  • Patent number: 6202868
    Abstract: A vertical lift hoist and winch is taught which can be used, for example, for suspending wild game animals for the purpose of field dressing. The assembly is collapsible without any disassembly of major parts, to be able to fold up into a convenient carrying position, or to be capable of storage in a normal automobile truck, Jeep or station wagon compartment or a truck tool box. The winch lift assembly permits convenient storage and ease of set-up, where all pieces are held together as one. The pulley's are recessed in the upper boom which allows a tight closure in the collapsed position which is an advantage over other types of lifts. Nothing hangs down below the boom, thereby eliminating any cable tangles or interference when setting up or storing.
