ABSTRACT:
A hand truck or dolly for transporting longitudinal objects such as plasterboard, doors, panels, mattresses, or the like. The hand truck has a longitudinal base (10) installed at least on a three wheels arranged in line along the longitudinal axis of base 10. At least two of these wheels (94, 96) have axes of rotation fixed with respect to the base, while at least one wheel (98) is a swivel wheel, the axis of which can be turned in a horizontal plane with respect to the base. A vertical frame (27) is formed of stands (14 and 16) and side braces (19 and 21) and is rigidly attached to one side of the frame, while its other side has a short shoulder 12 for protecting an object (102) being transported from sliding and falling from the hand truck. A distinguishing feature of the hand truck is a kickstand (28) which allows one to place the truck in a self-supporting substantially vertical position. In a ground-supporting position, the kickstand is fixed by a a locking arm (34), while in a folded position it is locked to the frame by a U-shaped yoke 54. A tiedown strap (82) can be used for stabilizing the object on the hand truck. The strap has hooks (86 and 87) on its both ends. The strap is wrapped around the object, then one hook is put onto crossbar (22) of the frame, while the other is locked by inserting into one of the holes (88, 90, 92) formed in the shoulder.
