ABSTRACT:
A hand truck has a pair of horizontally spaced, vertically extending side rails connected laterally to form a hand truck frame which has a handle incorporated with the upper portion thereof. Unique axle supporting brackets fixed to the inner sides of the lower end of each side rail extend rearwardly to an axle and wheel mechanism for supporting the frame which has a nose plate. A brake disc rim is secured to each wheel and a brake actuator is mounted on the frame near the hand truck handle to operate normally slacked flexible cables which are trained around the discs and guided by a bracket secured mechanism.
