ABSTRACT OF THE DISCLOSURE A hand truck for transporting loads which obviates the necessity of tilting the load prior to positioning the latter on the hand truck. The hand truck is devoid of any bottom plate and carries a pair of jaws clampable on the top flange, or bead, of a load and which suspends the load along the inclined truck frame when the truck frame is moved about on its wheels. The hand truck is further characterized by the provision of a foot-operated jack mechanism to raise the clamped load along the truck frame, 80 that the load may be deposited at any desired elevation when its destination is reached. The jaws are so arranged that they automatically increase the clamping pressure clamp on the load bead, or top flange, when the load exerts a downward pull on said Jaws. The hand truck has, in addition to the usual pair of wheels, a pair of feet on which the hand truck is supported when in upright position with the wheels off the ground, ready to grab the load; these feet come off the ground when the wheels come in contact with the same to move the load about. The jacking mechanism can raise the load to such a position that its center of gravity will fall between the feet and wheels, so that the hand truck, with its load, can be left unattended, since it is stable with both feet and wheels supported on the ground.
