Chain Sling Information

Chain Sling Information

Chain slings are used primarily for overhead lifting and are generally used in conjunction with a crane or some type of lifting device. Standard sling configurations consist of chain branches, which are affixed on one end to a master link or ring, with some type of attachment, usually a hook, affixed to the opposite end.

Our Grade 80 chain slings are recommended for use in a industrial environments where flexibility, strength, resistance and long life are required.

Chain Sling Selection

In the case of multi-leg slings, the angle between the legs is critical. The actual tension on each leg increases when the angle between the legs increases as shown in the diagram opposite. For this reason all general purpose chain slings are given a rating based upon use at 90º inc. angle. The included angle between the legs should never exceed 120º.

The distance between the crane hook and the load is known as the “Head Room”. If a specific head room is required, the “Reach” of the chain sling must increase as the angle between the legs increases as shown opposite.

The reach of a chain sling is the distance between bearing points of the upper and lower terminal fittings. This distance, commonly known as the “Bearing to Bearing” should be quoted when ordering slings. Shortening clutches may be fitted to a sling, making the reach adjustable, hence increasing the versatility of the sling.
