ABSTRACT:
A dual pivot material handler including a base section, a container, a pivot frame, a hydraulic power unit, a hydraulic control unit, and hydraulic cylinders for rotating the container about two pivot points. The container is pivotably mounted to one end of the pivot frame at a container pivot point, and a second end of the pivot frame is pivotably mounted to the base section at a base section pivot point. To rotate the container about the container and base section pivot points, hydraulic cylinders are mounted between the pivot frame and the container and between the base section and the pivot frame. At the initiation of a dump cycle, the cylinders mounted between the pivot frame and the container are actuated to rotate the container about the container pivot point to a horizontal position. In the horizontal position, the container rests on the pivot frame. Next, the cylinders mounted between the pivot frame and the base section are actuated to rotate the pivot frame, with the container resting thereon, about the base section pivot point to a full dump position.
