ABSTRACT:
A rotating head frame and load ejector assembly having a pair of opposing and parallel rotating side arms which can rotate between a loading and dumping position is disclosed. The bottom ends of the side arms are pivotally attached to the side walls of the dump body so that the arms can rotate about a side pivot pin to form an arcuate path between the loading and dumping position. A transverse bar attached to the top end of the arms carries a load ejector so that when the arms are rotated to the dumping position, the load ejector dislodges the load from the bottom of the dump body. In order to prevent the head frame from damaging the dump body during its rotation along the arcuate path, means for controlling the rate of rotation of the head frame is provided. A hydraulic cylinder is pivotally attached to each rotating arm and the side wall of the dump body. As the piston rod of the hydraulic cylinder slides within the piston chamber in response to the rotation of the side arms, internal chambers are formed. The internal chambers are in communication with a pressure assembly which ensures that the internal chambers are filled with hydraulic fluid. The presence of the hydraulic fluid in both internal chambers controls the rate of movement of the piston rod in both directions. Thus, the rate of movement of the piston rod and, concomitantly, the rate of rotation of the rotating arms is always controlled as the rotating arms rotate between the loading and dumping position.
