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.   

Wire Rope Sling Requirments

Each wire rope sling must be marked with:
  • The name and trademark of the manufacturer (or name of repair location, if replaced)
  • Rated load for (at least) one hitch type and the angle that it was based upon
  • Diameter or size
  • Number if legs (if more then one)

Metal Mesh Sling Requirements

Each metal mesh sling must be marked with:
  • The name and trademark of the manufacturer (or name of repair location, if replaced)
  • Rated load for (at least) one hitch type and the angle that it was based upon
  • Individual sling identification (ex: serial number)

Synthetic Rope Sling Requirements

Each synthetic rope sling must be marked with:
  • The name and trademark of the manufacturer (or name of repair location, if replaced)
  • Manufacturer’s code or stock number
  • Rated load for (at least) one hitch type and the angle that it was based upon
  • Type of fiber material
  • Number of legs (if more than one)

Synthetic Web Sling Requirements

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

Product Spotlight | Crosby Forged Sorting Hooks

Product Spotlight: Crosby Forged Sorting Hooks

Today, the Hercules SLR product spotlight is on Crosby forged sorting hooks. While sorting hooks may not be a piece of rigging equipment the everyday rigger reaches for every day, they are extremely handy when put to use in their intended capacity.

Sorting hooks are manufactured for use in sorting and laying out plates, pipes, cylindrical or tube shapes and other items that allow the full depth of the hook throat to be engaged. They are always used in multiple sling leg applications, in order to balance the load by engaging it on multiple ends.

Although many hooks used in overhead lifting are required to be equipped with a latch, sorting hooks are one of the few types of hooks designed not to use a latch as it would limit the practical use of the hook when lifting plates and cylindrical loads where full throat engagement of the hook is required.

Sorting hooks should be used at a 30° to 45° angle to get full engagement. Since the equipment functionally relies on its long throat being fully engaged, if you fail to do this, it will result in a significant reduction to the working load limit (WLL) of the hook. With this being said, you never want to concentrate your load on the last two inches of the hook tip, as this too would mean the full throat of the hook would not be properly engaged – and that section of the equipment is not made to support significate weight as it tapers off to being much thinner then the weight baring sections of the hook.

Crosby Forged Sorting Hooks are made of forged alloy steel that’s both quenched and tempered. One of Crosby’s many key attributes in that they full-cycle quench and temper heat treatment all of their equipment. In order to properly transform the microstructure of drop forgings (fancy right?!) products are re-heated after forging, then quenched and tempered* using tightly controlled processes and equipment. This heat treatment provides consistent temperature control and results in superior material properties.

*But what in the world is quenching and tempering? The process of quenching or “quench hardening” involves heating the material and then rapidly cooling it to set the components into place as quickly as possible. Tempering is achieved by heating the quenched material below the critical point for a set period of time, then allowing it to cool in still air.

10 Tips From Crosby to Keep In Mind When Using Sorting Hooks

  1. The sorting and laying out process includes moving these materials at a height close to the ground with the load and load connections visually observable by the crane operator throughout the entire load handling activity.
  2. The hooks must be attached in a manner that will maintain a level, balanced and stable condition throughout the entire process.
  3. If the load exhibits obvious bending, the lift must then be immediately stopped for analysis and evaluation to ensure safety.
  4. During the load handling activity, the slings with hooks at the load connections must remain under tension at all times to prevent any of the hooks from disengaging.
  5. Never concentrate loading on the last 2 inches of the hook tip.
  6. Never exceed 45 degrees “included angle” between two sling legs that are on the same side of the load. Exceeding 45 degrees may result in the slings slipping along the load surface.
  7. The recommended angle of loading when using sorting hooks is 30 to 45 degrees. These lower angles, although typically discouraged for most rigging applications, allows the load to more easily obtain full hook throat engagement. When the angle of loading is greater than 45 degrees, tip loading and failure to obtain full hook throat engagement is very much a concern.
  8. Sorting hooks are for straight in-line loading only. Sideloading applications are not allowed.
  9. Calculate the sling tension and know the loading in all connection points to ensure all rigging gear is sized appropriately.
  10. Never exceed the working load limit as stated on the sling identification tag. Remember, sorting hooks are used in multiples, such as two-, three-, or four-leg wire rope sling assemblies. All slings require proper identification including the capacity of the sling assembly.

Bonus Tip!

The real Pelican Hook

Sorting hooks are known as many things, such as lay out hooks, shake out hooks or pelican hooks. Though, if you refer to them as pelican hooks, be sure the person you’re speaking with truly knows what you mean because there is actually a different type of hook used in nautical and marine applications that’s really called a pelican hook. The real pelican hook is meant for securing ship anchors, life raft canisters or cargo gear and they are not rated to perform overhead lifts.

Pssstt…If you’re looking for an actual pelican hook, head on over to Hercules SLR’s sister company, Spartan Marine! Spartan Marine is your source for high-quality marine products and services, offering a wide range of solutions to those with industrial, commercial and recreational marine interests.

Product Spotlight | What are Lifting Clamps?

Product Spotlight: What are Lifting Clamps?

What do you do when you need to lift a beam, pipe or piece of sheet metal with no lifting point? AND you’re told you’re not able to cause any surface damage to the material? Easy—You grab a lifting clamp!

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. When in use, lifting clamps use powerful springs that allow the clamp to essentially become one with the material being lifted (yes, it holds on THAT tight). Most often, lifting clamps are used on sheet, plates or fabrications— Because of this, many people know lifting clamps as ‘plate clamps’ or ‘sheet clamps’.

What are Lifting Clamps? | Types of Lifting Clamps

There are many different types of lifting clamps, but the majority of them fit within two categories—Vertical lifting clamps and horizontal lifting clamps. The following are some examples of lifting clamps sold by Crosby!

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 plate clamp, beam lifting clamp, and drum clamp features a welded alloy steel body that is designed to have high-strength while still being lightweight and compact. Crosby lifting clamps are 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.

Vertical Lifting Clamps

Vertical lifting clamps are used for lifting, turning, moving or vertical transfer of sheet plates, or fabrications from horizontal to vertical and down to horizontal (180 degrees) as need.

  1. The IPU10 has a hinged hoisting eye which allows for the clamp to place and lift the load from any direction, or with a multiple leg sling without side-loading the clamp. The IPU10S is for use with stainless steel and the IPU10H is for use with materials with a surface hardness up to 47Rc (450 HB)
    • Available in capacities of 0.5 through 30 metric tons (higher WLL are available upon request).
    • Wide variety of jaw openings available from 0″ to 6.1″.
  2. The IPNM10N will not mark or scratch the material surface, making it suitable for materials such as aluminum, stainless steel, painted materials, aircraft skins, composite material, glass, and plastic.  The IPNM10P does this while also providing a protective cover that will reduce the risk of damage to surrounding plates.
    • Available in capacities of 0.5, 1 and 2 metric tons.
    • Wide variety of jaw openings available from 0″ to 1.57″.
  3. The IPU10A automatically clicks on to the material as soon as the clamp is placed on the plate. The safety lock will remain in position as the clamp closes precluding hazardous situations. This also allows the clamp to be easily fastened to difficult to reach areas.
    • Available in capacities of 1 and 2 metric tons.
    • Wide variety of jaw openings available from 0″ to 1.97″.

Horizontal Lifting Clamps

Horizontal lifting clamps have a pretension feature that allows users to attach the clamps to the material for horizontal lifting and transfer of non-sagging material. These clamps must be used in pairs or more.

  1. The IPHNM10 may only be used on material surfaces that have no damage and the IPH10 and IPH10E have spring-loaded tension.
    • IPHNM10 and IPH10 are available in capacities of 0.5 through 12 metric tons and IPH10E are 2.0 through 25 metric tons.
    • Jaw openings available from 0″ to 4.75″ (IPH10E only goes to 4.72″)
  2. The IPHOZ is used on thin sheets and other materials that will sag or bend when lifted.
    • Available in capacities of 0.75 through 15 metric tons.
    • Wide variety of jaw openings available from 0″ to 2.36″.
  3. The IPBC has clamps with a pretension feature that allows the user to attach the clamps to sagging and non-sagging materials. These clamps may also be used to handle material that will be used in shears, bending and rolling machines or other fabrication equipment. This clamp may also be used for turning beams from the “H” into the “I” position. IPHGZ and IPHGUZ have these capabilities and may also be used to move and life structural shapes such as I-Beams, H-Beams, etc.
    • Available in capacities of 1 through 4.5 metric tons.
    • Jaw openings available from 0″ to 1.57″.
  4. The IPPE10B(E) is suitable for use on bundles or unbendable sheets of metal. The jaw opening can be easily adjusted for the height of the bundle or the plate. It also has magnets in the footplate, allowing one person to operate multiple clamps at the same time when lifting loads. IPPE10BNM may be used for virtually all applications, where the objects that are being lifted or transported require optimal protection against surface damage.
    • Available in capacities of 3 and 12 metric tons.
    • Wide variety of jaw openings available from 0″ to 7.09″.

Specialized Clamps

Crosby also makes lifting clamps for further specialized uses such as beam lifting clamps, shipbuilding clamps, positioning screw clamps, pipe grabs, beam clamps, concrete road barrier grabs, granite curb grabs, and pipe hooks. If you’re interested in learning more in-depth information about these specialized clamps, email us or call us at 1-877-461-4876.

What are Lifting Clamps? Their Uses

  • The Mining/Quarrying Industry – Many extracting and maneuvering operations use lifting clamps capable of meeting the needs of extreme conditions found in everyday operations within the mining/quarrying industry.
  • Transportation/Towing Industry – Lifting clamps are used in the transportation & towing industry to load vehicles onto trailers, load finished products into containers, and transfer bulky items used in production and construction.
  • Construction Industry – Lifting clamps are on many materials within the construction industry such as fabricated building materials like iron sheets, heavy doors, windows, metals pipes, timber, floors or walls.
  • Steel Industry – You’ll likely find lifting clamps in most foundries and metalworking facilities as lifting clamps are used so much in this industry – The hardware is often known as a ‘plate clamp’ or ‘sheet clamp’ (as we’ve mentioned above), because of its use moving plates of steel.

Lifting Clamp Dos and Don’ts

Based on safety guidelines recommended by the Canadian Centre for Occupational Health and Safety (CCOHS), here are some easy dos and don’t to keep you and your load safe when using a lifting clamp.

DO

  • Select the correct clamp for the job – ensure you’re using the correct clamp for directional lifting (vertical, horizontal or universal) and that the clamp is rated for the thickness and weight of the materials being lifted.
  • Refer to the manufacturers’ operating instructions.
  • Inspect clamps visually before each use.
  • Lift one piece of material at a time unless using clamps and methods approved for otherwise.
  • Use two or more clamps to balance a long or flexible load (always use two or more if manufacture guidelines suggest).
  • Install the clamp(s) over the center of gravity of the load.
  • When using vertical lifting clamps, consider using a locking device to prevent accidental loosening.
  • Always use clamps within their rated capacity and flange width.
  • Ensure clamps are locked in place before lifting a load.
  • Use slings between the clamp and cranes or hoist hooks.
  • Use non-marring (rubber pad) clamps in pairs when lifting finished and polished plates
  • Lift smoothly and avoid jolts.
  • If the use of a tag line is necessary, attach it to the clamp before lifting the plate.

DON’T

  • Do not lift over workers and do not stand near a load – Position yourself away from a fully clear of the load. Remember to also consider how the load might fall when it lands.
  • No not overload or underload a clamp.
  • Do not lift from the side with a vertical-only clamp.
  • Do not attempt to lift materials from the bottom of a stack.
  • Do not drag the load using the lifting clamp.
  • Do not use a clamp having a minimum jaw opening larger than the thickness of the load.
  • Do not leave suspended loads unattended.

Lifting Clamp Inspections

Before using ANY rigging hardware, you should always perform visual inspections to ensure you aren’t using hardware that’s damaged or weakened, making it unsafe to use.

But, keep in mind these quick visual inspections should not and DO NOT replace any required annual inspections. Without inspections and maintenance, equipment failures can have a major effect on safety, unscheduled outages and your business costs. 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. Staying on top of your required annual inspections has never been easier with the Hercules SLR team.

How to visually inspect the exterior of a lifting clamp

  • Always follow the hardware’s manufacturer maintenance recommendations.
  • Inspect internal and external surfaces for forging or weld fractures, wear or distortion.
  • Check all pin holes for wear.
  • Inspect the throat (clamp opening) width – At zero grip, the clamp should be in full contact with the pad.
  • Measure the width of the throat – If the measurement at the base (where the pad is located) is greater than at the top, the body has been overloaded and the clamp and tag need to be replaced.

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.

5 of the Largest and Strongest Cranes

5 of the Largest and Strongest Cranes

5 of the Largest and Strongest Cranes

There are so many types of cranes and crane equipment, which we’ve covered on the blog before—But which types of cranes are the biggest and strongest? Don’t worry, Hercules SLR is here to help.

Read on to discover what some of the mightiest cranes are and what they can do.

1. LTM 11200-9.1

LTM 11200-9.1 crane

Designed by Liebherr, located in Switzerland, the mobile crane, LTM 11200-9.1, is the strongest telescopic mobile crane in the market and offers the world’s longest telescopic boom. It has a maximum lift capacity of 1,200-tons, a maximum hoisting height of 188 meters (616 feet) and a maximum radius of 136 meters (446 feet) – This is over the length of a football field! 

Some of the features found on the LTM 11200-9.1 are:

  • 100m long telescopic boom and 22m telescopic boom extension.
  • Lifting capacity of 65-tons at the 100m long, suspended telescopic boom.
  • 126m long luffing fly jib.
  • 60.5m long fixed jib, optionally hydraulically adjustable.
  • Fast and easy crane assembly with little required space.
  • Active, speed dependent rear-axle steering (all axles can be steered).
  • Economical transportation.

The LTM 11200-9.1 has been used to assemble larger portal cranes, radio towers, absorber columns, and wind power generators. When fully-loaded the base of the vehicle drives with slewing platforms, luffing cylinder and all four folding beams—With all of these elements, it will weigh in at over 100-tons. However, dismantling these elements is easy to do, making it so you only have to travel with what will be used on the job. Doing this can lessen the total weight to 34-tons, making it much more economical to transport.

2. PTC 200 DS PTC 200 DS crane

The PTC 200 DS is owned and operated by a company called Mammoet, located in the Netherlands. This crane is nearly 205 meters (675 feet) tall, has an attachment that can lift 3,500 tons at it’s max capacity and is so large that in order to weigh it down, 35 shipping containers (each 40 feet long) filled with sand are used as counterweights.

This heavy-lift crane has a maximum lift height of 140 meters (459 feet) and a radius of over 136 meters (446 feet). The PTC200 DS can handle a 2,000-ton load at a radius of up to 78 meters with 3,500 tonnes of ballast and 117 meters (383 feet) of boom—Or 58 (190 feet) meters radius on a 140-meter boom. It recently went through an upgrade that allows the crane to lift a 2,000-ton structure in one piece as opposed to lifting it in multiple sections.

The PTC 200 DS heavy-lift crane is used around the world mostly on large refinery and petrochemical projects. The crane was even used to construct the Dubai Observation Wheel, which is the world’s tallest Ferris wheel towering at nearly 213 meters (700 feet) tall. Other than this project, the crane has spent the majority of its life in the United States, South America and here in Canada!

3. The Asian Hercules IIIasian hercules lll 3 crane

The Asian Hercules is one of the world’s largest floating cranes, weighing in at a whopping 16,805-tons. The complete vessel features accommodations for 45 people! With a lifting capacity of 5,000-tons and a maximum lifting height of 120 meters (393 feet), this floating giant is designed for heavy lifting operations offshore.

The Asian Hercules III was constructed in 2015, registered in Singapore and has an ‘ABS A1, + AMS – Heavy Lift Vessel’ classification crane. Among its features, this crane operates with the following winches:

  • 2 cargo winches capable of pulling 20 tons at 10m/min.
  • 2 class anchor winches for handling the 6,975kg HHP bow anchor with a 76 mm grade 3 anchor chain.
  • 2 luffing winches providing a maximum luffing speed of 1.00m/min at full load.
  • 4 main hoisting winches for the A-frame, and 2 for the Jib, each capable of hoisting speeds of 2m/min at full load and 5m/min a light or no load.
  • 2 Jib adjustments winches, mounted on the A-frame, for adjustment of the job without load from 00 to 400 with respect to the A-frame.
  • 2 aux hoisting winches for the A-frame and 1 unit for the Jib, each capable of hoisting speeds of 10m/min at full load of 20 tons.

What’s the Jib? A jib or jib arm is the horizontal or near-horizontal beam used in many types of crane to support the load clear of the main support.

The construction of this mega-crane, designed by Gunnebo, is the culmination of more than 250-years of technical know-how. Designing the vessel required a 5000-ton modular block system with a spreader beam, luffing blocks, and sheaves. After two years of design and construction, the Asian Hercules III is a flexible lifting solution with interchangeable parts that can be customized for different lifting configurations.

4. SGC – 250 sgc-250 crane

The SGC – 250, the Sarens Giant Crane also known as ‘Big Carl’, is a 250,000t/m heavy crane designed to accommodate the heavy lifting requirements for refinery, oil and gas, mining, offshore platform, and third-generation components for nuclear power plants.

Built in 2015, this crane has a maximum lift capacity of 5,000-tons and features a 118m – 160.5m main boom configuration with a 40.5m – 99.5 m heavy-duty jib configuration. It operates on a 48.5m outer ring and requires a 5,200-ton counterweight. The jib can be extended up to 100 meters, giving it a maximum height of 250 meters (820 feet) and radius 275 meters (902 feet).

The SGC – 250 can operate on two different blocks at the same time—One on the main boom and one on the jib. The crane’s main hook block weighs 105 tonnes and has a safe working load (SWL) of 3,200 tonnes while the jib hook weighs 58 tonnes and has an SWL of 1,600 tonnes.

After it’s unveiling the SGC – 250 was transported to the UK where it was used on the Hinkley Point C nuclear power station construction project. Over the course of that project, the SGC lifted more than 600 pieces of pre-fabricated components.

5. SK10,000

SK10,000

Finishing up our list we have a crane that hasn’t yet hit the scene, but when it does, it will take the spot of the world’s largest land-based crane. The SK10,000, created by ALE, is set to be completed by Q4 of 2020.

As floating production storage and offloading (FPSO) units and floating liquefied natural gas (FLNG) units grow in popularity, larger cranes like the SK10,000 become necessary. Often times, modules of these ships are constructed elsewhere and then transferred to the shipyard for assembly. The SK10,000 will allow modules to be installed directly onto the ship’s hulls, advancing current capabilities in terms of both maximum weight lifted and impact on these project’s efficiency.

The SK10,000 will deliver unparalleled lifting capacity as well as a number of other features such as:

  • Jib outreach of up to 200m (655ft).
  • Ground bearing pressure below 25te/m2.
  • A winch hoisting system with various hook blocks to maximize lift capacity and hoisting speed.
  • A small plot area—The design will eliminate the need to install a full ring or crane track unless specifically required for the project, which will reduce the space needed to operate by 45%. This will be ideal for busy shipyards or areas with restricted access like oil refineries or petrochemical plants.
  • Reduced on-site disruption—The large lifting radius will allow the crane to be fully rigged and operated off-plot with less groud preparation needed.
  • Simplified logistics and assembly—ALE‘s specialists will be able to assemble the crane in a matter of weeks using standard plant and a crawler crane.

What’s a crawler crane? A crawler crane has its boom mounted on an undercarriage fitted with a set of crawler tracks that provide both stability and mobility. Crawler cranes range in lifting capacity from 40 to 3,500 short tons.


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?

Industry Highlight | A Look into the Quarry Industry

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.

When it comes to handling heavy materials, it’s important you’re using equipment you can trust to lift the load safely and effectively—That’s where we come in.

CM Guest Blog | The Twenty Year Rule

cm cranes and hoisting equipment

CM ON THE TWENTY YEAR RULE

CM knows it can be easy to fall into the ‘twenty year rule’ trap—but what is it? Read on for tips from Columbus McKinnon (CM) on why some rules actually are made to be broken. 

Their rigging experts discuss safety, inspections & why it’s important to keep your training up to date—No matter how long you’ve been doing it. 

While conducting our overhead lifting safety training it never fails that we get a comment to the effect of,

“We’ve been doing it this way for over twenty years. We never had an accident. And now, you’re telling me it’s wrong?” 

Just because you have been lifting a certain way for the past twenty years and never had an accident only means that you have been lucky. When performing safety training we emphasize all the safety standards and regulations that are applicable. They all serve a purpose.

When performing safety training we emphasize all the safety standards and regulations that are applicable. They all serve a purpose.

ANSI/ASME B30 Safety Standards for overhead lifting began in 1916 as an eight page safety code – now 94 years old. Although ASME is the American Society of Mechanical Engineers, many Canadian organizations and equipment used here observe their standards, so it’s worth noting. 

In Canada, the CSA standard B167.08 began in 1964—It’s 46 years old.

Finally, let us not forget OSHA, which began in 1970, making it 40 years old, who enforces two federal regulations for overhead lifting:  CFR 1910.179 for cranes and 1910.184 for slings. Between all these organizations and safety standards there is a total of 355 years of experience. 355 years trumps your 20 years, every time.

These organizations were not put together to make your life miserable! You can’t take short cuts the way you have been doing the past twenty years. These organizations include people that are involved in all facets of overhead lifting, including riggers and production and construction personnel that perform overhead lifting as part of their job. They want you to be safe in your work habits and environment so that you can go home at the end of your shift or work day to your family.

This blog post was written by Larry Lynn, former Product Trainer for Columbus McKinnon Corporation. 

CM | HOW MUCH IS ENOUGH WHEN IT COMES TO ANNUAL INSPECTION?

So, we know that standards for training, testing & inspections exist for a reason, and it’s important to keep your training and inspection knowledge up-to-date—CM explains more. 

CM was asked, “How do we complete the annual PM (preventative maintenance) per the manual unless we open up the gear box and inspect the internals?” This question is centered around the annual inspection task to inspect ‘Load Bearing Parts.'” 

Tom, a Technical Instructor who specializes in Hoists & Overhead Cranes for the Columbus McKinnon Corporation says: 

We encounter this question frequently in inspection and maintenance training classes. 

ASME Standard B30.16 defines load bearing / load suspension parts as follows; “the load suspension parts of the hoist are the means of suspension (hook or lug), the structure or housing that supports the drum or load sprocket, the drum or load sprocket, the rope or load chain, the sheaves or sprockets, and the load block or hook.”

Brakes, load and holding, gearing, motors, etc. are mechanical parts. They are part of the drive train.

ASME B30.16-2.1.3(b) states, “Covers and other items normally supplied to allow inspection of components should be opened or removed.”

ASME states that required inspection items be prefaced with “Evidence Of.” 

There are several indirect ways of checking for and detecting (finding “evidence of”) excessive wear or abnormal operation of internal parts. If gearbox oil is not degraded, there are no metallic particles attached to the drain plug, the hoist raises and lowers properly (with and without a load), and there are no strange or abnormal sounds from the gearbox, it is unlikely that serious problems exist. If this inspection causes suspicion, refer to ASME B30.16-2.1.3(c) “A designated person shall determine whether conditions found during inspection constitute a hazard and whether disassembly is required.”

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.

Engineer (by Default) Emily Warren Roebling

Brooklyn bridge engineer

Emily Warren Roebling (September 23, 1843 – February 28, 1903) is known for her contribution to the completion of the Brooklyn Bridge after her husband Washington Roebling developed caisson disease (a.k.a. decompression disease). Her husband was a civil engineer and the chief engineer during the construction of the Brooklyn Bridge.

Emily Roebling

Engineer (by Default) Emily Warren Roebling: Early Life

Emily was born to Sylvanus and Phebe Warren at Cold Spring, New York, on September 23, 1843. She was the second youngest of twelve children. Emily’s interest in pursuing education was supported by her older brother Gouverneur K. Warren. The two siblings always held a close relationship. She attended school at the Georgetown Visitation Academy in Washington DC.

In 1864, during the American Civil War, Emily visited her brother, who was commanding the Fifth Army Corps (a.k.a. V Corps), at his headquarters. At a solider’s ball that she attended during the visit, she became acquainted with Washington Roebling, the son of Brooklyn Bridge designer John A. Roebling, who was a civil engineer serving on Gouverneur Warren’s staff. Emily and Washington married in a dual wedding ceremony (alongside another Warren sibling) in Cold Spring on January 18, 1865.

As John Roebling was starting his preliminary work on the Brooklyn Bridge, the newlyweds went to Europe to study the use of caissons for the bridge. In November 1867, Emily gave birth to the couple’s only child, John A. Roebling II, while living in Germany.

Engineer (by Default) Emily Warren Roebling: Brooklyn Bridge

On their return from their European studies, Washington’s father died of tetanus following an accident at the bridge site, and Washington took charge of the Brooklyn Bridge’s construction as chief engineer.  As he immersed himself in the project, Washington developed decompression sickness, which was known at the time as “caisson disease”.  It affected him so badly that he became bed-ridden.

As the only person to visit her husband during his sickness, Emily was to relay information from Washington to his assistants and report the progress of work on the bridge. She developed an extensive knowledge of strength of materials, stress analysis, cable construction, and calculating catenary curves through Washington’s teachings. Emily’s knowledge was complemented by her prior interest in and study of the bridge’s construction upon her husband’s appointment to chief engineer. For the decade after Washington took to his sick bed, Emily’s dedication to the completion of the Brooklyn Bridge was unyielding. She took over much of the chief engineer duties, including day-to-day supervision and project management. Emily and her husband jointly planned the bridge’s continued construction. She dealt with politicians, competing engineers, and all those associated with the work on the bridge to the point where people believed she was behind the bridge’s design.

In 1882, Washington’s title of chief engineer was in jeopardy because of his sickness. In order to allow him to retain his title, Emily went to gatherings of engineers and politicians to defend her husband. To the Roeblings’ relief, the politicians responded well to Emily’s speeches, and Washington was permitted to remain chief engineer of the Brooklyn Bridge.

The Brooklyn Bridge was completed in 1883. In advance of the official opening, carrying a rooster as a sign of victory, Emily Roebling was the first to cross the bridge by carriage. At the opening ceremony, Emily was honored in a speech by Abram Stevens Hewitt, who said that the bridge was

…an everlasting monument to the sacrificing devotion of a woman and of her capacity for that higher education from which she has been too long disbarred.

Upon completion of her work on the Brooklyn Bridge, Emily invested her time in several women’s causes including Committee on Statistics of the New Jersey Board of Lady Managers for the World’s Colombian Exposition, Committee of Sorosis, Daughters of the American Revolution, George Washington Memorial Association, and Evelyn College.  This occurred when the Roebling family moved to Trenton, New Jersey. Emily also participated in social organizations such as the Relief Society during the Spanish–American War. She traveled widely—in 1896 she was presented to Queen Victoria, and she was in Russia for the coronation of Tsar Nicholas II.  She also continued her education and received a law certificate from New York University.

Roebling is also known for an influential essay she authored, “A Wife’s Disabilities,” which won wide acclaim and awards. In the essay, she argued for greater women’s rights and railed against discriminatory practices targeted at women. Until her death on February 28, 1903, she spent her remaining time with her family and kept socially and mentally active.
