ABSTRACT:
A hand truck convertible between forward and sideways displacement has wheels individually disengageable from the hand truck frame for mounting to the frame in either a mutually parallel wheel position or a mutually in-line wheel position transverse to the parallel wheel position. An optional wheel base extension can be installed for in-line mounting of more than two wheels. Other options include a retractable stand for supporting the loaded hand truck in upright position and an auxiliary load carrying shelf. The hand truck and one or more of the optional accessories may be sold as a kit of parts.
