Abstract: A load advancement mechanism characterized by a slip coupling driven by a constant speed gearmotor coacting with an initial torque imposed by a constant tension spring to advance a load engaging arm at a constant speed to a stop and further adapted to be retracted manually by pulling back on the arm.
