  • Patent number: 4114941
    Abstract: A crate grappling device having a generally U-shaped frame including a pair of coplanar arms and a cross member connected to the arms at one end. A pair of hook-like members are secured to the free ends of the arms, which are adapted to engage the wooden frame structure of a palletized crate so that with the aid of a winch or some other pulling device the crate may be dragged along the bed of a truck or trailer to the tailgate. Formed as an integral part of the hook-like members are skids which bear the wear of the grappling device as it is dragged along the bed.
