Do You Have the Right Set of Equipment for Your Rigging Operations?

Rigging is often used with cranes in construction projects. It refers to the whole setup of equipment such as turnbuckles and wire ropes used to move loads from one point to the other. Often, rigging will go hand in hand with slinging, which describes the actual movement of the load as it hangs suspended on the crane. Both terms give the illusion of a straightforward process, but there is a lot more to it. Rigging requires a thorough understanding of the safe operation of all the equipment involved. The following piece outlines the rigging tools you will need and the task performed by each:

Synthetic Slings

Synthetic slings are a common feature in many rigging operations. Web slings are a preferred option because of their extreme versatility. Essentially, the synthetic web slings offer strength for supporting heavy loads with smooth edges that allow handling delicate materials. The soft surface is better than that found on traditional wire ropes.

Note that synthetic web slings can be made using nylon or polyester. You can also go for lightweight, high-performance materials that are extremely flexible and easy to rig. Ensure that a professional inspect these slings often for signs of degradation and damage by weather elements.

Outrigger Legs and Pads

You will also need outrigger legs and pads for a smooth rigging operation. Then outrigger legs offer additional support to the crane. They are also called stabilisers. In most cases, they come as retractable hydraulic legs extending from the crane's structure to the ground. You can opt for an H-style shape with a pair of round or square legs attached to the end of an extendable horizontal frame. The other option is an A-style shape with legs extending at an angle.

Outrigger pads are special platforms made from recycled materials such as polyethylene. They are used to hold outrigger legs in cases where the site conditions elevate the risk of an unstable crane setup.

Lifting Chains

Lifting chains are instrumental for securing and lifting the load. Some of the considerations here include the number and diameter of chains. They vary according to the load in question. The weight limit also plays a part. High-quality steel chains have a higher weight limit and a better chance of handling heavy loads with minimal damage. Steel chain grades will vary from grade 30 to grade 120. Therefore, work closely with a qualified rigger to ensure the best outcome.
