  • Patent number: 4362458
    Abstract: Apparatus for moving large, heavy, unwieldy objects includes a pair of hand trucks, each of which has a frame with a lift plate slidably mounted in the frame. A jack is positioned on each frame to raise and lower the lift plate. Two pairs of wheels are mounted on the base of each frame with one pair of swivel wheels mounted on the underside of the base and a pair of fixed wheels of larger diameter than the swivel wheels being secured to the base. The perimeters of the fixed wheels are above those of the swivel wheels by a slight distance when the hand trucks are substantially vertical. Large, heavy objects such as refrigerators, vending machines, and the like, are positioned between the trucks and are supported on the lift plates by being positioned on the lift platforms with which each lift plate is provided or by being supported by attachment brackets to the lift plates. The weight of the object is transferred to the wheels of the trucks by operating the jacks to raise the lift plates.
