Abstract
A combination hand truck, dolly and step ladder device includes a hand truck frame and a step ladder frame that are pivotally attached to one another and can be fixed at selective angles with respect to each other to form a hand truck, a dolly and a step ladder. In a step ladder configuration, the top step of a step assembly is secured to a cross member of the hand truck frame so as to lock the hand truck frame and the step ladder frame into a substantially fixed relationship to one another. In a dolly configuration, the hand truck frame becomes the handle for the dolly, and is held in place by a support bar that pivotally attaches to the hand truck frame and secures to the step ladder frame.
