REPOSITIONABLE HAND TRUCK ABSTRACT OF THE DISCLOSURE A two-wheeled hand truck incorporates an elongate upright frame, mounted by a pair of wheel support brackets to supporting wheels. Handles or other graspable surfaces are provided at the upper end of the frame. The wheel- supporting brackets are pivotally connected to the frame in a manner to permit movement of the wheels from a first load-supporting position in which the wheels are adjacent the lower end of the frame for supporting loads with a relatively lower center of gravity, to a second load-supporting position in which the wheels and axle are moved materially rearward for supporting loads with a relatively higher center of gravity. Yieldable, pressure-exerting means operating through moment arms on opposite sides of the bracket pivots releasably lock the wheel structure in each of its positions.
