Types of Rigging Supplies
Rigging supplies are critical for workers to lift heavy loads safely. There are many different types of rigging equipment that are suitable for specific jobs and weather conditions.
For example, slings can be made of synthetic materials or rigid ones, and the material will determine the tensile strength. Another essential piece of rigging equipment is the spreader bar, which helps to distribute the load evenly.
Wire ropes
Wire ropes are an important part of the rigging industry. They are used to lift and hoist heavy loads, such as machinery. They also support mechanical power transmission. They are typically made of stainless steel or galvanized metal and have a high degree of strength, flexibility, and abrasion resistance.
There are many different types of wire ropes, and each one has its own set of specifications. Some of the most important specifications are the number of strands, size, and strand pattern. It is also important to consider the amount of load a particular rope can carry and its length.
A wire rope is a heavy-duty cable with several wires in a specified pattern that surrounds a central core. Its design allows for internal movement and adjustment of the wires rigging supplies as it bends. It is used in a variety of applications, from cable cars to ski lifts. It is also often used in the live theater industry to raise and lower curtains and hold backdrops and scenery pieces during a production. To ensure that wire ropes are safe for use, it is important to inspect them regularly. Inspections should include checking for kinks, abrasions, lack of lubrication, crushing, reduction in diameter, and stretch.
Shackles
Shackles are the hardware links that connect the rest of a rigging system together. They are available in a variety of styles and sizes to meet different needs. When choosing a shackle, consider the country of manufacture, the diameter, and the working load limit (WLL). A shackle with an inadequate WLL could be a safety hazard, so it’s important to make sure that it can handle the load you’re lifting.
Whether you’re looking for nylon slings or polyester round slings, there are many options for every job. Each type of sling offers unique benefits for your rig, so you can choose the one that works best for your specific application.
Sorting hooks are designed to lay out or sort flat metal plates, pipes and other tube-shaped objects. They are used in conjunction with a multi-leg bridle sling assembly and must be utilized at 30-45deg sling angles. They have a wide end point that goes under the lip of a barrel or drum. Positioning swivel hooks are designed to swivel to allow the rigger to position the hook while connecting it to the load.
Eyebolts
Eye bolts are one of the most versatile types of rigging hardware. They consist of a threaded shank and an eye at the end, and can be used to attach slings and other equipment. However, they are often misunderstood and misused. When used improperly, they can result in dangerous accidents.
When selecting eye bolts, consider their load capacity and the material they’re made from. Stainless steel is ideal for use in harsh environments because it retains its corrosion resistance even when scratched or dinged. Another good option is galvanized eye bolts, which have a thin coating of zinc that protects the metal from moisture and environmental elements.
It’s also important to consider the shoulder design of the eye bolt, which is where the eye and shank converge. The working load limit (WLL) of a shoulder eye bolt is calculated for a straight-line pull, but the WLL decreases as angular loads increase. For this reason, you should always use swivel hoist rings for angled lifts. They will adjust to any sling angle and maintain 100 percent of the bolt’s rated capacity.
Steel nuts
Stainless steel nuts are used in various applications and industries to create secure and dependable connections. These fasteners are able to withstand high stresses and loads. These nuts are also available in a variety of sizes and grades. They are often plated or coated to increase their corrosion resistance. They are commonly used in conjunction with stainless steel bolts and screws.
Rigging hardware is also useful in other recreational activities, such as rock climbing and water skiing. Bolt snaps and D-rings are rigging equipment that can be used to anchor equipment in these situations. These rigging equipment also reduces the amount of force that is needed to support heavy loads.
Another common type of rigging hardware is the block and pulley. These pieces of equipment are designed to reduce the kind of force that is needed to lift an exceptionally heavy load. This is achieved by reducing the number of turns and increasing the sheave size. The most common types of blocks and pulleys include snatch blocks, swivel blocks and square blocks.
Rigging hooks
There are many different types of rigging hooks, and each one has a specific purpose. Some are designed with safety latches to help guarantee that the sling is firmly attached. Others are meant to be used in particular environments or with certain kinds of slings. It rigging supplies is important to choose the right hook for a job and use it correctly. Never exceed the hook’s Working Load Limit, tip load it, or overload it with chains or attachments.
Positioning swivel hooks allow the rigger to rotate the hook for positioning before connecting it to a load. However, they are not designed to swivel while loaded. True swivel hooks with bearings, on the other hand, are designed to swivel 360 degrees while loaded. They are also a great choice for applications that require swiveling hooks that won’t twist during hoisting.
Foundry hooks have wide and deep throats that fit trunnions, handles, and other closed fittings used in foundries. These hooks are designed without a safety latch and are used in environments where it would be unsafe for workers to connect or remove them.
