ABSTRACT:
A reduced weight fifth wheel generally mountable on a tractor for coupling between a tractor and a trailer, which fifth wheel has the approximately the same bearing surface area, a more continuous surface area by elimination of a lever-bar pin port in the bearing surface, thinner support ribs and smaller fillets, a shorter longitudinal length with a wider kingpin receiving slot for receipt of a trailer kingpin, with a locking-jaw mechanism having a redesigned lever-bar pin and pin-receiving port to enable reduction of the weight and to enhance production casting practices.
