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 5):
The hoist security arrangement according to  claim 2  wherein a lower end of each of said link chains are both attached to a chain nest and said chain nest is mounted to be rotatable relative said load whereby any tendency for twisting together of said link chains by rotation of said load is minimized.
