US Patent 10137920 Hand truck assembly

A hand truck assembly for transporting an object includes a frame that is selectively manipulated. A plate is coupled to the frame to support an object thereby facilitating the object to be lifted. A pair of first wheels is each rotatably coupled to the frame. Each of the first wheels rolls along the support surface thereby facilitating the object to be transported. A second wheel is rotatably coupled to the frame and the second wheel selectively supports the frame when one of the first wheels is damaged. A pair of handles is each coupled to the frame for gripping.
