A hydraulic power take off device for an endless conveyor belt system or the like having an upper material run (1) and a lower return run (2), said device being arranged to generate hydraulic fluid at pressure to maintain a self adjusting force to belt cleaning equipment, and other equipment that can utilise fluid pressure. Said device is driven directly or indirectly from the motion of the conveyor belt or from the motion of other components fitted to the endless system. The power take off comprises a hydraulic pump (23) which is rotated by the motion of the endless conveyor and generates fluid at pressure via an adjustable relief valve and maintains a constant self adjusting force to actuators (62), automatically compensating for wear that takes place on the equipment being operated and providing an automatic and interlocked source of power, generating pressure only when the conveyor belt system operates.
