  • Patent number: 6042329
    Abstract: A pallet jack attachment to be coupled to the forks of a conventional pallet jack so as to be able to engage and drag a standard pallet on which goods are stacked out of a shipping container when the pallet is loaded sideways therewithin. The pallet jack attachment includes a pair of arms projecting rearwardly in spaced, parallel alignment with one another. Locking tabs are welded to the rear ends of the arms and sized to fit within and slide through existing slots formed in the forks of the pallet jack so that the pallet jack attachment is reliably connected to the pallet jack. A channel having a pair of gripping fingers turning upwardly therefrom is located at the front of the pallet jack attachment. When the pallet jack is driven towards the side of a pallet, the channel and gripping fingers of the attachment are correspondingly advanced inwardly thereof via an access opening in the pallet.
