Abstract:
A hoist security arrangement for avoiding dropping of the load when the chain or cable breaks includes a longer redundant auxiliary chain or cable disposed alongside the main chain or cable and which is raised and lowered synchronously with the slightly shorter main chain or cable so that the main chain or cable normally supports the entire weight of the load. If the main chain or cable breaks, the load drops slightly until the slack in the redundant auxiliary chain or cable is eliminated to hold the load solely by tensioning the auxiliary chain or cable. The extent of slack is set to insure that slight lengthening of the main chain as caused by wear does not result in loading of the auxiliary chain or cable.

Claim (Index 6):
The hoist security arrangement according to  claim 1  comprising a main chain able to be raised by a hoist drive to lift a load attached to said chain, said security arrangement including a security chain extending along side of said main chain and also moved therewith synchronously by said hoist drive and attached to said load but of a longer length between said load and said hoist drive than said shorter main chain said slack sufficient to prevent tensioning of said redundant chain by the weight of said load so that the load is supported solely by said main chain.
