ABSTRACT:
A plastic pallet in which a base structure is positioned beneath the plastic main body of the pallet to discourage warpage and failure of the pallet especially in racked, loaded storage situations. The plastic structure of the pallet includes a planar platform section defining an upwardly facing load receiving surface and a plurality of legs extending downwardly from the platform section to define tunnels therebetween for receipt of the forks of a forklift truck. The base structure includes a lower plastic sheet, an upper plastic sheet, and a plurality of tubular metallic beams positioned in hollows defined between the upper and lower plastic sheets. The hollows in which the beams are received between the sheets are defined within ribs formed on the upper face of a lower planar portion of the base structure and the ribs are respectively secured to respective rows of legs of the main body structure by locally heating the upper faces of the ribs and locally heating the bottoms of the legs of the main body structure to a fusible condition and thereafter pressing the main body structure and the base structure together to fuse the structures together at the interface between the ribs of the base structure and the bottoms of the legs of the main body structure.
