Abstract

Under the action of relative motion between a hoisting machine support and a load, a movable component such as a pulley-block carried by the hoisting machine is capable of free displacement under gravity between two end positions of abutment when that end of the movable component which is intended to cooperate with the load is stationary with respect to the load, thereby compensating for any variation in distance between the load and that portion of the hoisting machine which carries the movable component. The equipment unit is designed primarily for hoisting operations performed at sea or on wharves.
