Abstract: An improved power assisted hand truck includes a lower frame and an upper, upwardly extending, tilting frame for supporting a load in generally upright and rearwardly tilting orientations. The upper frame is tilted forward by a first hydraulic actuator mounted between the lower and upper frame portions. To stabilize the hand truck while raising the load, a stabilizer, pivotally mounted to the frame, is driven by a second hydraulic actuator mounted between the frame and the stabilizer.
