  • Patent number: 4145975
    Abstract: In a load bearing three-way pallet fabricated in a flat substantially square configuration, a transversely disposed open frame forms a central load bearing support which is transversely bridged by an overlying sheet. The sheet is preformed to present a raised load bearing surface having transverse upwardly open channels on opposing sides of the frame for the reception of liftfork fingers and lifting a load off the pallet. Each end portion of the sheet receives liftfork fingers thereunder and spaced-apart transverse slots formed in the channel walls normal to the longitudinal axis of the channels receive liftfork fingers from another direction for lifting the pallet with a load thereon.
