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 9):
A method of preventing dropping of a load held by a main load carrying wrappable lift element in a hoist upon breakage of said main lift element, comprising installing a security wrappable load element alongside said main lift carrying load element of a sufficiently longer length than said main load element so as to avoid tensioning said security load element, said load connected to both said main and security load elements, wherein the wrappable main lift element and the security wrappable load elements are at least partially wrapped around a drive member, said main lift element shorter than said redundant lift element so that slack is created in said security lift element whereby if said main lift element breaks said security lift element thereafter immediately begins to support said load.
