  • Publication number: 20020150452
    Abstract: An apparatus for unloading packages, parcels, postal items, baggage, etc., from a container having an open side. The apparatus has a sliding wall that is disposed over the open side of the container when the container is receiving within the apparatus. The apparatus, along with the container, is tilted such that the open side of the container is generally directed downward. From this tilted orientation, the sliding wall of the apparatus is withdrawn, incrementally exposing the open side of the container, permitting the controlled egress of the packages, etc., from the container.

  • Patent number: 5865590
    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.
