WHAT IS A CHAIN SLING AND WHAT ARE ITS PARTS?

At its most basic, a chain sling is chain lifting equipment composed of metal chains, usually made of steel. The chain sling is then connected to a crane as part of its hoisting mechanism. The end of the chain rigging has a sling hook that is latched onto the load which is being lifted or moved.

CHAIN RIGGING COMPONENTS?

Chain slings come with over one chain and referred to as ‘legs’. When there is over one leg, the part of the chain connected to the hoist mechanism is the Master Link. It then connects to the Master Coupling Link per leg, which connects to a coupling link per leg. All this might seem like overkill, but it is for the sake of safety and increased tensile strength.

The chain links to the last Coupling Link which connects to whatever lower fittings are necessary to lift the load. These lower fittings change as per the load being lifted. The ‘reach’ of the chain is the length from the curve of the lower fitting up to the Master Link added to the full height of the Master Link.

4 CHAIN SLING TYPES YOU CAN FIND IN INDUSTRIAL USE

There are 4 distinct chain sling types in use. A short link chain is the most common. People use long links for lashing. Calibrated chains are used with chain blocks, and stud chains in anchor handling for ships.

There are 2 broad categories of chains. Welded, non-graded chains, and weldless chains. Many chain types fall into these categories and depending on applicability, you might come across them in your life.

For industries where heavy loads are lifted; the most common welded, non-graded chain is the passing link chain, with wide link design. This enables links to pass each other without restriction, minimising tangling and kinking.

For weldless chains, you are likely to encounter a steel sash chain. It’s a flat metal chain suitable for industrial assemblies. With a stamped, flat link that can operate smoothly over pulleys, it’s designed for optimal counter-balancing.

We recommend that all businesses use a Grade 80 or Grade 100 stainless steel or alloy chain slings for lifting. These chains have high tensile strength and are heat-treated for optimal operation.

THE DIFFERENCE BETWEEN CHAIN LIFTING SLINGS AND CHAIN BLOCKS? 

A chain block is part of the main lifting apparatus. It’s where the chain passes as the load is lifted or lowered. Whereas, a chain sling is an extra lifting attachment that is added to the end of the chain to help in load balancing.

Chain slings aren’t the only lifting tackle available. A modern equal to chain slings, which some might prefer because of ease of storage, is a nylon sling. The tensile strength of a nylon sling comes from how many plies it has. So one-ply nylon sling will lift less than four-ply.

ARE LIFTING CHAINS AND HOOKS SAFE?

Chain lifting equipment has different grades in relation to the chain itself. Grades 30, 40, 60, and 70 are not suitable for lifting.

Grade 80 is suitable for lifting and in fact, it is the most common chain grade for manual lifting. It’s used for slings, magnets, heavy-duty dragging, and pulling.

Grade 100 chains are approximately 25% stronger than Grade 80 chains and also approved for lifting.

Also remember that the more chain legs you add, the more you increase the tensile strength in proportion. A 4-leg chain sling will lift a higher load than a 2-leg chain sling. For the best safety, always have components able to lift more than your average load value.

Types of hooks offered include ratchet binder, lever binder, turnbuckle, clevis slip hooks, and clevis grab hooks.
