Portable hydraulic power unit

A hydraulic power unit includes an engine and a pump mounted to a portable frame having an integral fluid reservoir for circulating the hydraulic fluid. Detachably mounted to the frame is a multiple speed winch. The fluid reservoir within the frame comprises the hollow structural tubing of the frame itself. The frame includes a handle for carrying the unit while the winch is in operation and for providing a hydraulic head to the pump and an expansion chamber for the hydraulic fluid. The multiple speed winch includes, in addition to the hydraulic motor, a first rotatable shaft and a second rotatable shaft operatively connected to the motor for providing two speeds to the winch. Each shaft has a freely rotatable hub mounted thereon which is engaged to its shaft by an associated clutch. By engaging and disengaging the clutches, the hydraulic motor may drive either of the shafts directly to reel in the attached cable or play it out.
