Abstract: A wooden upper deck is connected by two types of plastic spacer blocks to a wooden lower deck. The upper deck may be a conventional deck composed of stringers and slats or it may be a twin sheet thermoformed plastic deck. The lower deck is composed of stringers which underlie the plastic spacers and tie boards which abut the ends of the stringers. Connector spacer blocks serve both to join the upper deck to the lower deck and to connect the stringer boards to the tie boards. The stringers and tie boards are held in fixed relation by bolts which join the upper and lower decks passing through sockets in the spacer blocks. The stringers and the tie boards are bolted to the spacer blocks and are thus joined. The joint between the stringers and the tie boards may be strengthened by means of a metal link overlying the stringers and tie boards and linking the bolts together.

Abstract: A twin sheet thermoformed pallet upper deck has a reinforcing metal substrate and downwardly protruding detents which engage with a hoisting cable or strap. Notches are formed on the sides of the top deck and restrict the escape of the cable when the pallet is elevated. A twin sheet thermoformed, metal substrate reinforced, lower deck is bolted to the upper deck through injection molded plastic legs which have upper and lower protrusions which fit within semi-circular pockets located on the upper and lower decks. Fasteners extend through metal gusset plates welded to the upper and lower deck substrates to form a rigid and strong pallet.
