ABSTRACT:
A differential hoist and drive includes a differential escapement mechanism arranged mechanically between and in combination with a pair of direction turning members, such as pulleys. An endless loop of a flexible force transmitting element (cable, chain, strap, or the like) interconnects the direction turning members and the differential escapement. The load can be connected to either the differential escapement or the direction turning members with the other being anchored as a fixed member. The load is restrained from swinging or from other unintended movement. A turnbuckle or other suitable device provides for a desired pretensioning of the loop of flexible force transmitting element.
