发明名称 Four-wheel hand truck with elevator
摘要 An elevator handtruck having four wheels for allowing loads to be moved like an elevator and raised and lowered out from the raised rear edges of a truck such as a pickup truck, moving van, and the like. Safety straps can attach the handtruck to flanges mounted on the wheel wells within a flat bed of the truck vehicle. A motorized carriage having a set of wheels can be slidably mounted on shafts on the rear of a two wheeled handtruck. The carriage wheels can be folded downward when not in use. During use, the carriage wheels sit on the edge of the truck bed such as the tailgate. A user holding a hand control can press buttons causing the carriage to slide up and down causing the entire handtruck to raise upward to the flat bed or downward to the ground. Power can be supplied by attaching jumper cable clip ends connected to the carriage motor on the handtruck to the terminals on the standard vehicle battery.
