  • Patent number: 6089431
    Abstract: A hoist for lifting game animals or other loads comprises a boom mounted on a support column in communication with a base. The boom is rotatable relative to the base, which is insertable within a draw bar-type hitch receiver. The boom, support column and base are modular components that advantageously allow for quick assembly/disassembly of the hoist and compact storage of the hoist components. Further, the length of the hoist is adjustable to compensate for the size of the game animal or load being lifted. Additionally, a light source is attached to the hoist to illuminate the area near the hoist to increase safety during operation of the hoist. Finally, a dual draw bar for increasing the utilization of a draw bar-type hitch is included. The dual draw bar has at one end a draw bar adapter and at the opposite end a first and a second receiver section for utilization with draw bar-type accessories.
