ABSTRACT:
A plastic pallet including an upper plastic platform structure defining a load receiving surface and a lower plastic base structure defining the pallet support surface. The platform structure and the base structure are interconnected by leg or strut structures which coact with the platform structure and the base structure to define tunnels for the entry of material handling equipment. A series of upper beams are provided in the platform structure, a corresponding series of lower beams are provided in the base structure, and the struts interconnecting the platform structure and base structure serve to interconnect a respective upper beam with a respective lower beam so as to form of series of trusses within the pallet and optimize the rigidity of the pallet. The leg structures interconnecting the platform structure and the base structure are formed as clusters of small leg portions so as to minimize the size of the openings of the legs in the load receiving surface and in the pallet support surface and thereby preserve the planar integrity of these surfaces.
