Lifting and Rigging Supplies

Working in the lifting and rigging industry requires specific equipment to safely lift, secure, and transport heavy loads. The correct gear must be perfectly matched to the machine and load to avoid any accidents that can hurt people, break merchandise, or damage facilities.

There are many different types of rigging supplies and each has its own set of advantages and applications. This article will explore some of the most common hardware.

Chain Shackles

Rigging equipment is essential for the safe movement of heavy loads. Its use allows companies in industries like construction, manufacturing and transportation to move large-scale fixtures using cranes or hoists. However, different tools have varying functions and must be used in the correct manner.

A chain shackle is a device that connects chains, ropes, slings and other lifting and rigging supplies during the moving process. They are made of loop-shaped steel connected to a chain and contain a safety pin to close them off. There are many types of shackles, and it is important to choose the right one for your project. Some shackles are designed for specific tasks or applications, such as clevis grabs, barrel hooks and sorting hooks.

The type of shackle you choose will depend on the weight and size of the load. The shackle should be rated for that specific load and be able to support the full weight without exceeding its working load limit. You should also check for signs of wear and tear. A worn shackle may cause damage to the load and reduce its overall strength.

Alloy chain is a common choice for rigging applications due to its strength and durability. The type of alloy chain you need depends on the type of application and environment. For example, galvanized and bright chains are suitable for outdoor environments because they withstand corrosion. They are less expensive than stainless-steel options and are easy to clean. In contrast, stainless-steel chains are ideal for indoor environments and can withstand the pressure of high loads.

Eye Bolts

Eye bolts are a secure, versatile and economical option for attaching chains, ropes, cables and other tethering to equipment. These fasteners have a threaded shank on one end that creates a loop for connecting shackles, and they lock in place with a nut. They are available in a range of sizes, shapes and finishes. To preserve their working load limit, inspect eye bolts regularly for signs of wear or deformation and replace them promptly if necessary.

Selecting the right eye bolt depends on the rigging job at hand. For lifting and rigging supplies example, if the eye bolt will be exposed to angular loads, opt for one with a shoulder to provide stability. Choosing the correct eye bolt is also a matter of verifying that its thread size matches the mating nut or hole to ensure proper attachment.

In addition, if the eye bolt will be used in applications where it may be subjected to shock loads, choose one with a built-in swivel. Each swivel ring has a recommended torque value that lets you know how much force is needed to tighten it, helping you avoid over-tightening or stressing the shank. Finally, consider the working load limits specified by the manufacturer of each eye bolt, and always adhere to these guidelines. For more information about safe lifting and rigging, consult resources like OSHA.


Choosing the right sling for a particular load and ensuring that it is properly positioned and secured can greatly increase safety when lifting operations are performed. The weight, shape and nature of the load will influence what type of sling is required to perform the lift safely. The sling must also be compatible with the equipment that will be used for the lift.

Slings are available in a variety of materials including textile (such as polyester, aramid or UHMWPE), rope, metal wire or chain. They can be constructed with eye or sling rings (also known as eyes) at their ends to allow them to be connected to other rigging supplies and hardware such as shackles, hooks and stops. Some slings are designed to be used in conjunction with a block and pulley system.

Wire rope slings consist of individual steel wires that are twisted together into strands and braided around a core material. They are available with a range of end connections and are categorised according to their design, working load limit (WLL) and application.

During the launch of SpaceX’s crew capsule, a sling was used to get it out of the ocean and onto the ship for recovery. Slings are also used for a huge range of tasks such as installing solar panels on buildings, delivering and lifting wind turbines and transporting cargo containers aboard ships, trains and container lorries.


Anchors serve as connection points for lifelines and lanyards used to support workers who are working at height. Ensure the anchors you use are compatible with your fall protection system and meet the recommended Working Load Limit (WLL) of your system.

They’re also an integral part of permanent and semi-permanent mooring systems. Large ship anchors get their holding power from the mass of their body and by “hooking” into the seabed or embedding in it. Modern anchors for smaller vessels use metal flukes to hook onto rock or bury themselves in the seabed.

Different anchor types serve specific conditions and purposes. Claw-type anchors have difficulty lifting and rigging supplies penetrating weedy or grassy bottoms. They’re also over-sized for their rode scope and have low efficiency, but they do offer good holding power for their weight.

Other anchors for rigging include ring type and d-ring bolts. These use a cotter pin to eliminate the need for pre-lift inspection and tightening of the bolt. Bolt-type shackles have a threaded pin that can be tightened or removed and are practical for many applications, but they’re not as efficient as other anchors. For semi-permanent and long-term installations, round pin shackles are more effective.
