  • Skid-steer loader power source attachment and method of manufacture
    Patent number: 6568493
    Abstract: A power source attachment, and a method of manufacture, that runs only off the auxiliary hydraulics of a skid-steer loader or other prime mover. It can run lights and still have extra power to run one or more electrically operated tools on a construction or other jobsite, such as but not limited to welders, jackhammers, air compressors, saws, drills, grinders, and the like. The preferred embodiment comprises a frame, hydraulic hoses, an hydraulic motor, a generator with 110v and 220v plug-ins, and a hydraulic fluid flow control assembly. Optionally, the present invention can be adapted to hydraulically operate devices such as pumps and compressors simultaneously with the electrically powered tools. Since the present invention uses only the hydraulic power and engine horsepower of the prime mover to operate or be moved between locations, it does not require a diesel motor, ignition system, fuel tank, cooling system, or wheels.
