ABSTRACT:
A compact, light weight, back packable winch and power source, including a cable quick release device to facilitate single handed use of the winch. The power train and cable retrieval mechanisms are mounted on one side of a back pack frame or platform, and straps and padding enabling the mechanism to be carried like a back pack are mounted on the other side of the frame together with folding legs that assist in supporting the assembly during operation. A substantial quantity of small diameter cable is wound onto the winch spool by a level wind mechanism. The spool and level wind mechanism are powered, through chain and sprocket assemblies, by a hydraulic motor. The hydraulic motor is powered by a compact gasoline engine that operates a hydraulic pump to supply hydraulic fluid to the hydraulic motor, controlled by a flow control valve. The quick release utilizes pincers attached to the cable end and a shroud that holds the pincers closed around a chain link or loop and that may be slipped out of engagement with the pincers to permit them to open and release the load attached to the chain link or loop.
