  • Pallet unloading fixture
    Patent number: 4571141
    Abstract: A load vertically stacked on a pallet lowered on a lift fork into a vertically elongated handling zone, enclosed by a guide frame. As the pallet approaches a lower rest position, the load is retained above a support plane on top of rails between which the lift fork tines are vertically movable. The lift fork is withdrawn from the unloaded pallet and reinserted into the handling zone just below the load to raise it through the guide frame during which the load is stabilized on the lift fork.
