What is a Chain Sling ?
H-Lift Grade 80 Chain Sling, Lifting Sling:
H-Lift Grade 80 chain slings and lifting slings are ideal for applications when extra strength and durability is required. Not only are chain slings more durable, temperature-tolerant, and cut-resistant than polyester webbig slings or round slings, there are also adjustable and customized options.
In this 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 90° inc. angle. The included angle between the legs should never exceed 120°.
The distance between the crane hook and the load is known as the “headroom”. If a specific headroom 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. 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, hence increasing the versatility of the sling.
