Chain Slings
All our chain slings are available in single or multiple leg with various hooks, shackles and shorteners depending on your application.
Material / Design: In the manufacturing of chain slings, grade 8, 10 or 12 short link chain should be used. In multi-leg slings the chain dimension and grade must be the same for each leg. The working load limit for assembled components must be at least the same as the working load limit for the current chain. A Master link with an intermediate link should always be used for 3 and 4 leg slings.

The ‘reach’ of a chain sling is the distance between bearing points of the upper and lower terminal fittings.The 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 and increasing the versatility of the sling.
A 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 the angle between the legs increases as shown below.
In the case of multi-leg slings, the angle between the legs is critical. The actual tension on each leg increases as shown in the diagram to the left. For this reason all general purpose chain slings are given a rating based upon use at a range of angles up to 45 degrees to the vertical.A reduced rating is also given for use in the range of angles between 45 and 60 degrees. Chain slings should never be used at angles greater than 60 degrees to vertical.
