Abstract: A portable pallet assembly which is made up of two or more lightweight, moldable plastic modules of high structural integrity which are interconnected by novel interconnection mechanisms. The modules can be connected in a side-by-side relationship to form a rigid pallet assemblage having a substantial surface area. Alternatively, first and second modules can be connected in a side-by-side configuration to form a first assemblage to which a second assemblage made up of third and fourth interconnected modules can be connected to form a rigid, double layer pallet construction. Additionally, individual booster units can be connected to raise the assemblages sufficiently to permit the forks of a forklift truck to be received beneath the article supporting surface of the assemblage.
