A follow-up control device comprising a pneumatic cylinder connected in series or parallel with a hydraulic cylinder for controlling the movement of a load device relative to a further device, such as for transferring an article or commodity from a load device onto the hanger of a movable conveyor. The pneumatic cylinder functions as the power source for moving the load device, and the hydraulic cylinder functions as a speed control for controlling the speed of movement of the load device. The hydraulic cylinder is coupled with a substantially closed hydraulic circuit for controlling the movement of the load.
