Abstract: A compacting system including a double action vertical ram pivotally mounted within a container. The container includes a front wall, a rear wall, a pair of side walls, a floor and a lid. An opening in the front wall allows refuse or other material to be deposited into the container. A hingedly mounted door covers the opening. The ram includes a pivotally mounted compression plate and a cylinder mounted to one of the side walls with one end thereof mounted above said plate. A shaft extends from a housing of the cylinder and is attached within the container to the plate. In a compaction cycle, the compression plate can travel from a "vertical" position to a substantially "horizontal" position, and compacts the refuse between a lower surface of the compression plate and the floor. A power unit located outside the container provides power to actuate the cylinder. A magnetic safety switch and a door interlock device provide safety features for the compacting system.

Abstract: A handling mechanism for roll-off containers includes an elongated lift frame pivotally connected to a truck chassis, hydraulic tilt rams connected between the lift frame and the chassis, a slide member mounted in tracks along the lift frame, a stationary pulley mounted on the lift frame for rotation in a vertical plane, a movable pulley mounted on the slide member for rotation in a vertical plane, and a pair of container lift rams mounted along the lift frame and connected to the slide member. A cable is connected to the side member, is reeved about the stationary pulley and the movable pulley, and extends to the rear for connection to a container. The lift frame is tilted up and back for loading and off-loading the container. For transportation, the lift frame is tilted to horizontal.
