  • Patent number: 5232329
    Abstract: A cargo handling apparatus is described for lifting, transporting and unloading cargo in connection with a vehicle, such as a pickup truck. The apparatus is fastened to the vehicle and has a separate platform upon which cargo is placed and attached while the platform is on the ground. An end of the platform then is raised by a winch and cable to a height approximately to the bottom of a boom assembly. The boom then is lowered slightly to a slope approximating the slope of the platform and attached cargo. The platform now is movable along the boom by the winch and cable, and finally, the boom is pivotable down onto the vehicle. All operations are controlled from a hand held unit.
