Abstract
A hand truck includes a frame, a toe plate connected to the frame, a pair of wheels rotatably secured to the frame, and a handle connected to the frame. A fourth-wheel attachment is pivotally connected to the frame at a first point and removable connected to the frame at a second point. A lever positioned adjacent to the handle causes the removable connection between the fourth-wheel attachment and the frame to be released, allowing the fourth-wheel assembly to pivot away from the frame. An embodiment of a hand truck includes a break back bar. The break back bar is pivotable with respect to the frame. The break back bar may be deployed and stood on by a user to prevent movement of the hand truck while pivoting a load.
