Abstract: This invention provides a refuse packing apparatus including a frame defining a track along which a ram is adapted to reciprocate. A hydraulic cylinder urges the ram in either direction, and the rearward end of the hydraulic cylinder is connected to a lever member which in turn is spring-biased to an "at-rest" position. Under overload conditions, additional force is exerted by the hydraulic cylinder against the lever, and the latter is caused to pivot against the restoring tendency of the spring biasing means. Pivoting movement of the lever which exceeds a predetermined amount is caused to trigger a sensing component which is capable of reversing the direction of the ram by reversing the hydraulic cylinder.
