In-Depth Alloy Chain Sling Inspection | 5 Steps

How should you conduct an in-depth alloy chain sling inspection? Columbus McKinnon is here on the Hercules SLR blog to share what a professional rigger needs to know when they perform an alloy chain sling inspection. 

This blog will cover: 

  • Twists and bends in your chain sling,
  • Nick, cuts & gouges in the chain links 
  • Wear and corrosion 
  • Chain stretch and elongation
  • OSHA guidelines for chain sling inspection 

Read on to become a chain sling inspection pro. 

CHAIN SLING INSPECTION PART 1: TWISTING & BENDING

Consider that chain is evaluated by applying loads in a pure tensile link end-to-link-end fashion and rated accordingly.

Rigging chain around edges or corners alters the normal loading pattern significantly. A lack of proper padding or consideration of the D/d ratio (see above) for chain can result in twisted and bent links. Once a chain is twisted or bent it will alter inner link stresses which can result in failure. For this reason, all chain containing twisted or bent links must be removed from service immediately.

Since 1933, the National Association of Chain Manufacturers represents domestic manufacturers of welded and weldless chain and have conducted D/d testing on alloy chain. 

As a result of this testing, the NACM came out with the chart below which shows reductions in working load limits based on D/d ratio of alloy chain rigged around an edge or a corner. Consult the manufacturer for any D/d below 2.  ASME B30.9 2014 has adopted this chart into the new standard.

CHAIN SLING INSPECTION PART 2: NICKS & GOUGESchain sling link tensile and compression stress pattern

When chain is used to lift, pull or secure materials, the outside surface of the links can come in contact with foreign objects that can cause damage. Nicks and gouges frequently occur on the sides of a chain link, which are under compressive stress, reducing their potentially harmful effects.

The unique geometry of a chain link tends to protect tensile stress areas against damage from external causes. Figure 1 shows that these tensile stress areas are on the outside of the link body at the link ends where they are shielded against most damage by the presence of interconnected links.

Tensile stress areas are also located on the insides of the straight barrels, but these surfaces are similarly sheltered by their location. However, gouges can cause localized increases in the link stress and can be harmful if they are located in areas of tensile stress, especially if they are perpendicular to the direction of stress. Refer to Figure 1.

Figure 2 shows nicks of varying degrees of severity. Reading clockwise, at three o’clock there is a longitudinal mark in a compressive stress area. Since it is longitudinal and located in a compressive stress area, its effect is mitigated, but good workmanship calls for it to be filed out by hand.

At about five o’clock there is a deep transverse nick in an area of high-stress. A similar nick is located at six o’clock in the zone of maximum tensile stress. Both of these nicks can create a potentially dangerous escalation of the local stress and must be filed out with careful attention to not damage other parts of the chain link or chain. A nick that was located at eight o’clock has been filed out properly.

Although the final cross section is smaller, the link is stronger because the stress riser effect of the notch has been removed. The remaining cross section can now be evaluated for acceptability by measuring it and applying the criterion for worn chain. See the “Wear Allowances Table” below.

CHAIN SLING INSPECTION PART 3: WEAR & CORROSION

When used in rigorous material handling applications, chain becomes worn or corroded easily. It is important to inspect chain for defects on a regular basis to avoid an unsafe lifting condition or even operator injury. When corrosion and wear occur, it results in a reduction of link cross-section which can lead to decreased strength of the chain.

Corrosion can occur anywhere chain comes in contact with harsh chemicals, water or when it is used in tough environments.

Wear can occur in any portion of a link that is subject to contact with another surface.

The natural shape of chain confines wear, for the most part, to only two areas. These are, in order of importance, (a) at the bearing points of interlink contact, and (b) on the outsides of the straight side barrels that may be scraped from dragging chains along hard surfaces or out from under loads.

collapsed chain link example
Figure 2: Inspection for interlink wear can easily be detected be collapsing the chain.

Figure 2 illustrates the condition of interlink wear and shows how to inspect for it. Notice how easily such  wear can be detected by collapsing the chain to separate each link from its neighbors. An operator or inspector can also check for corrosion using the same method.

When chain wear or corrosion is observed, the next step is to determine how severe the damage is and if the chain can still be safely used.

General surface corrosion can be removed by cleaning and oiling the chain. If pitting is observed after cleaning and oiling, remove from service. Next, the operator should take a caliper measurement across the worn section of chain and compare it to the minimum allowable dimension for that chain.

See the Wear Allowances chart above for minimum section dimensions or chain wear allowances for Grade 80 and 100 Chain. If the chain does not meet these minimum dimensions, it should be removed from service and replaced.

CHAIN SLING INSPECTION PART 4: STRETCH & CHAIN ELONGATION

A visual link-by-link inspection is the best way to detect dangerously stretched alloy chain links.

Reach should be measured from the upper bearing point on the master link to the bearing point on the lower hook. The smallest sign of binding or loss of clearance at the juncture points of a link indicates a collapse in the links’ sides due to stretch. Any amount of stretch indicates overloading, and the chain should be removed from service.

Note: A significant degree of stretch in a few individual links may be hidden by the apparent acceptable length gauge of the overall chain. This highlights the importance of link-by-link inspection.

Alloy steel sling chain typically exhibits well over 20% elongation before rupture. The combination of elongation and high strength provides energy absorption capacity.

However, high elongation or stretch, by itself, is not an adequate indicator of shock resistance or general chain quality and should not be relied upon by riggers to provide advance warning of serious overloading and impending failure.

Prevent overloading the chain sling by selecting the right type and size of sling. Again, any amount of stretch means the sling’s been overloaded and it should be removed from service.

There is no short-cut method that will disclose all types of chain damage. Safety can only be achieved through proper inspection procedures. There is no adequate substitute for careful link-by-link scrutiny.

CHAIN SLING INSPECTION PART 5: OSHA CHAIN SLING INSPECTION

OSHA Chain Sling Inspection standards have gone through minimal changes since they were published on July 27, 1975. These regulations serve as a guide for rigger’s and other competent personnel that will inspect chain slings. 

Applicable sections of the Code of Federal Regulations (29 CFR 1910.184) include:

CHAIN SLING INSPECTION | 1910.184(d) Inspections

Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a competent person designated by the employer. Additional inspections shall be performed during sling use, where service conditions warrant. Damaged or defective slings shall be immediately removed from service.

CHAIN SLING INSPECTION | 1910.184(e) Alloy Chain Slings

CHAIN SLING INSPECTION: 1910.184(e)(1) Sling Identification

Alloy steel chain slings shall have permanently affixed durable identification stating size, grade, rated capacity and reach.

CHAIN SLING INSPECTION: 1910.184(e)(2) Attachments

  • 1910.184(e)(2)(I)

Hooks, rings, oblong links, pear shaped links, welded or mechanical coupling links or other attachments shall have a rated capacity at least equal to that of the alloy steel chain with which they are used or the sling shall not be used in excess of the rated capacity of the weakest component.

  • 1910.184(e)(2)(ii)

Makeshift links or fasteners formed from bolts or rods, or other such attachments, shall not be used.

CHAIN SLING INSPECTION: 1910.184(e)(3) Inspections

  • 1910.184(3)(I)

In addition to the inspection required by paragraph (d) of this section, a thorough periodic inspection of alloy steel chain slings in use shall be made on a regular basis, to be determined on the basis of (A) frequency of sling use; (B) severity of service conditions; (C) nature of lifts being made; and (D) experience gained on the service life of slings used in similar circumstances. Such inspections shall in no event be at intervals greater than once every 12 months.

  • 1910.184(e)(3)(iii)

The employer shall make and maintain a record of the most recent month in which each alloy steel chain sling was thoroughly inspected, and shall make such record available for examination.

  • 1910.184(e)(3)(iii)

The thorough inspection of alloy steel chain slings shall be performed by a competent person designated by the employer, and shall include a thorough inspection for wear, defective welds, deformation and increase in length. Where such defects or deterioration are present, the sling shall be immediately removed from service.

Please note that while the requirements under (d) for daily inspections are not explicit as to scope or maintenance of records, it is possible that individual OSHA inspectors may have different views on conformity—The minimum 12-month interval inspections required under (e) call for thorough inspection and written records.

To ensure you remain compliant with chain sling inspection in your area, be sure to check both manufacturer and provincial standards.

Rigging and Lifting Slings | All About Synthetics

rigging and lifting slings being sewn at hercules slr

There’s a lot of different terminology and rules to remember about synthetic rigging and lifting slings – but Hercules SLR has you covered. 

When you think of a heavy duty sling, you might wonder why a rigger would choose a synthetic material over something ‘heavy duty’, like chain. They exist for a reason—Some benefits of synthetic rigging and lifting slings include: 

  • Economical
  • Flexible/Easy-to-store
  • Great for applications where steel or wire rope slings could damage a delicate load. 

RIGGING AND LIFTING SLINGS | WHAT THEY’RE MADE OF

Synthetic slings, or textile slings are made out of fabricated materials like nylon or polyester. Colour codes are used to identify the synthetic sling’s material. The colour is identified by a label on rigging and lifting slings – These are: 

  • BLUE: Polyester (ES) 
  • GREEN: Polyamide (PA)
  • BROWN: Polypropylene (PP) 

In terms of their construction, synthetic slings are often known as web slings or round slings. 

RIGGING AND LIFTING SLINGS | SAFETY TIPS

There are many safety tips to keep in mind when lifting with synthetic slings. Here are a few simple safety tips and tricks to keep in mind:

  • Store synthetic slings in a cool, dry place that’s free from exposure to ultra-violet light, like sunlight. 
  • Never pull your sling from under a load 
  • If the tags/labels are unreadable, don’t use the sling 
  • Be careful when using the sling around sharp corners or edges—Sharp corners can tear the synthetic sling 

RIGGING AND LIFTING SLINGS | INSPECTON

Synthetic slings should be inspected on a semi-regular basis. There are three types of inspection you must do with your synthetic sling(s)—These are: 

1) INITIAL INSPECTION

Before using your synthetic sling, a designated person or the user must check the sling to make sure it’s the correct to use for the application, and to ensure the sling meets the manufacturer’s specifications. A designated person is someone who has a recognized degree or certificate in an applicable field (like rigging) or someone who has extensive knowledge, training, experience and has successfully demonstrated the ability to solve or resolve problems that relate to the application.

This inspection should happen whether the sling is new, repaired or altered in any way. 

2) FREQUENT VISUAL INSPECTION 

Whoever is handling the sling, should conduct a visual inspection(s) each time it’s used. Further conditions for frequent visual inspection is:

A) A visual inspection for damage shall be performed by the user or other designated person each date or shift the sling is used. 

B) If the sling has any conditions that could cause hazard, the sling should be removed from service and not returned until it’s been approved by a designated person. 

3) PERIODOC INSPECTION 

Each part of the sling must be inspected individually—Take care to expose and examine all surfaces and individual component. 

Periodic inspections should not exceed one year—Inspect your synthetic sling at least once annually. Inspection frequency is based on how often slings are used, the kind of lifts being made, experience gained on service life of slings and how severe service conditions are.

Severe service conditions are defined as: 

  • Normal service—Yearly
  • Severe service—Monthly to quarterly
  • Special service—This is recommended by a qualified person 

When you inspect your sling, look for these conditions: 

  • Bent or twisted fittings 
  • Chemical damage
  • Crushing or knots 
  • Cuts and broken stitching 
  • Exposed internal cover due to cut or abrasion 
  • Heat damage 
  • Holes, cuts, tears or snags 
  • Missing or illegible sling identification
  • Severe abrasion
  • Twin path tell-tails not extending 1/2″ past the tag area 
  • Ultra-violet ray damage
  • Worn or broken stitching

RIGGING AND LIFTING SLINGS | KNOW YOUR ANGLES 

What do we mean when we discuss sling angles? Sling angle is the space where the sling and the horizontal part of the load meet. 

Rated capacity, rated load or working load limit refers to the maximum working load that the sling manufacturer says the sling can hold. The terms ‘rated capacity’ and ‘working load limit’ are commonly used to describe rated load. The angle is important as the sling angle creates tension, which can impact the rated capacity of the sling.

Safe sling angles are typically 45­° greater from the horizontal point of the load. 

When we talk about sling angles, it’s important to talk about sling hitches. Hitches refer to the different way a sling can be applied to a load. The angle of multi-leg slings will effect the rated capacity of the bridle or multi-leg sling.

The most common types of hitches found in rigging are: 

  • VERTICAL: Method of rigging a web sling where the load’s attached to one end of the web sling, and the other end of the web sling is attached to the lifting device. 
  • CHOKER: Method of rigging a web sling in which the web sling is passed around the load, then through itself, then attached to the lifting device. 
  • BASKET HITCH (90°): Method of rigging a web sling where the web sling is passed around the load, and both ends are attached to the lifting device. A method of rigging a sling where it’s passed around the load, then through one loop eye, end fitting, or other device, while the other loop eye or end fitting at the other end is attached to the lifting device. Any hitch less than 5 degrees from the vertical may be considered a vertical hitch. 
3 most common rigging hitches
3 Common Rigging Hitches with Synthetic Slings

The degree of the angle determines the rated capacity of the sling—To find out if a sling has the rated capacity you need for a lift, take the angle between the sling leg and the horizontal, then multiply the sling’s factor. 

As the sling angle decreases, so does the rated capacity. Here’s a chart for example:

SLING ANGLE DEGREES LOSS FACTOR
901
850.996
800.985
750.966
700.94
650.906
600.866
550.819
500.766
450.707
400.643
350.574
300.5

 

RIGGING AND LIFTING SLINGS: OTHER FACTORS THAT REDUCE CAPACITY

It’s important to remember that rated capacities are based on perfect conditions. There are many other factors that reduce capacity. These include:

  • Swing: Suspended loads can swing, which place more dynamic forces on the hoist in addition to the weight of the load. These additional forces (see point below) are difficult to quantify and account for, and could cause tip-over of the crane or failure of hoisting hardware. The force of the swinging causes the load to drift away from the machine, which increases the radius and side-loading on equipment. Keep the load directly below the boom point or upper load block. This is best accomplished by controlling the load’s movement with slow motions. 
  • Condition of equipment: Again, WLL and rated capacities are based on perfect conditions – this includes equipment and hardware. Damaged equipment should be taken out of service immediately. 
  • Dynamic forces: WLL and rated capacities are meant for static loads. Safety factor accounts for the dynamic motions of the load & equipment. 
  • Weight of tackle: Hoisting equipment’s rated capacity doesn’t account for the additional weight of blocks, hooks, slings, equalizer beams and other parts of the lifting tackle. The weight of these accessories combined must be added to the load’s total weight, the capacity of the lifting equipment including design safety factors and should be large enough to account for the extra load to lift.

Tips for Taglines | Training Tuesday

riggers using taglines to control and secure a load

TRAINING TUESDAY | TAGLINES

Taglines — What are they, what are they used for and why do we rig with them? We’ll tell you — Welcome to the new series from Hercules SLR, called Training Tuesday. 

In this series, every Tuesday, we’ll bring you a new topic about rigging, hoisting, fall protection, heavy machinery, workplace safety and more.

We’ll cover why the issue is important, advice for safe-use, application pointers so you get the most from your gear and training tips for employers and employees. 

This week, our Training Tuesday topic will be Taglines—In this blog, we’ll cover:

  • What’s a tagline?
  • When to use a tagline? And how to do it safely 
  • What not to do when using a tagline to lift 
  • Tagline standards, rules and regulations 

TRAINING TUESDAY | WHAT ARE TAGLINES? 

So, what’s a tagline? A tagline is a line (often constructed of synthetic materials, otherwise known as a ‘soft line’) that attaches to a load and provides control while minimizing movement of the object during lifting operations. Simply put, taglines are used to prevent line rotation when lifting with cranes. 

Using taglines may add potential hazards to personnel involved in the lifting operation. These hazards should be assessed before the lifting operation begins. So, when is it appropriate to use a tagline to help secure a load? There are a couple of conditions: 

  • The crane’s load will swing back and forth (etc. a load on an especially windy day) 
  • The load’s rotation will create hazards 
  • A load needs to be positioned or connected in a particular way when it lands 

Read on for more tips to use taglines safely, what you should never do when securing a load with taglines and more tips for best-use. 

TRAINING TUESDAY | SAFETY TIPS FOR TAGLINES

When rigging with taglines, make sure:
  • Tagline is free of knots 
  • Taglines should have sealed ends so they don’t fray
  • One rigger should be assigned to each tagline and be able to safely position themselves away from the load 
  • To secure long loads with taglines, attach them to the very ends 
  • Taglines should be long enough that the assigned rigger can be in a safe location for the duration of the lift
  • Taglines must be held so the rigger can easily release the line if the load swings—This is important since it prevents the rigger from being thrown off-balance and into a more dangerous position
  • Wear the proper protective gloves when you handle taglines 
  • You know the working-load limit of the tagline 
  • Taglines are fit according to your company’s procedures/regulations 
  • Taglines are attached at a spot where they can be easily removed 
  • The load rotation can be controlled with taglines (if it’s rotating/swiveling uncontrollably).
When rigging with a tagline, do not: 
  • Use taglines if they’ll create any sort of safety hazard
  • Use taglines to control a lift during inclement/adverse weather conditions 
  • Go near or beneath, or let another rigger go beneath a load to retrieve a tagline 
  • Detach the tagline from the load until the crane operator and banksman position the load in its final location, with no load on the lifting gear  
  • Loop the tagline around your wrist, or any other part of the body
  • Use taglines for routine back-loading of supply vessels
  • Temporarily or permanently attach, loop, twist or tie a tagline to adjacent structures or equipment in an attempt to control the load
  • Use a tagline if there’s not enough clearance-room for the rigger to move from any spots where the load could fall 
  • Operating the tagline will cause a handler to be near a pinch point (A pinch point is any area where personnel risks having their extremities caught by a machine or equipment)
  • Allow taglines to fall into rotors 
  • When ever possible, attach your hook to a load block to prevent twisting of the hoist line. 

« More employees are injured in industry moving materials than while performing any other single function. »

« More employees are injured in industry moving materials than while performing any other single function. In everyday operations, workers handle, transport and store materials. They may do so by hand, manually-operated materials handling equipment, or by power-operated equipment, » says the U.S. Department of Labour/OSHA Training Institute. 

This is why it’s important to eliminate risk whenever possible and ensure taglines provide more help than hazard to a lift—Remember when not to rig with taglines.

TRAINING TUESDAY | TAGLINES & OSHA STANDARDS 

In Canada, each province has their own specific Occupational Health & Safety Laws, which are usually broken down into:

  • Occupational Health & Safety Acts 
  • Occupational Health & Safety Regulations/Codes 
  • Standards 
  • Industry Association Code of Practice 

Be sure to check with regulations and standards in your province for further details on how to use taglines. 

TRAINING TUESDAY | WHEN TO USE TAGLINES

It’s important to note that taglines only work in tension. The handler should be able to hold the tagline at waist or shoulder-level—When the tagline must be held higher than this, it’s less effective it is at controlling the load. 

Sometimes, if the rope’s not long-enough, the handler’s instinct will be to pull the rope down, and end up pulling down on the load. This makes the tagline non-effective, and creates a more likely scenario that the load will fall on the handler. 

Yes, we discuss how taglines can create pinch points, however they can also help prevent them in some cases. Sometimes a load can twist around the crane that’s lifting it, and cause the load to bounce off nearby equipment or other parts of the crane—this can create pinch points, so taglines can be an effective way to control this.

TRAINING TUESDAY | CONCLUSION 

Taglines provide extra security for positioning and landing difficult loads, particular in inclement weather—However, rigger’s should exercise caution before using taglines extraneously.

Using taglines when unnecessary can sometimes create more hazards on-site, like producing pinch points or obstacles that could injure workers—This is why a rigging plan is especially important before conducting any lift , to ensure taglines are the right securing equipment for the application at-hand.

Taglines should be used to control block rotation, secure the load’s landing or when inclement weather will cause the load to swing uncontrollably—But don’t use them if they create more hazardous conditions for the handlers, rigger’s and any other personnel on-site. Remember, preventing injury is the priority of any lift—Safety should always be #1.

CM GUEST BLOG | SAFE ENTERTAINMENT INDUSTRY RIGGING 

Columbus McKinnon joins us on the Hercules SLR blog to share their best tips for safe entertainment industry rigging.

Read on & learn how to set-up and stay safe in the theatre, arena or wherever the lights, camera & action take you—What are you waiting for, check out CM’s entertainment industry rigging tips.

ENTERTAINMENT INDUSTRY RIGGING TIP #1 | always check for damaged cablesentertainment industry rigging, check cables, hercules securing, lifting & rigging

Before you plug it in or switch it on, always check for damaged cables. It only takes a few seconds to make sure things are safe, but it takes a lot longer to heal from electrical burns. Always assume there could be a hazard. 

 

ENTERTAINMENT INDUSTRY RIGGING TIP #2 | help fight the good entertainment industry rigging safety, check cables, hercules securing, lifting & riggingfight against rust & corrosion 

Keep up with frequent and periodic inspections of your rigging and hoists. You can find details on what is required for frequent and periodic inspections in your Lodestar Manual, as well as in the ANSI E1.6-2-2013 standard.

 

ENTERTAINMENT INDUSTRY RIGGING TIP #3 | inspect your rigging before and after every useentertainment industry rigging safety, check cables, hercules securing, lifting & rigging

Like many riggers, synthetic slings are super strong, but also very sensitive to being rubbed the wrong way. Always take a moment to inspect your rigging before and after use. The scuff mark on this sling was an indication to examine for other damage.

If you can see the core material, then it is time to retire the sling. Sling inspections are 50% visual and 50% tactile.

ENTERTAINMENT INDUSTRY RIGGING TIP #4 | before getting into entertainment industry rigging safety, check cables, hercules securing, lifting & rigginga high-reach, or any other aerial work platform, take a few minutes to do a pre-operational inspection of equipment

Working safely at height requires constant attention to detail.

Before getting into a high reach, or any type of aerial work platform, take a few minutes to do a pre-operational inspection of the equipment. Whether the damage in these pictures occurred from corrosion or a single incident, it is an indicator that there may be other unseen problems with this machine. 

ENTERTAINMENT INDUSTRY RIGGING TIP #5 | look out for those who can’t do so for themselves entertainment industry rigging safety, check cables, hercules securing, lifting & rigging

Some days you never know what nature is going to put in your path. While our own safety is paramount, it is also important to look out for those who cannot do so for themselves. Be nice to our little furry and feathered friends. Find a gentle way to help these birds relocate to a more suitable home.

ENTERTAINMENT INDUSTRY RIGGING TIP #6 | check compatibility between rigging attachments and their respective capacities  

Rigging to the low steel and need maximum trim height? Using a beam clamp is a more practical alternative than rigging with wire rope slings when you have to get tight up to that beam. Remember to check for compatibility between rigging attachments and their respective capacities.

ENTERTAINMENT INDUSTRY RIGGING TIP #7 | hardware compatibility is critical to safe rigging applications entertainment industry rigging safety, check cables, hercules securing, lifting & rigging

Hooks are designed to take load in the “saddle” or “bowl”. The safe working load of a hook can be severely reduced when loads are applied to the tip. While this example may or may not lead to a failure, it still begs the question of what other shortcuts or missteps may have been taken during this installation? Will that loose piece of sash cord get sucked into the hoist? Safe rigging is all about attention to detail.

ENTERTAINMENT INDUSTRY RIGGING TIP #8 | know your voltage setting 

Do you know which voltage setting your CM Lodestar is set for? It only takes a minute to pull the cap off and check. Most entertainment applications will use the low voltage option. Luckily, Lodestars are equipped for dual voltage options. 

ENTERTAINMENT INDUSTRY RIGGING TIP #9 | consider using clove hitches  entertainment industry rigging safety, check cables, hercules securing, lifting & rigging

Using a clove hitch on the chain, 6-12 inches below the hook, can make it much easier to clip into your rigging point. With one hand (or foot) on the rope, the other is free to complete the attachment. Also, there is no chance for the rope to get pinched between the hook and shackle. Always remember to back up that clove hitch with a half hitch on top to prevent roll-out.

 

 

 

 

 

ENTERTAINMENT INDUSTRY RIGGING TIP #10 | important truss tower safety considerationsentertainment industry rigging safety, check cables, hercules securing, lifting & rigging

Portable truss towers have become very popular in recent years. They are easy to erect and can be installed quickly with a small crew. Three important safety considerations for these systems are:

  1. Evaluation by an engineer for site-specific considerations and high wind action plans.
  2. Maintaining weather monitoring systems, so prompt action can be taken should inclement weather occur.
  3. Securing the load from swinging with proper rigging hardware. The lever hoists, in this example, are also being used to focus the speakers. 

ENTERTAINMENT INDUSTRY RIGGING TIP #11 | inspect your PPE before each use

The personal protective equipment we use is only effective if we inspect and care for it properly. Before putting on that harness or lanyard, take a moment to inspect all of the stitching, buckles, and attachments.

Make it a habit to do “buddy checks” with your co-workers too. A second set of eyes may see something yours did not. If it doesn’t look right, don’t use it.

ENTERTAINMENT INDUSTRY RIGGING TIP #12 | make an effort to seek knowledge and personal growth

No matter how much you already know, there is always room for more training. The culture of our industry is more focused on training than ever these days. Whether you find that training online, on the job, or in a classroom, never be afraid to ask questions. The more knowledge we have, the safer we, and those around us, will be. entertainment industry rigging safety, check cables, hercules securing, lifting & rigging

Jenn Connolly, Sarnia Ontario Branch Manager: Leading with Service

sarnia hercules slr, hoisting equipment

Jenn Connolly is our talented, energetic branch manager at our Sarnia, Ontario branch—She’s worked with people her entire career and knows how to keep her customers and team happy.

Read on to learn more about how Jenn honed her service skills, her tips for working with people and how she’s grown the Sarnia branch. 

Tell us about your educational/professional background:

I’ve been in customer service since I was twelve! MY grandparents owned a small business, so during school holidays I would work there and help with sales. I’ve worked in a variety of roles, whether at a bar, gas station, a McDonalds, or all three at once—Which I have done before.

I worked in call centres for about 6 years before I joined Hercules SLR, and was excited to make a switch.

Wow! That’s a lot to juggle—How did you do it? 

I was juggling a lot more than jobs, too! I lived in Hope, B.C. at the time. Throughout the week and my days would start at 5am where I’d head to a shift at McDonalds, then I’d head to an evening shift at a gas station and my days would end at 10pm. Oh, and Thursdays, Fridays and Saturdays I would also work as a bar waitress—Three shifts in total!

Customer service is one of your strengths—How do you lead with service?

A huge portion of it is to know the product. Customer service means being positive, outgoing and working with everybody—Customers and coworkers. It’s important to meet their needs and know what they’re talking about so you can truly provide them with the best service or product for their issue. I work hard everyday to ensure everyone is happy. 

Why did you decide to work for Hercules SLR?

Call centres in Sarnia, Ontario were always closing! (laughs) After they closed, I worked at the Waterville car plant, realized during my first few days that it wasn’t for me.

I had interviewed with Jason McNutt, and basically hounded him for days! When he told me I had the job, I quit the plant and started a week later—It had a come-home feel for me. 

The branch opened in January, 2013 and I’ve been here since. When I started, I trained in Brampton for 3 days—The last time I got that dirty was when I had a job pulling apart lawnmowers at 14! I was the sole employee here for awhile, which was hard to get used to—But it’s been so gratifying to watch our growth. 

Where have you traveled during your time at Hercules SLR? 

Jenn Connolly, Branch Manager

For work, I’ve travelled to Hamilton, Brampton and finally, finally made it to Nova Scotia to visit the Dartmouth branch and head office!

For pleasure? I go to Cuba twice a year. I actually met a Cuban family through a friend, and went straight from the airport to their house! I stay with them while I’m there, and it’s so nice—They actually have a small place near the back of their property, so my friend and I even have our own place there! They’re super nice to us, and we always bring some Canadian treats for them, too.  

Where have you enjoyed traveling to most for training with Hercules?

I’ve enjoyed travelling to our Brampton branch (which was actually in Mississauga at the time!) I’ve also done a lot of training at the Hamilton branch—Going there is always such a pleasure since I communicate with them everyday. It’s nice, and I think important to reconnect with them and remember they’re not just emails and phone calls. 

Is there anywhere that you would like to travel to in the future with Hercules SLR?

Ideally, I’d like to visit all of them! I’ve never been to Newfoundland, and would love to see the branches there.

What’s something you’re most proud to have accomplished in your career at Hercules SLR?

I’m just proud of it in general—I love seeing our branch and company succeed in general. I’ve been at the Sarnia branch from the beginning, and I’ve been so proud of its growth. I’m excited for new employees that have recently joined our team, new clients and inspection opportunities. 

In terms of being proud? I’m proud of my customer service skills! Not everyone can work with the public, and do it well and enjoy it—I’ve really found my niche. 

What’s something you love about the securing, lifting and rigging industry?

It’s always changing! No two days look alike. There can be one question with ten answers, and our goals transform constantly—No two lifts are the same, and each client’s needs are specific to the job, job site & conditions and worker’s themselves. 

There are legislations and regulations that change constantly, too, so you have to be on top of your game.

What sort of challenges do you face as a woman in this industry, and how do you overcome/face them?

I think it’s important to know that rigging isn’t about gender, it’s about safety, no matter who you are. We have to work as a whole so we can do the best we can for our coworkers and customers—This is how I see it. I love that my customers just ask for Jenn, because I know my stuff.

Give us some advice for young women who work, or want to work in an industrial environment:

Some of the best advice I can give is to be willing to change. Everyday won’t be the same, and it’s important to work with it, not against it. Dealing with growth and change can definitely be a struggle for me, but Rose (Hercules SLR’s Vice-President of Operations) has taught me (and still reminds me!) that it’s normal to feel uncomfortable, but still important to learn to work with changes.

Don’t make the sandpaper so smooth you can’t work with it—Grit can be a good thing!

What should you do before you use a hoist?—Hercules How-To

what should you do before you use a hoist

HERCULES HOW-TO: WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? 

What should you do before you use a hoist? If you’re a rigger, or have worked in construction, you’ve likely used some sort of hoist before. Hoists are mechanical devices use to lift, pull and hoist, and are equipped with a pulley. They’ve also been around for awhile—historians haven’t been able to pinpoint exactly when the first hoist was used, but even Leonardo da Vinci had a hoist design.

Since then, hoist technology has come a long way – hoists are available in manual, electric, hydraulic and even universal styles. They’re used in a number of different industries. Today, we cover more about hoists used for securing, lifting and rigging applications and what exactly you should do before you use one. 

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? HAZARDS 

We talk a lot about hazards, how to avoid them and prevent them on a job site. There are a number of hazards that present themselves at work – both chemical and physical. When rigging with hoists, there are a number of hazards there.

Some of the most common hazards are: 

  • Falling equipment, materials, etc. 
  • Electrical issues 
  • Loading hoist beyond it’s WLL or SLL, known as overloading 

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? TRAINING

It’s important that anyone using the hoist, or operating rigging equipment in general, has proper training in hoist safety and operating procedures. Hoists are often used in rigging, and are commonly-known as a component for cranes. Hercules’ highly-skilled trainers teach a variety of courses that will prepare you to rig with hoists.

The Hercules Training Academy courses include: 

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? TYPES OF INSPECTION

According to the ASME (American Society of Mechanical Engineers), there are thee main types of inspection that rigger’s (or any end-user of hoisting equipment) have to do. 

PREOPERATION INSPECTION

Before each shift, have a qualified person inspect hoisting equipment for:

  • Ensure mechanisms operate properly – check for unusual sounds, and make adjustments as needed 
  • Hoist limit device, for electric or air-powered hoists without a load on its hook: The load block should inch on limit device, or run at a slow speed when on multi-speed or variable-speed hoists. Using travel-limiting clutches as a limit device? Follow inspection methods detailed in the travel-limiting clutch’s manual. 
  • Hoist’s braking system
  • Check lines, valves and other parts of air system for leakage
  • Check hooks & latches; ensure hooks are in accordance with ASME B30.10
  • Check hoist rope for gross damage, and these features that could cause immediate hazards, including:
    • Rope distortion: kinking, crushing, unstranding, bird-caging, main strand displacement and/or core protrusion
    • General corrosion
    • Broken or cut strands 
    • Number, distribution and type of broken wires (if visible)
  • Check load chain for gross damage, and any of these conditions which can be hazardous for work. These are: 
    • Gouges, nicks, weld splatter, corrosion and/or distorted links. 
    • Test the hoist with the load in lifting and lowering directions, and watch the operation of the chain and sprockets. The chain should feed smoothly with the sprockets. 

FREQUENT INSPECTION

Frequent inspections should happen continually, during use and rest periods. During frequent inspections, a qualified person will determine if issues found are hazards and whether the hoist should be removed from service temporarily, inspected further and repaired, or removed from service permanently and replaced. 

During frequent inspections, inspect:

  • Operating mechanisms for proper orientation, adjustment and unusual sounds
  • Braking system
  • Lines, valve and other parts of air systems for leakage
  • Check hooks & latches; ensure hooks are in accordance with ASME B30.10
  • Hoist limit device, for electric or air-powered hoists without a load on its hook: The load block should inch on limit device, or run at a slow speed when on multi-speed or variable-speed hoists. Using travel-limiting clutches as a limit device? Follow inspection methods detailed in the travel-limiting clutch’s manual. 
  • Check hoist rope for gross damage, and these features that could cause immediate hazards, including:
    • Rope distortion: kinking, crushing, unstranding, bird-caging, main strand displacement and/or core protrusion
    • General corrosion
    • Broken/cut strands 
    • Number, distribution and the kind of visible broken wires 
  • Check load chain for gross damage, and any of these conditions which can be hazardous for work. These are:
    • Gouges, nicks, weld splatter, corrosion and distorted links 
    • Test the hoist with the load in lifting and lowering directions, and watch the operation of the chain and sprockets. The chain should feed smoothly with the sprockets. 
    • Check rope/load chain reeving and make sure it complies with the manufacturer recommendation. 

PERIOD INSPECTION 

Periodic inspections can be conducted wherever your hoist is set up, as they don’t require the rigger to disassemble the hoist. 

  • Open or remove covers and other items to inspect components. 
  • A qualified, competent person will determine if conditions found during inspection make a hazard, or whether disassembly is required.
  • Inspect the following for wear, corrosion, cracks and distortion:
    • Ensure fasteners aren’t loose, or on the verge of coming loose 
    • Load blocks
    • Suspension housings 
    • Hand chain wheels 
    • Chain attachments 
    • Clevises
    • Yokes 
    • Suspension bolts
    • Shafts
    • Gears
    • Bearings 
    • Pins
    • Rollers
    • Locking and clamping devices 

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? WHEN DO I INSPECT?

We’ve covered the three types of hoist inspection required in Canada, according to the American Society of Mechanical Engineering (ASME). This is when you should conduct each type of inspection.

1. PREOPERATION INSPECTION

A visual inspection should be conducted before each shift. This inspection does not have to be recorded, but a designated, competent person should inspect the hoisting equipment.

2. FREQUENT INSPECTION

Frequent inspections, like pre-operatation inspection, are visual and don’t need to be recorded but should be done by a designated, competent person. Just how often are ‘frequent’ inspections, you ask? 

A) Normal Service—Yearly

B) Heavy Service—Semiannually

C) Severe Service—Quarterly 

3. PERIOD INSPECTION

Visual, period inspections should be conducted by a competent person who makes records of external coded marks on the hoist. This is acceptable identification in lieu of records. Periodic inspections should be done: 

A) Normal Service—Yearly

B) Heavy Service—Semiannually

C) Severe Service—Quarterly 

Since this article is about what to do before using a hoist, we’re going to focus on what your preoperation – or, preuse inspection should include. 

  • The pre-use inspection should be performed during each shift before the hoist is used. 
  • A competent, qualified person will determine whether conditions found during inspection could create a hazard and, if a more detailed inspection is required. 
  • Inspect the following:
    • Operating mechanisms for proper operation, proper adjustment and unusual sounds.

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? HAND SIGNALS

Hoisting hand signals.

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? KNOW THE ROPES  

Before operating a hoist, it’s important to conduct an inspection before-hand. The inspection should consist of: 

Rope Type: Ensure you select the proper type of wire rope. The wire rope you select will depend on the hoist type and the features of the load you will lift. 

Are you familiar with the concept of rope stability before using that hoist? Hoists often use wire rope, which can kink, twist or become crushed if the wrong type or the wrong application is used. 

Drum crushing is a type of rope deterioration that can happen with multiple layers of wire rope on a drum. Whoever inspects the wire rope must evaluate the potential for wire rope crushing. Inspections should detect points where crushing is more likely to happen, and the level of deterioration and appropriate course of action (ex. repair or replacement) can be made. 

WHAT SHOULD YOU DO BEFORE YOU USE A HOIST? YOUR CHECKLIST

Before rigging or lifting with a hoist, know: 

 

  • The hoisting devices capacity
  • The WLL of: the rope, slings and hardware, and the rigging hardware’s weight

Here are some basic tips from CCOHS for inspecting your hoist: 

  • Pre-Lift: Make sure both hooks (upper and lower) swivel, replace worn chain or wire rope and tag it so it can be removed from service.
  • Post the SLL (safe load limit) in the hoist. 
  • Daily: Inspect hooks, rope, brakes and limit switches for wear and damage.
  • Ensure swivels move freely and there are no cracks or breaks in the hook. 
  • Conduct periodic inspections according to manufacturer rules or legislation.

CROSBY HOOK HOIST INSPECTION

TAKE THE CROSBY QUIZ

So you think you know how to inspect a hoist hook? Prove it. Danny Bishop, Director of Training at The Crosby Group has put together this quiz to test your hoisting hook inspection know-how. 

It’s important to know what makes a hook no longer safe to use – there are a number of factors that contribute to this, and they aren’t always glaringly obvious like being broken or crooked.

Hooks that don’t pass inspection can cause the load to release, and this can result in damaged materials, injured workers or legal consequences. It’s important to conduct inspections before you use the sling – each time

Take the Crosby Group Quiz and find out if you’re a hook inspection pro – or if you have a bit more to learn.

ASME STANDARDS

There are ASME Standards that apply to rigging, and more specifically, hooks for lifting. Although they’re not law themselves, these standards are important to know as they’re directly quoted in Canadian legislation. Be sure to check the manufacturer warnings, usage instructions and other recommendations that may apply to the equipment you’re using.
