ABSTRACT:
A container handling apparatus having a pair of side frames and a cross frame. The apparatus also has four lift mechanisms for attachment to a container. Each lift mechanism is mounted on one end of a secondary lift arm. Four primary lift arms are connected to the side frames and to the midpoint of each of the secondary lift arms. A cam follower on the lower end of each secondary lift arm follows a cam horizontally along one of the side frames. Hydraulic cylinders rotate the primary lift arms about a pivot connection to the side frames. This causes the upper ends of the secondary lift arms to move vertically to raise and lower the lift mechanisms and the container. Transducers connected between the primary arms and the side frames equalize the amount of rotation of each of the primary lift arms and automatically keep the positions of the four lift mechanisms at the same height.
