ABSTRACT OF THE DISCLOSURE A pallet truck for moving articles is disclosed having a load bearing chassis which can be elevated or Lowered. A hydraulic lifting mechanism is provided for lifting the chassis. The lifting mechanism comprises at least one piston which is fully immersed in the hydraulic fluid employed and a pump with at least one pump piston for actuating the lifting piston. Valve control means are provided in the steering head base which also carries the steering handle. The steering handle is used to actuate the pump piston. The valve control means can be manipulated by the operator for the pallet truck so as to select lowering or raising of the chassis. A neutral position in which the pump is disconnected from the lifting mechanism is also provided. A second valve control means permits the pump circuit to adapt to various loads. The truck in accordance with the present invention is of particularly durable construction and can easily be controlled by the operator.
