So you want to become a rigger?

A rigger’s main responsibility is to lift, lower, hoist and pull objects using machinery and lifting equipment like synthetic, chain and wire rope slings, hoists and cranes.

They are responsible to make and determine the best configurations and equipment to lift a load, be knowledgeable about safety & operating procedures and know how to fabricate, repair, inspect, install and service rigging and lifting equipment – lifting equipment can range from synthetic slings, wire rope, lifting magnets or cranes and aerial lifting trucks. 

Certain industries, or niche industries (particularly those that require you to use and operate heavy machinery and equipment like cranes and lifting trucks) will require a specific certification to operate them. 

A rigger can provide these services: 

  •  Inspections, on-site or in-shop
  •  Load tests 
  •  Crane repair, sales, inspection and installation
  •  Training
  • Sales and services 

BECOME A RIGGER: TRAINING AND CERTIFICATIONS                                                                

 

 

Many industries that use riggers or rig technician’s don’t require formal training, but do require and/or provide on-the-job learning, training courses and certifications.

However, it may be beneficial to complete a college or technical diploma, which can improve your chances of getting a job or apprenticeship.  

At Hercules SLR, our riggers have a combination of LEEA certifications and on-the-job training from our certified trainers and inspectors.  

Some of these include:

  • Lifting Certifications from LEEA
  • Training Courses 
  • College Diploma 

You also have the option to become a rig technician, which is a Red Seal Trade in Canada. According to the NSAA, a rig technician: 

  • Operates drawworks, rotary equipment and pumps 
  • Inspects rigs 
  • Maintains records of drilling operations
  • Oversees rig mobilization and demobilization 

You don’t need formal education to become a red seal technician, but must complete 9,000 apprentice hours to qualify to complete the rig technician red seal exam. A rig technician is responsible for the above duties, but also operating tools, wearing and ensuring the proper PPE is used and must operate lifting and hoisting equipment.

Welcome to Ontario: Brampton Riggers Talk Chain Hoist Safety

chain hoist,

CHAIN HOISTS

Chain hoists (sometimes referred to as chain falls or their older term, ‘chain blocks’) are popular piece of equipment to lift heavy loads. A chain hoist is durable and allows heavy loads to be lifted with ease since they require much less strength on the part of the rigger. However, this means they’re more likely to be abused since they typically make a lift much easier, but are not suited for every application.

Rigger Colin Grieg of Brampton, Ontario shared what to look for when inspecting your chain hoist and tips for use.

Before you install your chain hoist, check: chain hoist, Welcome to Ontario: brampton riggers talk chain hoist safety, hercules slr

  • Clean the load chain with a solvent, then add slack to the chain and make a link-by-link inspection for nicks, gouges, twisted links and excessive wear or stretch;
  • That the load chain anchor pin is in good condition;
  • That the top and bottom hook safety catches are operating correctly;
  • Check hooks for cracks, damage, distortion and excessive throat opening – a damaged hook often means it was misused and should be removed from service;
  • Hooks swivel freely;
  • Check name plate and see that SWL, ID number and colour code (if used) are clearly visible.

After installation and mounting, check:

  • That load chain sits correctly in the pocket wheel. To do this, run the unloaded hook up and down a reasonable distance – the chain should run free of snags or binds;
  • The hoist is rigged to lift in a straight line from hook to hook;
  • The hoist is free to swivel on the upper hook;
  • For damage on the handwheel and gear covers.

CHAIN HOISTS: hand chain

Although hand chains are not load bearing, make sure:

  • The chain is free of twists and damage to links;
  • The chain is smooth to touch and ‘joint’ links sit firmly in the chain wheel’s pocket;
  • The chain wheel turns freely with no signs of a bent spindle, buckled wheel or damaged ‘chain pockets’;
  • Make sure operation in ‘hoist’ mode produces a ‘hard’ sound – this is the sound of a ratchet running under a spring-loaded pawl.

CHAIN HOISTS: safety first

  • If the chain’s twisted, don’t use the hoist;
  • Don’t use the load chain as part of a sling configuration;
  • Chain hoists can only be used at its maximum capacity to lift a load vertically – if you must lift a load at an angle, the hoist’s capacity is greatly reduced;
  • Don’t operate a chain hoist beyond the capacity specified – you will cause the bottom hook to run beyond it’s range of lift, and possibly add too much weight to the load-chain slack-end anchorage;
  • Don’t lift a load beyond it’s specified SWL (safe-working load);
  • Don’t let dirt, grease or other harmful debris/chemicals to collect in the load’s profile or hand-chain wheels;
  • Don’t use your load chain if it jumps, is not ‘smooth’ or has marks – this means it’s likely ‘out of pitch’ and should be replaced and removed from service;
  • You should not need extra force/strength to operate your chain hoist – if using extra strength, stop the lift immediately and find the cause. (An easy tip? If it takes more than one man – something’s wrong!)

CHAIN HOISTS: post-mount & pre-use 

After you mount your chain hoist but before you actually use it, you should inspect the following:

  • The chain hoist shouldn’t be allowed to lay against a support, since this can cause the hook or frame to bend and damage the unit;
  • Make sure the hoist can swivel through 360° on the top hook;
  • Make sure the ‘member’ the hoist hangs from is sat all the way in the middle of the chain hoist’s saddle.

CHAIN HOIST: crane hooks

When you suspend a chain hoist from a crane hook, stay safe with these tips:

  • The chain hoist’s SWL will be reduced by 15% – this allows dynamic loading;
  • A safety link with a SWL of 5 times the load weight should be fit between the crane hook and load shackle;
  • Before you hoist with a crane, conduct a short lift test with both to make sure the hoist brake is locked.

CHAIN HOIST: storage 

To store your chain hoist:

  1. Raise bottom hook
  2. Wrap load chain
  3. Wrap hand chain
  4. Secure ends

When storing your chain hoist, be sure to: 

  • Lubricate chain hoist with oil or grease – be careful, as misapplied lubricant may enter the brake disc and cause it to fail under the load;
  • Make sure you have a dedicated spot to store your chain hoist – this place should be dry and free from injurious pollution and extremes of temperature;
  • Chain hoists should be suspended by their top hooks, and the hand chain should be clear of the ground – this will prevent damage to the chains;
  • Don’t use strong solvents on your chain hoist – ensure wet or dirty chain hoists are clean before storing.

CHAIN HOIST HOW-TO: light load brake lock-out test

  1. Suspend chain hoist from a suitable lifting point, and apply a load test of 5% chain hoist SWL to the load hook;
  2. Stay clear of the load – raise test load 70 to 100mm from the ground;
  3. Enter restraint pin through lack side of load chain;
  4.  Operate the chain hoist and lower the direction until the restraint pin gives a lock against the heavy pull of the chain hoist;
  5. Remove the restraint pin and make sure the brake engages right away, which will stop the load from dropping;
  6. If the load drops – don’t use the chain hoist. Remove them from service, and have them repaired.

Crane Equipment: cranes, chains & automobiles

crane equipment, hercules slr, rigging services

Cranes have been used since the first century – in that time, they were powered by humans or animals to lift heavy loads. Cranes have adapted and come a long way since – they now use an assortment of crane equipment and hardware to lift, lower and even sometimes move horizontally.

Read on to learn more about the modern variety of crane equipment available and Hercules SLR’s tips for using it.

CRANE EQUIPMENT: an overview

For rigging with cranes, different types of lifting equipment (also known as tackle) are used. These include:

  • Wire Rope Slings
  • Synthetic Slings
  • Shackles
  • Snatch Blocks
  • Hooks
  • Chain Hoists
  • Chain Pullers
  • Eye Bolts
  • Tirfors
  • Jacks
  • Lifting Beam
  • Spreader Beams
  • Beam Clamps
  • Plate Clamps

CRANE EQUIPMENT: wire rope slings

Pay special attention to wire rope slings as they are susceptible to servere wear, abrasion, impact loading, crushing, kinking and overloading – small changes in the slings’ angle affect the safe working load of the sling. Care should be taken around rough edges and wire rope slings – even an edge you might not consider ‘sharp’ can make considerable damage to your wire rope sling, making it unsafe and ineffective. Use sleeves, wear pads or corner protectors to protect your wire rope sling from damage.

Be sure to not drop a load or run a load over the sling – this will crush the sling. Also, don’t stop and start suddenly while you lift and lower with a wire rope sling, as this increases the slings’ stresses and increases possible failures.

WIRE ROPE SLING SPLICES

WIRE ROPE SLING IDENTIFICATION 

There are three ways to identify wire rope slings: the SWL, I.D. number and certificate number.

  1. Hard-stamped on ferrule
  2. A tag which has a wire running through the tag and eye of the sling
  3. Large metal washer where the wire of the sling is passed through when you make the eye of a sling

WIRE ROPE CONFIGURATIONS

There are three main wire rope sling configurations:

  1. Double-Choker Hitch
  2. Pair of Double Wrap Chokers
  3. Single Choker Hitch

Round slings’ are versatile – they’re strong, yet delicate to the load to lift. They’re light, flexible in many directions and malleable which is especially helpful when lifting an awkward or delicate load.

crane-equipment-hercules-slr
Synthetic Round Sling Label

CRANE EQUIPMENT: synthetic round slings 

Round slings’ are not easily damaged by sunlight, humidity, grease, dirt or seawater. Round slings’ are identified by the colour of the label, and also have the SWL on it.

CRANE EQUIPMENT: web slings 

Web slings are suited for particularly those that can be easily damaged. They’re easy to damage if you use them improperly – your web sling shouldn’t touch a sharp edge, heat or chemicals that will cause damage.


CRANE EQUIPMENT: hardware

SHACKLES

For crane lifting, two different shackles are typically used – bow and d-shackles. When using synthetic slings with a crane, two types of shackles are available, wide sling shackle and a round sling shackle. Web sling shackles are wider and bow out in the middle, and round sling shackles are narrow and sometimes have small valleys in the shackle bow, which supports the synthetic strands better.

These prevent the sling from bunching and pinching, which can be an issue with bow or d-shackles – it also reduces the SWL capacity of the sling.

To use shackles for crane lifting safely, follow these tips:

  • Don’t replace the shackle pin with a bolt – only the proper fitted pin should be used. Bolts aren’t meant to take the bend that a pin can handle.
  • Pins must be straight and all-screw pins must be completely seated
  • Cotter pins should be used with all round pin shackles
  • Shackles worn at the crown or pin by over 10% of original diameter should be removed from service and destroyed.
  • Don’t pull your shackle at an angle with a sling or hoist rope – this reduces the shackle’s capacity by 50%. Spacers can be used to centralize the load on the pins with spacers.
  • Don’t use screw pin shackles if the load can roll under load and unscrew

SHEAVE BLOCKS

A sheave block is a single, or multi-sheave block which opens on one side – this opening allows a rope to be pulled over the sheave and eliminates the need to be threaded through the block. When crane lifting with wire rope, sheave blocks can be purchased with configurations for hook, shackle, eye and swivel fittings.

  • Sheave blocks are normally used when it’s necessary to change the direction of pull on the line. When this happens, the stress on the sheave block is significantly greater than the angle between the lead and load lines. 
    crane equipment, rigging services, hercules slr, Crane Equipment: cranes, chains & automobiles
    Pulley with a sheave on a mobile lifting crane, with 25-ton lifting capability
  • When the lines are parallel, 1000lbs on the lead line results in double the weight on the block—2000lbs on block, hook and whatever the connection points are attached to. As the angle between lines increases, the stress on the block and hook is reduced.

HOOKS

Many different hooks are available for lifting and rigging operations – check with manufacturer instructions and warnings before using in a crane application.

When using hooks to lift with a crane, follow these tips:

  • Ensure hoisting hooks are fitted with safety latches (except grab and sorting hooks)
  • Inspect hooks often, looking for wear in the hook’s saddle – check for cracks, corrosion and if the hook’s body is twisted.
  • Inspect the shackle’s throat opening – if the hook’s been overloaded or is weak, the throat will open. If this is the case, remove from service and destroy so no one else attempts to use it.
  • Inspect for cracks in the hook’s saddle and neck
  • Be sure the hook is stamped with its SWL
  • Note that the SWL applies when the load is in the saddle of the hook, as this reduces the SWL.

TURNBUCKLES 

Turnbuckles are sometimes called rigging screws and can be supplied with eye end, jaw end, stub end fittings and/or a combination of these.

  • Use turnbuckles fabricated from alloy steel with weldless construction.
  • If turnbuckles have end fittings, ensure hooks are fit with safety latches.

CHAIN HOISTS / CHAIN BLOCKS 

Chain hoists are often used with cranes to move larger equipment and machinery. Chain hoists vary in size and length, and require little effort to execute a lift.

Chain hoists are durable, but can be damaged easily. To prevent damage, check:

  • The SWL is right for the application/load
  • The chain hoist has been inspected or certified by a third party
  • The hoist’s body is free of cracks or broken castings
  • The hook isn’t deformed and is fit with a safety latch
  • Anchor pins are in place correctly, and are the right type
  • Chain is in good working condition
  • SWL is clearly marked on the chain hoist block

A lever hoist is similar to a chain hoist, but operates slightly different with a lever to lift and lower the load – it can also be used to pull loads.

EYE BOLTS 

When lifting with a crane and eye bolts, ensure eye and ring bolts are made of alloy steel and have shoulders or collars.

Do not load eye bolts at an angle – angular loading reduces the weight of the load they can safely support.

TIRFOR

A tirfor is a mechanical device, equipped with a level handle to operate. They’re used to pull and add tension, and can also be used to lift if they have blocks.

Boris Satiric, is one of our highly experienced Training Specialists. We sat down with him to find out more about him and how he decided to choose training as a career path.

Tell us about your background?

Boris: I spent 12 years of dedicated service in the Royal Highland Regiment of Canada – Black Watch, I trained in, and became qualified in several aspects of leadership, operational skills in different environments, and trained with a wide selection of arms and vehicles.

During my time as a faculty member with the Laval University and Polytechnic school as an Electro Technician LEEA Logofor high tension network I developed my technical knowledge and skill set that helped me manage different technical demands within the industry.

During my 12 years with Hercules, I have obtained many additional skills and qualifications which include being LEEA (Lifting Equipment Engineering Association) certified, with experience with Fall Protection equipment and Tower Cranes etc.

What made you decide to enter this industry?

Boris: My decision was based upon my first impressions and experience that I had when I started working for Hercules.  I knew it was a good fit technically for me, and decided to pursue my career within this field, progressing within the company. I like the challenges the job presents, and every day is different.

What made you want to transition into training?

Boris: With experience in leadership and teaching in Canadian forces I decided to use my teaching and technical knowledge to help other people understand the risks of rigging and lifting, and how to deal with those challenges. During site visits to customers, as an inspector I noticed a lack of understanding dangers and that message MUST be passed on to avoid accidents and uphold workplace safety.

Shackles: A Hercules Hardware How-To

shackles-hercules-rigging

Shackles are typically used as connection points for lifting equipment in many securing and rigging applications.

The type of shackle you use will depend on the lifting operation—Each has a slightly different design to suit them to various functions. There are three main types of shackles typically used for lifting applications:

  1. Dee
  2. Bow (commonly known as an anchor shackle)
  3. Screw Pin (commonly known as a grab)
    shackles-d-shackle-hercules-rigging
    D-Shackle
Dee Shackle
shackles-screw-pin-shackle
Screw pin shackle with cotter/split pin

Dee shackles are mostly used for single-point lifting.

Bow Shackle
shackles-bow-shackle
Bow Shackle

Bow Shackles are designed to be used to carry out multi-point lifts.

Screw Pin/Grab Shackle

Screw Pin or Grab Shackles are used when the shackle is required to pass through an opening, like a pipe or over an object. It is designed with a countersunk pin to facilitate this.

  • Used where a shackle is removed on a regular basis
  • When fitted, the pin must engage with the shackle body and tighten fully
  • Screw pins can be moussed in place for long-term applications, or when there’s a risk of the pin backing out due to vibration, etc. Confirm with your supervisor to make sure this is accepted on your worksite.
Bolt Types: Nut, Bolt and Cotter Pins
  • The bolt type pin (bolt, nut or cotter) is used when a load is permanent or semi-permanent.
  • This requires the rigger to insert a split pin, which captivates the nut on the pin.
  • If fitted correctly, the pin will rotate freely within the shackle body.
Round Pins

The round pin is commonly use for tie-down, suspension, towing and straight line lifting only. Don’t use round pins with multiple slings or where side loading may occur.

Pin Sizing
  • A shackle will be sized from the diameter of the bow, not pin.
  • A pin of a shackle is usually one size larger than the bow to achieve the strength of the bow. Consider this when you order a shackle for specific jobs, like a lifting lug.
Pin Replacement

Never replace a shackle’s pin with:

  • A bolt
  • A differently branded pin
  • An incorrect pin size

Angular Loading

  • Do not exceed included angle of 120° when rigging with shackles and multiple slings.
  • Apply reductions in WLL when you use shackles loaded at angles

Specialty Shackles

Round and web sling shackles that are used with synthetic slings look slightly different.

  • Wide body shackles have a larger D/d ratio for the sling, and improve the life and efficiency of the sling.
  • ROV or remotely operated vehicle shackles are painted bright yellow or white so they are visible in dark waters, the pin is also easier to access with a ROV.
  • Web sling shackles are wider and bow out in the middle
  • Round sling shackles are narrow and sometimes have tiny valleys in the bow of the shackle so the strands are better supported.

How-To: Your Pre-Use Check

Before you use your shackle, you must inspect the following on all shackles:

  • Markings are present, correct and legible including: manufacturer, working load limit (WLL), size, grade/material type
  • The correct pin is fitted
  • No visible signs of damage to the body or pin like nicks, gouges, deformations, stretch, bends, corrosion, etc.
  • No evidence of misuse

In addition to your pre-use check, be sure to avoid swing loading and shock loading, secure sling legs not in use, never leave a load suspended—or walk under it.

How it’s Made

Lifting shackles are manufactured using the drop-forge process.

The drop forge process involves a steel rod hammered with a large ‘drop’ hammer, and a die is fitted to it. This die has the upper impression of a shackle cut into it and this shape imprints on the steel rod. A fixed die has the lower impression of the shackle.

The forged shackle is heated then treated—this ensures a uniform structure and gives the shackle it’s desired uniform thickness.

CM Guest Blog: 3 Safety Tips to Install your CM Trolley

cm-trolley-hercules-slr

Read on to discover tips from rigging and load securing experts at Columbus McKinnon – today, they’re sharing their top three safety tips to remember when you install your CM trolley.

Whether it’s a hoist, trolley or rigging equipment, proper use, inspection and maintenance is important to ensure operator safety at all times. Operators of material handling equipment should adhere to the manufacturer’s installation, inspection and maintenance requirements outlined in the product’s operation and maintenance manual (O&M manual).

Beam clamps and trolleys are critical components of a complete lifting system and demand the same attention to safety as hoists and below-the-hook rigging. The following three safety tips are important to consider when installing and inspecting a CM Series 633 Trolley.

1. CM Trolley Safety Tip: Consider the flange and shape of the I-beam to ensure proper fit and clearance. Measure the I-beam flange and check the distance between track wheel flanges. This distance should be 1/8 to 3/16 inch greater than the beam flange width for a straight runway. Additional clearance may be required for the trolley to negotiate track sections with curves. This clearance should be kept to a minimum to ensure the trolley operates properly on both the straight track sections and the curved track sections. See Figure 1.

cm-trolley-hercules-slr-rigging
Figure 1

2. CM Trolley Safety Tip: Ensure the equalizer pin nuts have been installed properly, in accordance with the O&M manual recommendations. The pins should be tight and locked position. Nuts should be regularly inspected to ensure they’re tight and secure during periodic inspections, which can be monthly or yearly – depending on service. Refer to your O&M manual, and/or ASME Standard B30.17.

3. CM Trolley Safety Tip: It is recommended that the trolley is mounted to the hoist prior to final installation onto the beam. Follow the washer and spacer instructions in your O&M manual to properly set the trolley based on the application’s beam flange width.

Please note: washer and spacer arrangement recommendations shown in the O&M manual are affected by structural variations. The accuracy of the final adjustment should be verified by the installer to ensure proper clearance is achieved between the trolley wheel flanges and the toe of the runway beam. See Figure 2.

cm-trolley-hercules-slr-rigging-services
Figure 2

Remember, any trolley installation should always be done in accordance with the manufacturer’s instructions or the recommendations of a qualified person. Improper installation can cause unequal loading on the trolley and side beam, and as a result can cause the trolley to fall from the beam. It’s also recommended that a load test is performed to 100-125% of the rated capacity of the crane after installation.

Rigging Services

So you’ve got a difficult load to move – whether it’s due to an awkward shape, uneven weight or hard to determine lift points, Hercules SLR rigging services will lift you where you need to be.

We don’t just sell slings at Hercules SLR – we provide inspections, repairs, training and expert advice to keep your projects safe and efficient.

In addition to calculating the load’s weight, there are a few other tips to planning, rigging and executing a successful lift – read on for tips from our expert riggers to secure your hard-to-manage load and accomplish your next lift with ease.

Rigging Services: 3 tips to move an “awkward” load

One

We can’t stress this enough – inspect your equipment! Says rigger Dwayne Fader, Sales Manager at Hercules SLR “Once the equipment is broken, it’s already too late – maintenance and regular inspection is the key to prevention.”

Check the manufacturer instructions or manual for suggested and required inspection times – Unless you want to damage that expensive part, package or material, which costs WAY more over time than simply investing some time and money into inspections.

An informal inspection should be done before each lift, and official inspections should be done according to manufacturer and/or provincial regulations.  

Two

Bigger isn’t always better. Sometimes, you might look at a large object like a vehicle and just think, “well I’ll grab a bigger shackle or sling.” But you’d be surprised at how much support a smaller sling and/or hardware does have.

“Most people are surprised to learn that a small, 2 1/2″ shackle is strong enough to lift a car – bigger shackles are available, but why go bigger when you don’t need to? Often, the smaller piece of equipment will be safer and better suited to the application as it’s meant to support a specific amount of weight.” says Fader.

Using slings which are too big and create bunching are a safety issue, and so is using a shackle which is too big that a sling may slide around in.

Three

Preventative maintenance is a pain, but important. The longer a piece of equipment isn’t inspected or small repairs are ignored, the worse the outcome typically is. A small build-up of issues can eventually lead to large, more expensive repairs. Neglecting preventative maintenance will increase both cost and the risk of injury or death.

Poly-What?! All About Synthetic Slings

what-are-synthetic-slings

Synthetic slings are generally available in two varieties – flat-woven web slings and round slings. Textile slings should perform in accordance with ASME standards B30.9-5.

Synthetic Slings: flat-woven web sling (or webbing sling)

Synthetic flat-woven web slings are usually made with woven polyester, polyamide (which is a fancy word for nylon) or polypropylene, and have an eye (basically, a loop) stitched at each end. They are available in Simplex (one layer) or Duplex (two layers).

Web slings are made with a safety factor of at least 5:1 – although other industries may require a higher safety factor.

Synthetic Slings: round slings

Round slings (also known as ’roundslings’) are made from load-bearing fibres with a protective, abrasion-resistant outer later. Their round form is known as ‘endless construction’, and are available in different lengths and capacities.

Synthetic Slings: beat the heat

Consider the temperature of both your surroundings and the load you will lift – synthetic materials have selective resistance to heat, which will effect which sling you choose.

Synthetic sling heat ranges are:

  • Polyester and polyamide: -40°C to 100°C
  • Polypropylene: -40°C to 80°C

These synthetic materials protect against a variety of chemicals, however – they offer different levels of protection against chemicals like acids. Synthetic sling chemical resistance is:

  • Polyamide (Nylon): Resistant to the effects of alkalis, but is attacked by acids.
  • Polyester: Resistant to acids, but damaged by alkalis.
  • Polypropylene: Shows little affect from acids or alkalis. Sustains damage from solvents and paint.
Synthetic Slings: colour codes

Synthetic material in slings are colour coded, in order to identify them properly. The label will be a specific colour, and may also have the type of material written as an abbreviation.

The colour codes are:

Figure 1: Synthetic Sling Labels

 

Synthetic Slings: eye formations
what-are-synthetic-slings
Figure 2: web sling types

The loop at the end of the web sling is called an eye formation – there are various formations to suit different applications.

There are six different types of web sling types – see figure 2. The six names for these slings are:

  • Type 1—Choker
  • Type 2—Basket
  • Type 3—Eye & Eye
  • Type 4—Twisted Eye
  • Type 5—Endless
  • Type 6—Reversed Eye
Synthetic Sling: round slings

These are made with multiple, high-tenacity yarns, which are covered with a protective sleeve. These are usually made from polyester – but, polyamide (nylon) and polypropylene are available too.

To identify these slings, an identification label is sewn into the cover which details user information and traceability requirements.

They are flexible, light-weight and very flexible.

Synthetic Sling: pre-use inspection

Follow these steps before using your synthetic sling each time – this will ensure you and coworkers will stay safe, and eliminates potential of the sling breaking and damaging the load.

If you find damage on your synthetic sling, it should be removed from service immediately – refer it to a competent person to have it inspected and repaired if necessary.

During your pre-use check, you should:

  • Check the sling label is present and legible and includes manufacturer, rated load for at least one hitch, material type, number of legs (if more than one) and the manufacturers code/stock number.
  • Check that the sling body has no signs of tears, cuts or severe abrasion
  • Check formed eyes for damaged stitching
  • Verify end fittings (where present) function correctly and are undamaged.
  • Check for signs of chemical damage.
  • Check that sling has undergone its periodic thorough inspection.
  • No knots in sling.
Synthetic Slings: shackles, hooks n’ hardware

When you attach a sling to hooks or shackles, take care to ensure the slings don’t bunch around the accessory. Bunching can cause damage since only a portion of the webbing supports the load.

When securing a load with webbing slings, don’t be concerned with the d/d ratio (diameter around the bent sling divided by the body diameter of the sling) – but you must consider the width of the webbing. Follow the manufacturer’s recommendations when you lift with synthetic web slings.

Note: the sling that lies in the shackle fits perfectly – there’s no bunching or a sling that protrudes from the shackle pin.

Chain Sling Wear and Stretch: Are They the Same?

chain-sling-wear-stretch-difference-Chain Sling Wear and Stretch: Are They the Same?-hercules-slr

Read on to learn the difference between chain sling wear and stretch, from our guest bloggers CM.

Chain Sling Wear & Stretch: what’s the difference?

Frédéric, a mechanical engineer who works for a Canadian public utility company, in the auxiliary equipment department asks CM:

“You said a sling should be removed from service if it stretches. But, you also said that 10% of wear is permissible. Does this mean that a stretch of 5 to 10% should be ok, because wear will make the sling stretch (the reach will increase)?”

Henry Brozyna, CMCO trainer & safety webinar presenter answers:

Chain sling wear and stretch are two different things and both will make the sling length increase. So, it is sometimes difficult to differentiate between the two.

Chain Sling Wear and Stretch: Are They the Same?
Unacceptable Chain Wear

Wear will show itself at the bearing points of the links and can exhibit itself in the bearing points of the chain as a groove. A certain amount of wear is permissible and that will happen over time. Check with the manufacturer to see how much wear they allow.

Stretch or elongation are clear signs of overloading. As such, ASME B30.9 Slings lists stretched chain links or components as one of the reasons a chain sling shall be removed from service. The word “shall” in a standard resolves any doubt.  No stretch or elongation is allowable.

Behind-the-Scenes: Life of a Slingmaster Sling

slingmaster-sling-hercules-slr-rigging

slingmaster-slingA SlingMaster sling lives a short,  but full life. We’ve covered the less-talked about non-destructive testing here  and here – but what exactly does destructive testing look like, and why do we use it?

Destructive testing is the process used to test a product and find its ultimate load (the load at which the item being tested fails or no longer supports the load) – in this case, a SlingMaster webbing sling’s breaking or tensile strength. This helps our riggers’ determine how our slings perform under different conditions.

First, one of our industrial seamstresses measures and cuts the length of the sling.

Then, the sling travels to our warehouse for destructive testing. The buttons are pressed, and the stretch begins.

The sling is pulled from each end with increasing force applied in increments – this mimics the sensation of a sling supporting a load.

Watch the video below to see the life-cycle of a SlingMaster sling – from birth, to death-by-destructive testing:
