A hand truck having a frame with first and second ends and a handle adjacent the first end and a platform extending from the second end. Wheels adjacent the second end support the frame and platform for rolling movement. A lever member with first end pivotally connected to the frame at the first end and second free end. A position stabilizing member is pivotally connected to each side of the frame proximate the second end with each shoe assembly being pivotal to a support position extending below a respective wheel. The free end of the lever member is positioned against a surface and the frame pivoted thereabout with the shoe portion of each shoe assembly moving to the support position. An automatic braking system prevents unwanted downward movement. A repositioned lever member and multiple commonly hinged lever members allow for full stair lifting and elimination of the position stabilizing member.
