GRADE 80 CHAIN SLING AND ITS FITTINGS

Grade 80 alloy chain slings are often selected when operating under high temperature or rigged conditions that would abrade or destroy other types of slings. They are flexible, durable, long lasting, ductile, easy to inspect, collapsible for convenient storage, and will adhere securely to the contours of a load. The most advantageous feature of a chain sling is its ability to be repaired/ Nearly any damaged component discovered during an inspection can be repaired and restores to useful condition。

Load Estimation

In 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 900 inc angle. The included angle between the legs should never exceed 1200.

Headroom

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

Reach or Effective Working Length (EWL)

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 Effective Working Length 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.
　
　

Uniform Load Method of Rating

All general purpose slings should berated by the uniform load method as shown in the table below.
