Patent ID: 10882724

Abstract:
A redundant multi-point chain hoist apparatus is disclosed. In at least one embodiment, the apparatus provides a motor, a first chain path sized and configured for slidably receiving a first chain, a separate, redundant second chain path sized and configured for slidably receiving a second chain, a first brake in mechanical communication with the first chain path, a second brake in mechanical communication with the second chain path, and a gear train. The gear train is configured for enabling the motor to selectively cause the first and second chains to move in unison yet independently via the separate first and second chain paths. In use, with the apparatus engaged with each of an elevated surface and a load, the apparatus is capable of selectively lifting, lowering and sustaining the load relative to the elevated surface via each of the first and second chains, even if one of the first or second chains, chain paths, or brakes should experience a failure.
