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.

Rigging in Space | SpaceX Uses Crosby 

Rigging in Space: SpaceX Uses Crosby 

Rocket science—Pushing the boundaries between new technology and old technology.

Whether you’re familiar with the ins and outs of rocket science or not, you probably have some idea of its complexity. Rocket science has even become slang for anything overly complex, detailed or confusing—With “It’s not rocket science” becoming a popular way of saying that something isn’t very complex.

But, did you know that even the rocket science industry depends on rigging hardware and technology in order to successfully see their work come to life?

SpaceX, Elon Musk’s Company, has gained worldwide attention for a series of historic milestones. It’s the only private company that has returned a spacecraft from low Earth orbit, which it first accomplished in 2010. The company made history again in 2012 when their Dragon spacecraft became the first commercial spacecraft to deliver cargo to the International Space Station.

Even a record-breaking company like SpaceX relies on the tried and true technology of rigging. Crosby wide body shackles were used on the recent SpaceX Starship lift near Brownsville, TX, to join the two halves of the spacecraft together.

SpaceX operates the world’s only operational reusable orbital-class rockets and spacecraft designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Once complete, this star-ship will be the world’s most powerful launch vehicle ever developed. It will have the ability to carry in excess of 100 metric tonnes into Earth’s orbit.

Unfortunately that prototype, the Starship MK1, partially exploded during a pressurized test conducted by the SpaceX team late last month. It erupted at its tip, sending vapor and shrapnel flying into the air—You can check out the explosion here, captured on YouTube.

However, as stated by SpaceX a few hours following the test, “The purpose of today’s test was to pressurize systems to the max, so the outcome was not completely unexpected…There were no injuries, nor is this a serious setback.”

They’re wasting no time jumping into the next model, the Mk3, so there will surely be lots of record-breaking updates to come in this saga of futuristic space exploration!


Nobody knows what the future of space exploration holds—But something we can always be sure about is Crosby. The Crosby brand has been trusted for more than 130 years as the world’s leading manufacturer for rigging, lifting, and material handling applications.

Crosby delivers the industry’s most comprehensive portfolio of products, engineered to exceed the toughest demands—Even when faced with lifting a SPACESHIP!

What You Get When You Buy Crosby Rigging Equipment

Have you ever considered where your Crosby rigging and lifting equipment and hardware comes from?

The hooks, shackles, chain, and other rigging accessories you use on the job, and trust to keep you and your load safe, began as simple, raw materials. These raw materials were then forged, assembled and finished into the final product that you buy from rigging shops like Hercules SLR.

Curious about your rigging equipment’s journey from manufacturing to your hands? With Crosby’s Vertically Integrated Supply Chain, you know exactly where the raw materials used to create your rigging hardware originate and where the product is manufactured.

WHAT MAKES CROSBY’S SUPPLY CHAIN SO SPECIAL?

Check out the video below and learn what sets Crosby’s vertically-integrated supply chain apart.

Crosby Rigging Equipment: Key Attributes

Why choose Crosby rigging equipment? Here are some of the characteristics you’re guaranteed to get when you buy Crosby rigging and lifting equipment.

Drop forge Manufacturing: Crosby operates on an over 100 year proven process of forming heated steel bars into fished shapes through compression forces. This provides desirable material properties and efficient shapes for superior product performance.

Job-ready Markings: All Crosby materials feature raised lettering showing the brand, working load limit (WLL), and angle indicators to ensure you are able to choose the proper product is easily identified prior to every lift. This will help costumers avoid incorrect product selection or determination of load angles, which can lead to overloading, and serious safety hazards.

Full-cycle Quench and Temper Heat Treatment: In order to properly transform the micro-structure 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 to below the critical point for a set period of time, then allowing it to cool in still air.

Material Performance: Strength, ductility, fatigue, resistance, and toughness are four highly important material characteristics that are necessary for safe lifting. Each of these things are verified through rigorous testing to reflect how the product will perform in the field. All Crosby drop-forged hardware exceeds these necessary requirements which means they:

  • will always meet load rating,
  • deform when overloaded for visual indication,
  • are suitable for continuous use,
  • have improved resistance to fracturing.

Crosby qualified distributor network: Hercules SLR is proud to be a Crosby qualified distributor. All distributors are selected through a rigorous verification process and only distributors with deep knowledge and capability in lifting and rigging are chosen. Hercules SLR will make sure you get the right equipment at the right time with unparalleled support prior, during, and after your lift.

So, What is a Vertically Integrated Supply Chain?

When someone says “vertically integrated supply chain” they essentially mean that the supply chain is owned by the brand that produces the product. This means that the product you purchase was manufactured by the brand itself, by their employees and in warehouses they own—Rather than outsourcing that labor to a manufacturer.

While it’s not necessarily unusual or poor practice to outsource labor to manufacturers, it does require companies to be a bit more diligent to ensure the product they receive has been manufactured to the quality they expect and need—Vertically integrated supply chains cut out that extra step. It allows for full control of the process from raw materials to finished goods, ensuring a high level of quality and consistency due to multiple inspections.

Some key benefits that come with vertically integrated supply chains are:

  • Control over the supply chain and the quality of raw materials.
  • Control over the production scheduling and the manufacturing process.
  • Internal responsibility for the quality and safety of products.
  • No reliance on suppliers – Allows brands to avoid supply disruption.
  • More cost control.

Crosby Guest Blog: Shackle Inspection & Care

crosby shackles

CROSBY SHACKLES 

Crosby shackles are a popular option for lifting applications. Time-tested and work proven, Crosby has made their mark in rigging—they’ve produced the first wire rope clip, quench and temper fittings (this makes performance more reliable) and were the first to fatigue-rate products. Their shackles are particularly popular – read on to learn more about Crosby shackles and how to use them safely, a handy interactive inspection checklist and more tips for best use. 

CROSBY SHACKLES: 3 MAIN SHACKLE TYPES

Round pin shackles can be used for lifting applications and others like tie down, towing or suspension applications when the load’s strictly applied in-line.

Screw pin shackles are used for pick and place applications. Pick and place applications are when a load is moved to its desired location, and the screw pin is tightened before each pick.

Bolt-type shackles can be used in any applications that round pin or screw pin shackles are used. They’re also great for long-term or permanent installations where the load may slide on the pin, which causes it to rotate. The other way to secure a shackle includes using a nut and cotter, which eliminates the need for you to tighten the pin before each lift or movement. 

CROSBY SHACKLES: USE THEM SAFELY  

Before you put your Crosby shackle in service, make sure your shackle’s in good condition. To do so, look for these conditions:

  • The shackle’s pin works freely and fits correctly. 
  • The pins are undamaged, have no considerable wear and fit properly from the opposite side of the shackle. 
  • The load line and jaw opening are aligned.
  • The pin is always seated and is ‘matched’ to the body.
  • The shackle is the right material, size and type for the proposed lift.
  • Shackles are stored in a dry, cool place.

CROSBY SHACKLES: INSPECTION 

It’s important to inspect your rigging equipment frequently. Ideally, this happens before use, during (check for points of stress or tension during use) and after use. Inspection is important to prevent equipment failure, which can lead to damaging the load entirely, or worse—injure or kill workers’. 

Check your shackle before use. If any of these conditions are present, remove your shackle from service and have it inspected, repaired or replaced. 

  • The shackle’s jaws or pins are distorted.
  • The shackle isn’t stamped with is safe-working load (SWL).
  • The shackle is home-made (never use homemade shackles).
  • The shackle’s pin does not work freely, or fit correctly in the shackle’s opening. 
  • The pins’ threads are damaged, worn down or don’t easily screw in from the opposite side of the shackle. 
  • The unthreaded hole is enlarged – a hole too big places unnecessary strain on the loaded shackle. 
  • The shackle has wear that’s reduced its diameter by more than 8% of its original diameter. To test for cracks that may be hidden, tap them with a hammer. A shackle in good-condition should ‘ring’ clearly.
  • The shackle’s pin has been replaced, especially if it’s been replaced with anything but a pin. 

CROSBY SHACKLES: USE THEM SAFELY OR NOT AT ALL 

There are a few things to keep in mind when using shackles for securing and lifting applications. 

  • When you use shackles in conjunction with multi-leg slings, you must give consideration to the angle between the legs of the sling. 
  • As the angle increases, so does the load in the sling leg, and as a consequence, any shackle attached to the leg. 
  • Try to avoid erratic loading of the shackle – to do this, place a loose spacer on either end of the shackle’s pin, or use a shackle with a smaller jaw. 
  • If using a shackle to secure the top block of a rope block set, the load on the shackle is increased by the value of the hoisting effort. 
  • Take care to make sure the shackle and assembly above the hook is the right capacity. 
  • It’s important that on shackles fitted with a nut and bolt pin, the length of the bolt’s plain portion will cause the nut to jam on the inner end of the thread, and not on the shackle’s eye. This leaves the bolt free to rotate.
  • Be sure the bolt and nut are cross-drilled for the fitting of a split cotter pin.

Guest Blog: Crosby Talks Forged Wire Rope Clips VS. Malleable Cast Iron Clips

crosby wire rope clips at hercules slr

FORGED STEEL WIRE ROPE CLIPS VS. MALLEABLE CAST IRON CLIPS

What’s the difference between wire rope clips? Guest blogger Danny Bishop, Director of Training for Crosby stopped by Hercules SLR is here to share some information about the difference between malleable cast iron and forged U-Bolt clips.

Read on to discover his expert tips for rigging with U-Bolts. 

 

crosby rigging, hercules slr

 

 

 

 

 

 

 

U-Bolt style wire rope clips are one of the most commonly used accessories in the world of rigging. They can be found in many lifting and non-lifting applications.

Some common applications include winch lines, crane hoist lines, suspension cables, barrier cables, guy wires and many more applications. However, it is critical that the user know there are differences between a forged steel wire rope clip and a malleable cast iron clip.

The forged steel wire rope clip consists of a U-Bolt, two nuts and a forged steel base, which is sometimes called the saddle.

The malleable cast iron U-Bolt style wire rope clip consists of the same components as just mentioned except the clip base is NOT forged steel. In fact, it is a malleable cast iron, and that can make a big difference in the performance and reliability of the clip. The malleable cast iron base does not have the desirable material properties of steel, or the beneficial grain structure that a forged base provides. Although, malleable cast iron products have their place in industry, it is not the manufacturing process of choice for wire rope clip bases. This is especially true if the wire rope clip could be used in a critical application.

Notice that some standards do not allow the use of malleable cast iron clips in critical applications. One example would be ASME B30.5 which states that “Wire Rope Clips shall be drop-forged steel of single saddle (U-Bolt) or double saddle clip. Malleable cast iron clips shall not be used. “ASME B30.26 also states: “Saddles shall be forged steel.”

Additionally, shortcuts in the production process of the bases may also indicate there could be other shortcomings of the product. In some recent testing of malleable cast iron clips, it was found that U-Bolts fractured prior to achieving the recommended forged U-Bolt Clip torque, on 2/3 of the assemblies tested. (See picture of test mentioned).

Also consider:

  • Malleable Cast Iron Clip bases are significantly different from forged bases in size, shape and appearance. See figure 1 to compare a Crosby forged clip base and a Malleable Cast Iron clip, both for ½” wire rope. 
  • Malleable Cast Iron bases are inconsistent in strength, and can have hidden defects. 
  • Malleable Cast Iron clips should not be used for critical applications.

Note the significant difference in size, shape and appearance even though both are 1/2″ diameter for wire rope. Also, the Crosby clip exceeds ASME B30.26 marking requirements. No readable markings were found on the malleable cast iron clip.

Crane Operator Crushed Between Two Steel Frames When Rigging Failed

The operator of an overhead crane had been using a chain sling attached to the hook of the crane, and was setting it up into a single choker hitch to pick up and turn over the steel frame, that was lying horizontally on two sawhorses. The hook on the sling did not have a safety latch. The operator was standing between the load and another steel frame that was leaning vertically against the shop platform. The chain disconnected from the hook and the vertical steel frame fell towards him. He was crushed between the two steel frames. [Source: OSHA Case Histories – Rigging Accidents- Case History #7]

Possible ways to prevent this type of accident:

  • Ensure that workers do not place any part of their bodies into areas where they might become trapped when operating an overhead crane.
  • Ensure that the tools and equipment used are regularly inspected for defects and are replaced or repaired as needed.
  • Ensure that workers who use cranes are trained in rigging procedures.
  • Perform daily inspection of cranes using safety checklists to ensure that all equipment is working properly.
  • Ensure that the hook has a working safety latchand if not, is moused.

Invest in tomorrow by practicing safety today! There are several organizations that are dedicated to maintaining and progressing safety standards. ASME has sustained safety standards for the Crane, Rigging, and Lifting industry. One of the most frequently referenced standards is ASME’s B30 Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings.

ASME B30 is referenced throughout Crosby literature and training material. The many volumes cover a wide variety of topics, but there is a consistency to the guidance offered. For example, latches are discussed repeatedly appearing in B30.2 (Overhead Cranes), B30.5 (Mobile Cranes), B30.10 (Hooks), B30.23 (Personnel Lifting), and others.

When it comes to the use of latches, B30.16 (Overhead Hoists) summarizes it perfectly:
“Hooks shall be equipped with latches unless use of the latch creates a hazardous condition.”
