stop turning after the proper length of seizing has been applied.
  4. Twist two ends of seizing wire together and make sure they are seizing the rope tightly.

Method Two:

  1. Wrap with small wires as shown in the picture.
  2. Twist the two ends of seizing wire together.
  3. Alternatively tight twist with end cutters.

2. Care When Unloading & Handling

If you’re dealing with loading or unloading wire rope in a reel or coil, it’s important to know that that is not a protected storage method and if you drop the reel during this process, it can lead to serious damage to your wire rope. Because of this, it is important to handle reels of wire rope with care and focus not to drop or damage the reel. Damage to the reel can also make it incredibly difficult to remove the wire rope from the reel, so it’s not only an important safety precaution but will also save you time and frustration in the future.

It’s also important to take care when removing wire rope from the reels or coils. When doing this, ensure the reel or coil is rotating as the wire rope unwinds. Below you will see some of the rights vs. wrongs for unwinding rope.

3. Installation By Trained Professionals

In the rigging field, it’s very important that workers be properly trained in any and all tasks they are performing because many lifts can become extremely dangerous if even one aspect is done incorrectly. So the most important thing to take away from this tip is to seek out proper training from certified professionals before taking on tasks like installing wire rope!

Once you have that training you will know how important it is to take into account the design factor of any equipment being used with wire rope, being sure to take note of the nominal diameter of wire rope to use with the equipment, as specified by the manufacturer. Installing an incorrect size will result in a failed rope or shorter service life as the rope can get pinched into a smaller space compromising its integrity.

Wire rope diameter is determined by measuring the outer circle of the strands, which is the greatest dimension that can be measured with a pair of parallel-jawed calipers or machinist’s caliper square. You can easily make a mistake if not taking care in measuring the largest dimension, as shown below:

 

4. Keeping up with Inspections and Assessments

Keeping up with the required inspections is something that must be prioritized for all rigging equipment. Wire rope is often used for heavy lifting, which means they are being used in situations where they are trusted to keep not just your load safe, but the people and the environment around it. That means that you have to be confident that your wire rope is up to the task – And how do you do that? Inspections!

Based on manufacturer/organization recommendations, ensure your wire rope is being inspected by a certified professional where the rope can be dismantled and tested through visual assessment and non-destructive testing. Hercules SLR can make this a worry-free part of your business – Our experience and LEEA certified team can take this completely off your hands, on-site or in our fell service rigging shops! 

On top of these professional inspections, wire rope should also be visually assessed by trained and experienced workers at the start of every shift or when resuming stalled work. Thorough visual assessments should also be carried out after reattaching or refitting the wire rope on the same or different equipment. Machine operators should be trained to visually assess the entire wire rope, with emphasis on points of attachment.

Things to look for when visually assessing a wire rope:

  • Broken Strands –  One of the easiest ways to do this is to run a cotton cloth over the length of the wire (if possible), checking for any places where the material get’s snagged. Any cable that has a single broken wire strand located around critical fatigue areas (where the cable runs around a pulley, sleeve or through a fair-lead; or any section where the cable is flexed, rubbed, or worked) must be replaced. Generally, SOME broken wires in non-critical areas are okay, but always consult your service/maintenance manual.
  • Surface Wear and Tare – Look out for any flat spots, any areas where the cable twist is unraveling, or any other condition resulting in the cable being distorted—If any of these things are present, you must replace the cable.
  • Internal Ware and Tare –  It is recommended to remove the cable whenever possible and flex them to ensure that all cables on the inside of the wire rope haven’t worn down due to environmental deterioration, distortion or fatigue. If you haven’t been keeping up with regular inspections, this is particularly necessary as it is possible for wire rope to look completely sound from the outside, but as soon as you move it around, it completely fails.

5. Proper Storage Methods

Wire rope needs to be stored in a well-ventilated, dry, and covered area and should not come in contact with the floor. If it is necessary to store it outside, they must be covered so that moisture cannot get inside and cause corrosion. You should also make sure that they are protected from dust, water, steam, salt, chemical fumes or adverse climatic conditions.

Turning the reel occasionally is a good practice to get in the habit of. This will prevent the wire rope’s lubricant from wearing off. If ropes are stored for a long time, it is advised for you to get them examined periodically and apply a coat of lubricant to them.

Bonus tip: If you live in an area that is prone to termites, protect the wooden reel by storing it on cement flooring.

National Space Day | Rigging in Space

National Space Day | Rigging in Space

Did you know that today, May 1st, is national space day? We here at Hercules Group of Companies wanted to participate in the fun spirit of today by having a look at some of the ways rigging and fall protection equipment is used in outer space!

Yes, you heard us right – Rigging is essential in many different sectors, and space exploration is included on that list, how cool?! Check out these 5 ways rigging and fall protection equipment like wire rope, harnesses and shackles make space exploration possible:

1. Specially Designed Steel Rope Riser Cables – Orion Spacecraft

NASA’s Orion spacecraft is built to take humans farther than they’ve ever gone before. Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel, and provide safe re-entry from deep space return velocities.

In order for the Orion spacecraft to safety return to Earth, it relies on it’s parachute – a parachute that’s equipped with specially designed steel rope riser cables! in 2014, NASA conducted a test flight for the Orion Space Capsule where after making two orbits of the Earth, it reentered the atmosphere and was brought to a successful splashdown in the Pacific Ocean.

 

2. Cicoil engineered Biomedical Harness – Apollo 11

When Neil Armstrong took his historic first step on the surface of the Moon, he was wearing a bio-belt that was fitted with a Cicoil engineered Biomedical Harness. This harness took the typical safety measures of a lead and harness and kicked it up a notch, with special biotelemetry technology that allowed for tracking vital signs of the astronauts, such as heart rate, blood pressure, respiration, body temperature, and pulse rate to be recorded and evaluated.

Since at the time they were uncertain of the effects on the human body associated with Space flight, this elevated harness allowed for surgeons at the Ground Command Center in Houston to identify problems in real-time and provide quick solutions. Without this important piece of what we like to think of as EXTREMELY elevated fall protection, who can say that the Moon landing expedition would have been possible.

 

3. Exercise Countermeasures – ISS

The human body goes through a lot when going into space, and negative effects on the body can be associated with long periods spent in space. NASA uses exercise countermeasures on the International Space Station (ISS) in order to maintain their crew’s health and combat these negative effects. Most of these countermeasure exercise systems rely heavily on textile and wire rope as well as fall protection style systems and harnesses.

There are many different specially designed exercise machines used in space. If you’re interested in learning a bit more about these, click here for some examples! In the photo here you see an astronaut using a specially designed version of a treadmill, strapped in using a lead and harness to allow him to complete his workout without floating away!

 

4. PBI Fiber Rope Sleep Restraint – Apollo 11

Looking at another example from the famous Apollo 11, sleep restraints were made out 10-foot PBI (polybenzimidazole) fiber rope with plastic ferrules on the ends to prevent fraying. Sleeping bags were latched to the center aisle of sleeping quarters using this special rope. This is a system that at its core is still in place in modern space exploration, but has of course been updated.

The photo featured here is one of the five ropes flown on the Apollo 11 mission to the Moon. These were transferred to the Smithsonian in 1970 as important aspects of history being made in space exploration!

Herc How-To | Chain Sling Inspection Checklist

Chain Sling Inspection Checklist

Not keeping up with inspections and maintenance can cause equipment failure, unscheduled outages, increase business cost and most importantly, can have a major effect on your workplace safety.

In Canada, the rigging industry recognizes the American Society of Mechanical Engineers (ASME) standards for securing, rigging and lifting industries. Standard ASME B30.9 applies to wire rope slings, chain slings, web slings or synthetic slings and round slings.

In-between those required inspections, it’s always a good idea to be proactive about your workplace safety and perform pre-operation inspections. Below are some tips to keep in mind to ensure your required annual (or otherwise) inspections are being kept up with, and you’re equipped with the knowledge necessary to ensure they are safe in-between.

Who should inspect chain slings?

A chain sling should only be inspected by a trained and competent or designated person. Hercules SLR has qualified technicians to inspect and repair your securing, lifting and rigging equipment on-site or in one of our full service, rigging shops. Our experienced and LEEA certified team will ensure that your equipment complies with ASME and provincial regulations. Once inspections, repairs and testing is complete, we will supply full certification on your equipment to show that it complies with provincial and national safety regulations.

When should you inspect chain slings?

A thorough examination, including chain usage, should be carried out by a competent person at least every year or more frequently according to statutory regulations, type of use and past records. If slings are being used in extreme conditions, The Centre for Occupational Health and Safety (CCOHS) recommends they be inspected every 3 months instead of the standard once per year. Inspections must be recorded.

Contact us to learn more!

Chain Sling Inspection Checklist

The CCOHS recommends the following steps to properly inspect a chain sling. These are steps that can be referenced when performing daily checks before putting your chain sling to use – But leave the scheduled annual (or monthly) inspections to the trained professionals!

Follow along with our checklist here, or download our printable version to have on hand at your workplace. You’ll find other engaging, practical resources on topics ranging from rigging, warehouse safety, fall protection, personal protective equipment, transportation and more by checking out our full list of toolbox topics.

  • Clean the chain sling before beginning the inspection
  • Check the identification tag to ensure it is legible.
  • Hang the chain sling up or stretch the chain out on a level floor in a well-lighted area. Remove all the twists then measure the sling length to ensure it hasn’t been stretched.
  • Perform a link-by-link inspection of the chain, master link, loads pins, and hooks observing for the following:
  • Observe overall wear, discard if this exceeds 15% of a link diameter.
  • Note any surface damage, discard of you find any cuts, nicks, cracks, gouges, burns (or evidence of heat damage), weld splatters or corrosion pits.
  • Ensure no individual links are closed up or stretched longer and that all links are able to hinge (articulate) freely.
  • Ensure hooks have not been opened more than 15% of the normal throat opening, measured at the narrowest point, or twisted more than 10° from the plane of the unbent hook.
  • Manufacturers’ reference charts show sling and hitch capacities. Record manufacturer, type, load limit, and inspection dates.

 

If you find any of the above-mentioned defaults, remove the chain sling from service immediately. If you see something presenting that’s causing doubt as to the safety of your chain sling, even if it’s not featured on this list, ask the experts! It’s always better to be safe than sorry.

Also note: Slings must be repaired by the sling manufacturer, or a qualified person, per ASME B30.9.

BONUS TIPS: The Dos and Don’ts of Using Chain Slings Safely

Staying on top of mandatory inspections for your chain sling is the best way to ensure it’s up to the task. However, a piece of equipment is only as good as the person using it! Using rigging equipment properly is very important, so proper training is key.

Below are some quick dos and don’ts to keep in mind when using a chain sling. But remember, this does not replace a training course!

Do

  • Always know how to properly use the equipment, slinging procedures before attempting the lift operation. Don’t have that knowledge? Train with the best at the Hercules Training Academy.
  • Inspect the slings and accessories before use for any defects.
  • Replace broken safety latches.
  • Find out the working load limit (WLL) before lifting. Do not exceed the rated load of the sling.
  • Ensure chain slings fit freely – Never force, hammer, or wedge chain slings or fitting into position.
  • Always keep your hands and fingers from between the load and chain when tensioning slings or when landings loads.
  • Ensure the load is free to be lifted.
  • Perform a trial lift and trial lower to ensure the load is balanced, stable and secure.
  • Balance the load to avoid overstress on one sling arm or the load slipping free.
  • Lower the working load limit if severe impact may occur.
  • Pad sharp corners to prevent bending links and to protect the load.
  • Position hooks of multi-leg slings facing outward from the load.
  • Reduce the load limit when using chain slings in temperatures above 425°C (800°F).
  • Store chain sling arms on racks in assigned areas and not lying on the ground. The storage area should be dry, clean and free of any contaminants which may harm the sling.

Don’t

  • Avoid impact loading: do not jerk the load when lifting or lowering the sling. This motion increases the actual stress on the sling.
  • Do not allow access to the lifting area to unnecessary personal.
  • Do not leave suspended loads unattended.
  • Do not drag chains over floors or attempt to drag a trapped sling from under a load. Do not use a sling to drag a load.
  • Do not use worn-out or damaged slings.
  • Do not lift on the point of the hook.
  • Do not overload or shock load a sling.
  • Do not trap slings when landing the load.
  • Do not splice a chain by inserting a bolt between two links.
  • Do not shorten a chain with knots or by twisting other than by means of an integral chain clutch.
  • Do not force or hammer hooks into place.
  • Do not use homemade connections. Use only attachments designed for the chain.
  • Do not heat treat or weld chain links: the lifting capacity will be reduced drastically.
  • Do not expose chain links to chemicals without the manufacturer’s approval.
  • Do not stand in line with or next to the leg(s) of the sling that is under tension.
  • Do not stand or pass under a suspended load.
  • Do not ride on sling.

Without inspections and maintenance, equipment failures can have a major effect on business costs, cause unscheduled outages and most importantly, could cause major and possibly deadly safety hazards. Hercules SLR offers LEEA-certified inspections, repairs, predictive & preventive maintenance (so you can pass those inspections!) and parts & accessories like wire rope slings, hoists & whatever else you need to lift.

Product Spotlight | Crosby Shackles

Product Spotlight | Crosby Shackles

Crosby is one of the most recognizable names in the rigging industry, and has been for over 100 years. Crosby makes over 2,000 rigging and lifting products to meet all your hoisting needs, and Hercules SLR is proud to be an Authorized Crosby Distributor and a Certified Crosby Repair Center.

Focusing today on Crosby shackles, as Crosby says, “there is no equal”. When you buy Crosby, you’re getting some attributes that are guaranteed when you buy their rigging and lifting equipment. The attributes that make Crosby shackles stand out from the rest include:

  • Design – Crosby carbon shackles have the highest design factor (6 to 1) in the industry. Crosby purchases only special bar forging quality steel with cleanliness and guaranteed hardenability. All material chemistry is independently verified prior to manufacturing to assure that strength, ductility and fatigue properties are met.
  • Closed Forged – Each shackle is closed die forged which allows for an increased cross-section that, when coupled with quenched and tempering, enhances strength and ductility. Close tolerance holes and concentric pins with good surface finishes are provided by Crosby and are proven to provide improved fatigue life in actual use. Crosby shackles are fatigue rated as well as load rated.
  • Quenched and Tempered – All Crosby shackle bows and pins are quenched and tempered, which enhances their performance under cold temperatures and adverse field conditions. Crosby’s Quenched and Tempered shackles provide the tensile strength, ductility, impact and fatigue properties that are essential if they are to perform time after time in adverse conditions. These properties assure that the inspection criteria set forth by ANSI will effectively monitor the ability of the shackles to continue in service.
  • Identification and Application Information – Crosby forges “Crosby” or “CG”, the Working Load Limit, and the Product Identification Code (PIC) into each bow and “Crosby” or “CG”, and the Product Identification Code (PIC) into each pin of its full line of screw pin, round pin, and bolt type
    anchor and chain shackles.

Crosby creates a variety of different shackles ranging in size, type, class, capacity and more to exceed the toughest demands of any industry, including land-based and offshore energy, construction and infrastructure, cargo handling and towing, marine, mining, and transportation. Below we take a bit of a closer look into a few of the key shackles in Crosby’s extensive library – But if you aren’t seeing something you’d like to know a bit more about, reach out! Our experts are always happy to help.

Anchor Shackles

An anchor shackle can be identified by it’s larger round “O” shaped bow. They are sometimes referred to as bow shackles, however, a bow shackle typically has a larger, more defined “bow” area than an anchor shackle. This “bow” we’re referring to allows for single or multiple leg slings to be collected in the bow, and for it to be sideloaded. This is an essential process used in a variety of material handling applications, making anchor shackles one of the most widely used of the shackle family.

Wide Body Shackles

You can pick out a wide-body shackle from it’s much larger bow cross-section. This wider shape provides an array of advantages, especially in heavy lifting applications. The significant gain in the sling bearing surface eliminates the need for a thimble and makes for an easier time dealing with synthetic Nylon and Polyester slings. It also increases the useable sling strength, which can greatly improve the overall life of wire rope slings.

Chain Shackles

Chain shackles are often known as D-shackles (or dee shackles) which refers to the “D” shape. This design is narrower than a bow or anchor shackle and generally has a threaded pin or pin close. Their design enables efficient movement of materials, particularly in compact lifting environments. Don’t be fooled by the name “chain shackle”—this type of shackle is used primarily with single-legged wire rope slings and various attachment points. The smaller loop is designed to take high loads primarily in line. Side and racking loads may twist or bend a D or chain shackle.

Theatrical Shackles

Theatrical shackles are specially designed for the entertainment industry. They are designed with all the strength and dependability of a standard shackle but have a black finish that allows it to blend in with the stage surroundings. This allows theatrical riggers (also known as grips) to rig in a safe and dependable way, using industry-standard equipment without distracting from the on-stage action.

Crosby supplies one of the most-used theatrical shackles in the entertainment industry which features a flat black baked-on powder coat finish which gives it the matte black, easy to blend in look you see in the photo.

Remotely Operated Vehicle (ROV) Shackles

ROV shackles are a piece of equipment that is heavily relied on in the subsea industry. In the early days of subsea rigging, standard shackles were being used, but since work with these shackles are done completely by divers or remotely operated vehicles, standard shackle pins and nuts were far too difficult to work with. ROV shackles are specially designed with handles to allow for different robotic grips which make this far easier. They are also made with industry-standard colors to be highly visible which makes them much easier to locate under their conditions.

Shackle Variations

As you saw above, with the anchor shackles and chain shackles, we featured two different variations of that shackle – A screw pin shackle and a round pin shackle or bolt type shackle.

Screw pin shackles

Screw pin shackles feature a threaded pin that is inserted through the ears and tightened. These shackles are often the choice for applications where slings and other hardware are being changed out often, and they are not recommended for permanent or long-term use. Screw pin shackles can be used in multi-leg sling assemblies and where side-loading may occur, but the WLL must be accounted for.

Tip: Be cautious of a live line where the screw pin is being rotated, torqued, or twisted because it can cause the pin to unthread itself. This is also why it’s important to tighten the pin prior to each lift.

Round Pin shackles

Round pin shackles have a round unthreaded pin that is secured in its place by a cotter pin. This variation is the most popular in tie-down, towing, suspension or applications where the load is in a strict line. They are known for performing well under conditions in which they are subject to torque or twisting and are not recommending for overhead lifting. They are also not recommended for use in attaching multiple-leg slings or in any application where load sliding is a possibility.

Bolt Type Shackles

Bolt type shackles can look similar to a round pin shackles at first glance but are a more secure option. It features a combination of a bolt and nut along with the cotter pin. These shackles can be used in any applications appropriate for the round pin shackle or screw pin shackle – With the ability to handle rotation or torque. These are often the most popular choice for permanent or long-term installations because the nut and cotter pin combination eliminate the need to tighten the pin prior to each lift!

How to Choose a Shackle?

  • Refer to the manufacturer’s table for the safe working load limit (WLL) of the shackle. The rated capacity should always be printed on the shackle and be visible.
  • Shackles are sized according to the diameter of the bow section rather than the pin size – So never use a shackle if the distance between the eyes is greater than listed in the manufacturer’s table.
  • Always consult the manufacturer if you are using shackles in extreme conditions such as temperature higher then 204°C or lower than -40°C or exposure to corrosive fumes.

7 Quick Tips For Using Shackles

  1. Inspect shackles regularly and replace any that show any of the following:
    • Stretching and wear
    • Bending
    • Distortion, surface blemishes, wear, and fractures
  2. Never replace the shackle pin with a bolt or unidentified pin – You risk the bolt being bent by the load or possibly completely failing.
  3. Do not allow a shackle to be pulled at an angle, this will cause the legs to open. Avoid this by packing the pin with washers to center the shackle.
  4. Avoid using a screw pin shackle or fit pins in contact with moving parts if the pin can roll and unscrew. If the load shifts, the sling can unscrew the shackle pin.
  5. Do not use round pin shackles restrained by only a cotter pin for overhead lifting.
  6. Never force, hammer or wedge shackles into position.
  7. Never exceed a 120-degree lifting angle when using multiple-leg slings.

Product Spotlight | Lifting Magnets

Product Spotlight: Lifting Magnets

Lifting magnets, also known as magnetic lifters, or magnetic lifting systems, are a versatile piece of rigging equipment that can be used in a variety of applications ranging from lifting small metal pipes or scraps to large heavy metal blocks.

If your business deals with a lot of heavy ferrous metals (generall meaning, containing iron) it may be a good idea to invest in a lifting magnet! Most general permanent lifting magnets have a working load limit (WLL) ranging from 500 to 3,000 pounds, with some electromagnets reaching a WLL of 11,000 pounds – This offers an easy, efficient and cost-effective way to lift an array of metal loads.

Lifting magnets are commonly used in steel mills, scrap yards, loading docks, warehouses, foundries, shipyards, coil and pipe distributors, and other users of applicable steel products.

Types of Lifting Magnets

There are two basic types of lifting magnets – permanent magnets and electromagnets.

Permanent Magnets

Permanent magnets are exactly what you’d think- They’re permanent! What that means is that these magnets use materials that are permanently (or naturally) magnetized to establish the magnetic field. These are called ferromagnetic materials and are usually iron, nickel, or alloys that are made or rare-earth metals.

Fun fact: The main way that permanent magnets are created is by heating a ferromagnetic material to a key high temperature – Specific to each kind of metal. This is similar to the natural process that takes place inside the Earth which is what creates materials that are naturally magnetized.

The majority of permanent lifting magnets can be “turned on” and “turned off” by way of a lever. These magnets generally have two parallel poles which give the magnet a deep penetrating magnetic field for rougher flat surfaces and round pipe or shaft material. When both pole’s fields are lined up, with North to North and South to South, the magnetic field is activated, but when you pull the lever those fields are reversed which will cause the lifting magnet to let go of the load.

Electromagnets

Electromagnets, unlike permanent magnets, rely on electricity to charge the magnet and hold the load to the face of the magnet. This takes place by the use of an energized electrical coil wrapped around a steel core creating a magnetic field. This, of course, means the lifting magnetic depends on a constant power source, which also means a lack of access to power or a power failure can mean the equipment can’t be used.

A safety hazard to keep in mind when using electromagnets in the fact that If the electric current is interrupted, any load being hoisted would be released and dropped. Some electromagnets feature a battery that will protect against accidental loss of power or power outages.

Fully battery-powered magnets are also available which use a self-contained gel cell-type batteries. Battery-powered magnets can be moved from hoist to hoist, offering generous lifting capacity without an external power connection with only a need for periodic recharging.

The Advantages of Lifting Magnets

The three main advantages of lifting magnets are their ability to lift materials without needing to cause surface damage, their cost-saving benefits, and their level of efficiency.

And this is how…

Damage-Free Lifting: Like lifting clamps, lifting magnets provide a way to transport materials without needing to cause surface damage to the load, such as needing to drill a hole to place an eyebolt. They can also minimize the potential of causing scratches, holes, or dents in the material if the magnets are used properly!

Cost-Effective: Since you are able to perform lifts without causing any damage to the load, it results in a more cost-effective lift since there’s no need to then fill and re-finish said damage. It also can be a more costly lift, simply because of the time saved in its efficiency…

Efficiency: Beyond lifting loads with no damage, lifting clamps are also often used to pick materials that may not be accessible enough to properly attach other rigging equipment. For example, if you have a crate of tightly packed materials come in, you may be able to use a lifting magnet to access one part from the top and lift it out quickly and easily! If this crate was say, filled with pipes stacked horizontally, using a strap or chain to lift a single pipe would require one end of the part to be manually lifted in order to pass the strap or chain underneath – Which would at the very least take much more time – If not being totally impossible, impractical or unsafe.

5 Things to Keep in Mind When Using Lifting Magnets

Every type of lifting equipment has downfalls you need to keep in mind to ensure you’re rigging safe – And lifting magnets are no exception to that rule!

Above all, it’s imperative to have proper training on the correct use of ANY rigging equipment you come in contact with on the job. Once you have that base of knowledge, these are a few things you’ll want to be reminding yourself when using a lifting magnet.

1. Air Gaps

An air gap between the magnet and the load’s surface can reduce it’s holding performance. Magnetic lines of force pass easily through ferrous metals, but not air – Therefore anything that creates space or an air gap between the magnet and the lifted object will have a negative impact on the lifting capacity of the magnet. To get the best holding performance, air gaps must be kept to a minimum. You can determine the possibility of air gaps by looking at the profile of the load and its surface. Keep an eye out for things like thick paint, dust, chips, paper or packaging, rust, moisture or textured surface finishing which can all cause air gaps.

2. Magnet Contact to Surface 

Always ensure the entire magnet surface is making contact with the load during the lift. The lifting capacity of the magnet will be reduced in direct proportion to any amount of lack of contact with the material surface.

3. Material Being Lifted

Not all ferrous metals are made alike – Some contain non-magnetic materials that have a negative impact on the magnetic conductance. Heat treatments that affect the structure of the metal can also reduce the lifting capacity.

The lifting force percentage of various materials:

  • St37 (0,1-0,3% C) = 100% lifting force
  • Non-alloy steel (0,4-0,5% C) = 90% lifting force
  • Cast steel = 90% lifting force
  • Alloy steel F-522 = 80% – 90% lifting force
  • AISI430 (magnetic stainless steel) = 50% lifting force
  • Cast iron = 45% – 60% lifting force
  • F-522 tempered (60 HRC) = 40% – 50% lifting force
  • AISI304 (stainless steel/nickel) = 0% – 10% lifting force
  • Brass, aluminium, copper, etc. = 0% lifting force

4. Bending of the Load

If you’re lifting material with a single magnet such as a thin sheet, or something much wider then it is long, be conscious of the load bending and possibly, ‘peeling off’ the magnet. To combat this, thin sheets should be lifted with multiple magnets evenly distributed over the entire surface, and the magnet contact surface should always be in line with the lifted load, not perpendicular to its length.

5. Thickness of the Load

Think of magnetism as lines flowing from one material to the next, sticking them together – like a bunch of invisible nails. Have you ever tried to hang a photo on the wall with a nail and it fell right back out because the drywall wasn’t thick enough for the nail to properly be secured? Magnetism works very similar to that. Only if the load is sufficiently thick is it possible to utilize the magnet’s full capacity. Once this point is reached, a greater material thickness will not result in any additional lifting capacity. If the material you’re trying to lift is too thin, you won’t be able to use your lifting magnets full capacity.


Hercules SLR makes lifting magnets for a wide range of applications using permanent, electro-permanent, battery-powered, and electromagnetic technologies.

Ask The Experts | Sling Identification Tags

One of the first things Inspection Technicians look for when inspecting a rigging and lifting sling is if it has a missing or illegible identification tag. But what do all those markings mean, and why are they important? Hercules SLR rigging experts from Brampton, Ontario are on-hand to explain it all.

Your sling’s identification tag provides you with a wealth of essential information to ensure you are lifting safe including: The manufacture of the sling or where it was most recently repaired, the material of the sling, the working load limit (WLL) of the sling, the serial number, the manufacture’s code or stock number and the type of sling.

This is all information that should be taken into account when creating a lifting plan in order to choose the best type of sling for the job based on the WLL, hitch configuration, and capabilities and different sling angles.

All types of sling will come with an identification tag provided by the manufacturer. Over the lifetime of the sling, it’s important to maintain the tag as best as possible in order to keep it legible. If your tag does become damaged, missing, or illegible the sling should immediately be removed from service.

Keeping up with regular inspections will ensure you are never using a chain sling without a tag in proper condition. If you notice a damaged, missing, or illegible tag before your required inspections -- Simply have the tag replaced. While it is considered a repair, additional proof testing would not be needed at that time (unless otherwise required).

What are the Identification Tag Requirements?

The experts at Hercules SLR in Brampton Ontario are answering some key rigging questions over on the Hercules Group of Company’s social media platforms—And this is one of those questions! In the video below, they (quickly) go over the indication tag requirements for chain slings and show you the difference between a tag in good condition, and one that wouldn’t pass inspection.

Alloy Chain Sling Requirements

Each alloy chain sling must be marked with:
  • The name and trademark of the manufacturer (or name of repair location, if replaced)
  • Number of legs
  • Chain size
  • Grade
  • Length (reach)
  • Rated load for (at least) one hitch type and the angle that it was based upon
  • Individual sling identification (i.e. serial number)
  • Date of Manufacture

To keep up with tips like these, follow The Hercules Group of Companies on Facebook, Twitter, Instagram and LinkedIn!

But what about all of the other types of sling? Keeping in mind what a legible tag vs. an illegible tag looks like, continue on to see what the requirements are for a variety of different types of sling. However -- ALWAYS check in with the regulations in your jurisdiction, as there may be specialized requirements in your location.

Industry Highlight | Film and Television Rigging

film and tv entertainment rigging

Industry Highlight: Film & Television 

Lights, Camera—Rig?!

It’s easy to think of only industrial applications when we talk rigging, but rigging’s found everywhere—Especially behind the TV screen in the entertainment industry.

When making a feature film or TV show, it takes many people behind the scenes running the lights, camera, sets, costumes, makeup…and the rigging! In the film industry, rigging technicians are referred to as grips. Although it’s one of the lesser-known film-industry teams, they are an integral part of many different aspects within film-making.

Next time you’re enjoying a movie full of fun camera angles or high-speed Hollywood chase scenes—Know that a grip made that possible!

What Does the Grip Department Do?

The grip department is in charge of all rigging needs behind the scenes—Lifting, carrying, transporting, rigging, operating, building, and placing production equipment where it needs to be. This means they’re in charge of all equipment that helps to lift or hoist other equipment, often with a main focus on:

  • Camera rigs -- Used to stabilize camera movements or to achieve difficult angles
  • Lighting rigs -- Used to achieve specific lighting techniques or effects.

But it doesn’t stop there. Grips often play more roles then the actors on set, including the role of carpenter, electrician, mechanic, and of course, rigger. They’re the people who make showbiz function.

The grip team is often led by what is referred to as the “Key Grip”, the team lead, and the “Best Boy”, the second-in-command.

Rigging Equipment Used in Film

Grips have to be ready to be thrown into many different types of rigging jobs on set working with equipment like:

  • Tripods
  • Dollies
  • Tracks
  • Jibs
  • Cranes -- Want to see a camera crane in action? Check out this video.
  • Static Rigs
  • Camera Mounts
  • Light Mounts

Rigging Grips often work with specialized companies to tailor-make pieces of equipment to facilitate what’s needed for the specific production. Things like difficult camera maneuvers sometimes require specialized equipment, especially if the filming is taking place in a location with extreme terrain and/or severe weather conditions.

Check out this video by the RocketJump Film School that goes through some of the equipment used by Rigging Grips and how to use it!  Pigeon plate? Gobo head? Quarter apple? Yes, these are real terms and not random gibberish! Of course, it makes sense a fun job like this would mean lots of fun nicknames for the rigging equipment used.

One of the key types of equipment you’ll see featured in this video are different types of lifting clamps. Lifting clamps are used to latch onto plates, sheets, grinders, pipes and other materials for positioning, hoisting and transferring. This eliminates the need for creating a hitch or drilling into the material—A key element when working on sets that can’t be modified for rigging purposes.

Hercules SLR sells Crosby lifting clamps with a variety of working load capacities and jaw opening sizes. Crosby lifting clamps are produced using advanced manufacturing techniques and are able to withstand abusive field conditions. Each clamp is individually proof tested to two times the working load limit and you’ll always find the Crosby logo, working load limit (WLL), jaw opening, unique serial number, and proof load test date permanently stamped on the clamp bodies.

How Grips Facilitate Safety on Set

Like we always say here at Hercules SLR, rigging is all about safety. The end goal of any rigging task should always boil down to getting the job done while keeping the people, product, and environment unharmed. Since Grips are responsible for all of the rigging on set, they also become responsible for some of the most important safety precautions.

As the video above goes through each of the pieces of hardware and how to use them -- They are sure to mention what measures are necessary to keep the equipment safe and secure. Nobody wants expensive lights or other film equipment falling mid-shoot and smashing into a million pieces, and more importantly, nobody wants that to happen over an actor or crew member’s head!

Some of the mentioned safety measures include:

Cotter Pins: Cotter pins act as a locking mechanism and prevents parts from slipping off other parts.

Safety Cables: Safety Chains are an important part of many different applications of rigging and simply stops the fixture from falling if the hardware fails. The safety is attached to the hardware and looped around the beam or bar it is attached to. This way if the clamp fails, the fixture will only drop a short distance and be caught by the chain.

Safety Tip -- Always check the weight rating set on safety chains to ensure it can take the weight of the clamp and anything it’s holding -- Otherwise, it too will break in case of the hardware failing! 

Sandbags: Sandbags are a popular choice for counterweights in the film and theatre industry. In the video, you see them used to weight down a floor plate, but they are also used to secure scenery and props, balance hemp rigging, and a variety of other purposes. They come in a variety of sizes and weights!

Cribbing: Cribbing is used only when clamping on a wooden surface as there is little way to tighten a clamp onto a wooden surface enough for it to be secure, without damaging the wood. Cribbing refers to two pieces of wood that you place on either side of the wooden surface so you may tighten the clamp as much as needed without worrying about damaging the structure itself. This may be seen as more of a cosmetic precaution in other industries, but within the film industry, it’s the only way they can tighten their clamps to a safe point while on the set of a historical home, school or hospital.

Rope Access

As you would imagine, filming doesn’t always take place in locations that are set up for rigging. Often times Grips are faced with figuring out how to rig in tricky locations that may seem impossible to reach. So how do they do it? Rope access!

Rope Access is an innovative access solution that enables a technician to use two ropes and a harness system to position themselves in nearly any work environment. This eliminates the need for scaffolding or other heavy access equipment in locations that simply can’t support it. Using the unique gear system, the grip can maneuver themselves with complete 360-degree mobility in difficult locations while completing the task at hand.

Confined space training may be necessary based on the environment they are working in, and is a great way to ensure the safety of your team while rigging in tight locations. Confined Space Entrant/Attendant
Training (CSEA) is just one of the many courses available at the Hercules Training Academy

Revolutionary Rigging | The Spydercrane

Revolutionary Rigging | The Spydercrane

What’s a spydercrane? Although this spyder is a little bit too big to squish with your shoe… No need to worry arachnophobes, the only thing the Spydercrane and the actual creepy-crawly have in common are it’s 4 long legs which give it a spider-like appearance.

This new crane is much like a boom lift, but its small base and spyder legs or ‘outriggers’ makes it much more versatile than the typical boom lift.

The spydercrane was originally manufactured by Furukawa UNIC Corporation in Japan, and is called the Mini Crawler Crane. Roger Bassetti and Warren Wagoner from Phoenix-based Smiley Lift Solutions saw the crane while on a business trip to Japan and immediately knew that they needed to bring the mini crane technology to the North American Market. So, the Spydercranes we see around the US and Canada come from Smiley Lift Solutions!

What Makes the Sydercrane Special?

Here you see the Sypercrane easily wheeling through a doorway in travel mode

The key feature of the Spydercrane is that they offer a compact design that allows for operation in confined areas. The smaller models are able to travel through a standard width door frame when compact into their ‘travel position’ and the largest of the models are able to travel through a standard double-door.

Travel-mode in the larger Spydercrane models also includes a quick disassemble system that allows the outriggers, boom, and frame to be removed reducing the overall weight of the crane for transporting or hoisting.

You may be starting to get that “it’s too good to be true” ring in the back of your mind thinking it must be an absolute pain to get a crane from all tucked up in travel mode to a useable piece of equipment. However, you can easily set up a typical Spydercrane from travel mode to fully deployed and ready for action in less than 5 minutes! Don’t believe it? Check out this video from GLG Canada showing in real-time just how easy the Sydercrane set-up is!

Many of the models of Sypdercrane come with some other cutting-edge features that make the Sydercrane even more unique. Some of these include:

It’s patented Overturn Protection System: This is comprised of an on-board computer system that continually measures the ground pressure of each of the outriggers through an incorporated “load cell”. During a lift, if the system detects an outrigger is losing ground pressure, an alarm will sound and the crane will start to slow done all functions. If two outriggers start to lose ground pressure, the crane will automatically stop all functions that would put the crane closer to an unsafe position. With the alarm sounding and the crane at a safe stopped position, the operator is able to maneuver the crane back into a safe lifting position.

Variable Geometry Outriggers: The outriggers are designed to allow for lifts in tight spaces. It allows for the outriggers to be locked in numerous positions on the swing, knee, and inner box joints. This means the mini crane can be set up around obstacles, on a catwalk, or in a machinery room with very limited space.

Remote Control and Pressure Sensitive Controls: Unlike most cranes, the Spydercrane offers pressure-sensitive controls that will speed or slow the crane’s functions based on the amount of pressure input by the operator. Most models of the Spydercrane are also equipped with a wireless remote control so the operator themselves can be in the best vantage point for the lift, rather than needing to be on board running controls.

Superior Materials and Construction: The Spydercrane is designed with a hexagonal keeled boom instead of the standard square boom, which adds strength and reduces sway. This is made up of steel that is rated at 140,000 -- 160,000 yield (psi), which is the highest tinsel-yield steel making it thinner and lighter but still stronger than most conventional crane materials.

Spydercrane Models

090 Series

This series is made for job sites requiring a small crane with a boom length of 18 -- 28.4 ft and a maximum lifting capacity of 1,990 lbs. There are three models in this series, the URW094, URW095, and URW095S, which are all generally used in confined spaces where the typical crane would never fit.

090 series cranes can be configured around obstacles, can be set-up on uneven ground, or operated in confined spaces like hallways and up against walls.

200 Series

This series of the Spydercrane is deemed the most versatile and is therefore popular among many industries, On of the most popular uses of this crane is as a glazing tool to set glass and other materials. Three models are available within this series that range in boom length from 24.9 ft -- 28.4 ft and maximum lifting capacity of 5,800 lbs and 6,450 lbs. The geometric footprint of this model of the Spydercrane makes it suitable for use in hallways, balconies, or around obstacles.

All of the models within this series are equipped with the wireless radio remote control mentioned above, which frees the operator from being tethered to the crane.

300 Series

The 300 series Spyderceane is the perfect lifting solution for modern construction sites, as it’s a bit bigger than other models with an increased boom length of 47’10” and a maximum lifting capacity of 5,800 lbs and 6,680 lbs depending on the model.

Though it’s a larger ‘spyder’ when in use, it is only 52 inches wide when in travel mode, which will allow you to move it into any space through a standard double-door -- And it’s zero-emission power options allow for use in indoor construction projects with low ventilation.

500 Series

The 500 series Spydercrane is perfect for steel erection as it offers a lifting capacity of up to 8,920 lbs and a boom length of 8.0 ft. The 500 series Spydercrane is revolutionizing how buildings are built with its heavy-lifting capacity and ability to perform in confined spaces.

This crane is also able to move through a standard double-door when in travel mode and can be used in job sites with low ventilation thanks to its zero-emission power options. And to top it all off, it comes mounted on a dual rubber track with a quick disassemble system that allows the outriggers, boom, and frame to be removed reducing the overall weight of the crane for transporting or hoisting.

700 Series

You may have sensed a theme and can guess that the 700 series Spydercrane is the largest Spydercrane currently available in the North American market. While it is described as a “beast” it still keeps the key feature of the Spydercrane in being compactable down to 5.48′ wide. The 700 Series Spydercrane can really do it all with a lifting capacity of over 6 tons.

Coming jam-packed with all of the features mentioned before throughout smaller series of the crane, the URW706 model has the ability to rotate 360 degrees in places, making it a dream to maneuver through confined spaces. You can find this tarantula level super Spyder crane being used in almost any industrial industry!


No matter how unique and revolutionary your crane is, it’s always important to ensure you’re keeping up with mandatory maintenance and inspections.

Hercules SLR offers crane certifications & LEEA-certified inspections, repairs, predictive & preventive maintenance and crane parts & accessories like wire rope slings, hoists & whatever else you need to lift.

When you spend a long day lifting, hoisting and pulling, your body probably has some aches & pains. Did you know your crane is no different? Just like a weightlifter must take care of their body, watch what they eat and even ensure the palms of their hands are prepared to lift, your crane needs a similar level of care. (And, we know what happens when this level of care is overlooked).

Industry Highlight: A Look into the Quarry Industry

What is Quarrying?

Quarrying is an industry that’s been around for centuries on earth—Essentially since the very beginning. During the Stone Age, one of man’s very first innovations was learning to chip away limestone for making tools like hammers, hand axes, and cutting instruments. Quarrying is essentially the process of extracting natural resources from the earth—Which in modern-day, are used often in the construction industry.

So, what’s a quarry? A quarry, sometimes known as a surface mine, open pit or opencast mine, is the section of earth that the minerals are being extracted from. Quarries produce a range of useful materials like limestone, dimension stone, rock, sand or gravel. These raw materials are used in the foundations of our homes, schools, hospitals, roads and so much more! Nearly two-thirds of all the stone produced in Canadian quarries is crushed and used for concrete and asphalt aggregates.

The image below, created by The Institute of Quarrying, illustrates what a typical quarrying process may look like:

quarrying process

As you can see, quarrying involves many different steps, each involving a different team of professionals and different tools/ machinery. And, of course, this process will look different depending on the material being produced. However, putting the most common practice simply – They begin by digging a pit to access the deposit, and create a vertical face of exposed rock. Then, large chunks are dislodged from the walls, usually through controlled blasting using explosives. This rock is then crushed, impurities are removed and the resulting materials are graded by size before being stockpiled. The materials are then transported by road, rail or sea for use!

What do Quarries Produce?

Like we mentioned, quarries produce a wide variety of natural materials that make up a lot of the build-up world around us. The principal types of stone quarried in Canada are limestone, granite, sandstone, and marble. According to The Canadian Encyclopedia limestone accounts for 79% of the total material quarried in Canada, the largest single material export by far.

Quarries are also known to produce:

  • Gypsum
  • Salt
  • Potash
  • Coal
  • Chemical Grade Limestone
  • Common Clay’s
  • China Clay or Kaolin
  • Ball Cays
  • Silica Sand

These materials then feed into many other industries like ready-mixed-concrete plants, coating plants to produce asphalt and bituminous road-making materials, cement and lime burning kilns, concrete block and pipe works, brick works, pottery works, and plaster/plasterboard factories. Quarrying for many industries is the unspoken first step in their processes, providing them with many vital materials.

Quarrying Safely

Significant safety hazards are present in quarries, as you would imagine when working with heavy pieces of rock, explosives, large machinery and the number of moving parts many quarrying cites have (as you can see in the quarrying process photo above). The Mine Safety and Health Administration reports that incidents involving the handling of materials is the highest cause for injuries in quarries/mines.
