What is alloy chain slings ?

When it comes to toughness and dependability—alloy chain slings are the bulldogs of lifting slings. Chain slings can be used to lift very heavy and bulky loads on a regular or repetitive basis. Their flexible design provides strength and durability so they can withstand impact, extreme temperatures, and exposure to chemicals and UV rays.

Chain slings are preferred in high-temperature applications and for lifting heavy-duty loads. Their strength and durability allow them to be used in foundries, steel mills, heavy machine shops, and any other environment where repetitive lifts or harsh conditions would damage or destroy a wire rope sling or synthetic nylon or polyester sling. If any damage does occur on a chain sling, they are completely repairable and can be load tested-and re-certified after the repair.

Alloy chain slings can be heated up to temperatures of 1000°F, however the Working Load Limit must be reduced in accordance with the manufacturer’s recommendations when continually exposed to temperatures above 400°F.

Chain slings can be configured in single-leg, 2-leg, 3-leg, and 4-leg designs. They can be configured for use in vertical, choker, or basket hitches and a variety of different sling hooks, lengths of chain, and master links can be used to create different sling assemblies for different applications.

While there are many different types of chain, alloy steel grades 63, 80, and 100 are normally recommended for overhead lifting. In some applications, chain slings made of material other than alloy steel may be used. These applications involve a corrosive or high-temperature environment. The chain material in these unique applications is often stainless steel or some other special material chain. If non-alloy chain is used for lifting, we recommend that the user document the reason for using chain other than alloy, and also follow all appropriate chain sling standards including sling identification and inspection.

The Design Factor for chain slings is a 4:1 ratio, meaning the breaking strength of the sling is four times higher than the rated Working Load Limit. Although chain slings have a design factor, the user should never exceed the rated Working Load Limit.
