  • Patent number: 4806063
    Abstract: A portable wild game hoist having a multiple section boom which can be assembled and dismantled. The boom is supported at its lower end by a standard trailer hitch mounted on the rear of a vehicle. Straps are secured to the upper section of the boom and terminate in hooks at their distal ends which are adapted to mate with the edges of the fenders of the vehicle. A torsion bar is adjustably secured to one section of the boom so that is bears against the rear body or tailgate of the vehicle. A rope extends from a winch secured to the boom through a pulley at the distal end of the boom. The rope supports a hanger with hooks for supporting the animal from its rear hooves. In a further embodiment, the boom may be supported by a base resting on the ground and stabilized by the trailer hitch. In both embodiments, the boom is comprised of a plurality of mating sections.
