  • Publication number: 20130270785
    Abstract: A hand truck comprised of a frame assembly and a wheel assembly connected by slidable cylinders permitting both vertical and rotational movement between the cylinders. The frame assembly cylinder is mounted at a predetermined angle so that when the cylinder is vertical, the frame is reclined in a load balanced attitude. While in the load balanced attitude, the frame assembly can be raised by any suitable means in relation to the wheel assembly on a surface. Once the frame assembly is at a height great enough to clear the wheels, the wheel assembly can be rotated thus enabling movement parallel to a linier load. Further, when the frame assembly is in the lower position, the two slidable cylinders are locked together to provide use as a conventional hand truck or unlocked and reoriented, thus providing the ability to move a linier load laterally with ample ground clearance.
