  • Patent number: 8944239
    Abstract: A conveyor apparatus includes a frame, and a pivoting conveyor coupled to the frame. The pivoting conveyor includes a pivotable conveyor section having a free end shaped for supporting objects and a first conveying surface. The first pivotable conveyor section is pivotally coupled to the frame about a vertical axis for pivoting the free end from side-to-side, and a horizontal axis for pivoting the free end up and down. The pivoting conveyor also includes a second non-pivotable conveyor section having a second conveying surface. Furthermore, the pivoting conveyor includes a fixed transition plate located adjacent to the second conveying surface, and a shuttling transition plate located adjacent to the first conveying surface. The shuttling transition plate is configured to move laterally from side-to-side relative to the first conveying surface as the first pivotable conveyor section pivots about the vertical axis.

  • Patent number: 8464859
    Abstract: A conveyor apparatus comprising a frame removably connectable to an extendable conveyor and a pivoting conveyor coupled to the frame. The pivoting conveyor includes a slewing conveyor section pivotally coupled to the frame for pivotal movement about a generally vertical axis, and a tiltable conveyor section having one end pivotally coupled to the slewing conveyor section for pivotal movement about a generally horizontal axis and an opposing free end shaped for receiving objects being unloaded from the shipping container. Each section includes a conveying surface for conveying the objects from the free end of the tiltable conveyor section, and toward the extendable conveyor. The free end of the tiltable conveyor section can be moved from side-to-side by pivoting the slewing conveyor section about the vertical axis, and can be moved up and down by pivoting the tiltable conveyor section about the horizontal axis independent of the slewing conveyor section.
