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. These are used when there are especially heavy loads or when the sling will be subjected to heat that would damage the core of a wire rope or the synthetic material in a web sling. These are used less often on most construction jobs, because they are heavy and the chain links may damage the load.
Chain Wrenches feature a chain. This type of wrench is used when a strap wrench slips or when the surface of the shaft does not need to be smooth. The chain wrench marks the surface on which is used. Uses a 15″ or 20″ chain, along with a double-jaw wrench, providing ratchet like action in either direction. Chain wrenches are used by wrapping the chain around a length of pipe and engaging the sprockets in notches on back of the handle.
