Lifting and Rigging Supplies

Rigging supplies are tools that connect chains, ropes and slings to each other or a load. They can also help stabilize hefty materials during the lifting process. These tools include choker, eye, sorting and clevis grab hooks. They come in different sizes, and their throat — or hook opening size — depends on the materials being lifted.

Wire rope

Wire rope is used in a wide variety of applications, including cranes, mooring lines, drill lines and hoist lines. It can withstand crushing, bending and abrasion, making it ideal for use in engineering and heavy-duty construction applications. It is also used for cable roofing and safety fences.

There are several variations of wire ropes, which are based on the construction process and materials used to configure and construct them. Stainless steel and galvanized carbon wires are common choices with aluminum, nickel alloy, bronze, copper and titanium being alternative options.

The most important factor is the core, which supports and stabilizes the strands of wire. The core can be made from a range of materials, including natural or synthetic fibers and steel. A steel core can offer better levels of resistance to flattening, crushing and deformation. In addition, a steel core can be more tolerant of corrosive environments than a fiber core.

Lifting beams

Lifting beams are below the hook lifting devices used to handle a load that can’t be lifted with a single crane hoist’s hook. They are designed to equilibrate the weight of the load so that it can be safely lifted. They come in different shapes and sizes and are made of metal in many alloys. The most basic lifting beam consists of a slab of metal with a single attaching point in the center where the crane hook and slings will be attached.

They can also have a number of additional lifting points on the underside. These can be used to connect the load to the beam with shackles and other rigging attachments. They are often used for shorter span lifts that don’t require a large amount of headroom and can help with loads that have flexible materials like thin metal sheets or steel plates.

Spreader bars

Spreader bars distribute a load over more than one point, increasing stability and minimizing the risk of an accident. They are often used with wire rope slings and are available in various lengths. They can also be used to lift coils or other horizontal materials. These below-the-hook lifting devices are commonly used for crane, rigging and transport work, especially when there is limited headroom clearance.

A typical spreader bar consists of a fixed or adjustable length of powder-coated rectangular structural steel tubing with swivel hooks on each end. hand pallet Some have a single center attachment point for added stability.

Before using a spreader bar, it should be visually inspected by a designated individual. The device should be free of defects and capable of handling the rated load. A bar that isn’t safe to use should be marked “out of service.” The designated person must consult the manual for assembling, adaptor attachment guides, rigging requirements and more.

Pulleys and blocks

Pulleys are essential for lifting very heavy weights because they reduce the amount of force that is required. They can be used alone or in conjunction with a spreader bar to distribute the load across multiple connection points and create more stable lifts. These devices are also a staple for moving hefty objects and can be used to move anything from a truck to a building.

Snatch blocks are often used to redirect a wire rope or chain in order to make it easier to winch and lift heavy equipment. They are usually made of steel and other corrosion-resistant materials and can handle a large amount of weight.

They are available in single and double-sheave systems with a variety of different options for bearing parameters, such as shaft diameter, sheave OD, angular contact angle, working load limit, and more. They are designed to work with both steel and synthetic wires, and can be ordered in a wide variety of sizes.

Eye bolts

Eye bolts are used to create secure anchor points for lifting slings, wire ropes, and other rigging hardware. They can withstand high-tension forces without compromising the load. They are also easy to install. However, you should always check the safe working load (WLL) of your eye bolt before using it for a lift.

You can use forged or non-forged eye bolts for your rigging applications. Forged bolts feature a forged eye that adds strength and prevents the screw thread lifting equipment manufacturer from bending. Non-forged eye bolts, on the other hand, have a bent eye that could open under stress. They are best used for through-hole lashing and suspension applications within the WLL.

For angular loading, choose shoulder eye bolts. The shoulder design reduces the tension forces on the shank, making them suitable for angled lifting and rigging. You can also opt for galvanized eye bolts that retain their corrosion resistance when exposed to moisture.

Eye nuts

There is a wide variety of hardware used in the rigging industry. Some of this hardware includes shackles, hoist rings, and eye bolts. These devices are used to create a secure anchor point for ropes and slings to pass through or attach to. They are essential in overhead lifting applications, but improper use of these devices increases the risk of equipment damage and serious injury.

When choosing an eye bolt, be sure to select the correct size based on type and working load limit. The bolt should also be inspected and cleaned before using it for any lifting application. It is recommended that washers be packed between the eye bolt and a load to avoid bending. Shouldered eye bolts should be used for angled lifts, as they are more resistant to bending. If you need to use a standard bolt for angled loading, it is recommended that you choose one with a swivel hoist ring.
