Abstract

A crane hoise drive assembly having a hydraulic motor (20) driven by a variable displacement hydraulic pump (21) and a control circuit (10) for the pump adapted to govern the pump displacement so that the lift generated by said motor is independent of line travel and is adjustably predetermined.
