Product Spotlight | Crosby Shackles

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

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

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

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

Anchor Shackles

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

Wide Body Shackles

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

Chain Shackles

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

Theatrical Shackles

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

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

Remotely Operated Vehicle (ROV) Shackles

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

Shackle Variations

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

Screw pin shackles

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

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

Round Pin shackles

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

Bolt Type Shackles

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

How to Choose a Shackle?

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

7 Quick Tips For Using Shackles

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

Product Spotlight | Lifting Magnets

Product Spotlight: Lifting Magnets

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

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

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

Types of Lifting Magnets

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

Permanent Magnets

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

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

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

Electromagnets

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

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

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

The Advantages of Lifting Magnets

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

And this is how…

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

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

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

5 Things to Keep in Mind When Using Lifting Magnets

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

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

1. Air Gaps

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

2. Magnet Contact to Surface 

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

3. Material Being Lifted

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

The lifting force percentage of various materials:

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

4. Bending of the Load

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

5. Thickness of the Load

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


Hercules SLR makes lifting magnets for a wide range of applications using permanent, electro-permanent, battery-powered, and electromagnetic technologies. Lifting Magnets are versatile, compact, easy to operate and can be used on flat and round material ranging from 0 to 11,000lbs. Our larger lifting magnets are designed for applications such as handling billets, bundles, bar stock, slabs, plates, structurals, long bar stock, rail, hot material, coils, pipe rebar, radioactive material, slag, and more.

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.
