Abstract
Abstract This invention relates to an integral one piece pallet made of plastic and including a platform section with three support legs depending therefrom and extending from one side of the pallet to the other. Strengthening ribs, which are generally W shaped in cross-section, are disposed adjacent the side of the pallet and extend between the support legs with the bottoms of the ribs being substantially coplanar with the bottoms of the support legs. These W-shaped strengthening ribs have openings therethrough through which a lift device may be inserted. Reinforcing ribs extend between the support legs and their lower extremities are disposed above the openings in the strengthening ribs so as not to be engaged by the lift means inserted through the openings in the strengthening ribs.
