ABSTRACT:
A pallet for the handling and transportation of material which is molded of plastic. The pallet is fabricated from a top and base, these two generally similar molded half sections being joined together to form an integral unit. Each such section has a border frame with diagonal stringers running between portions of the frame, there being two sets of stringers, the stringers of one set being orthogonal to those of the other, to form a structural lattice. There are a greater number of stringers (typically twice as many) in one set of stringers than the other. The set of stringers having the greater number of stringer elements on the top section runs parallel to the set of stringers having the lesser number of stringer elements on the base section, and vice-versa, to afford higher structural integrity to the assembled unit. Post or leg members extend inwardly from each section and are joined together at the interface between opposing such leg members to form structural trusses between the structural lattices.
Four apertures are provided in the base section to receive the rollers of the tines of a handjack with entry from any of the four sides; these apertures being formed by ringed portions equally spaced between the legs of each quadrant of the base half section. Such base ringed portions have interlocking base tabs formed thereon which mate with corresponding top tab recesses on similar ringed portions formed in the top lattice section which does not have apertures, thereby facilitating the stacking of the unloaded pallets.
