This is a new motor-driven transport trolley comprising a frame (1) with a rotating plate (5) on top, having two sets of wheels (2.11,2.12,2.21,2.22), right and left, and two or more hydraulic motors (3.11,3.12,3.21,3.22) which move the two sets of wheels separately to obtain differentiated drive. The motors are hydraulic and are fed by a pressure pump; the motion is differently distributed to the various hydraulic motors by means of valves connected to a control unit which controls the operation of the hydraulic motors, the pressure pump and the valves. This control unit is controlled by a push-button panel connected to it by means of an electric cable, infrared rays or radio waves, etc. <IMAGE> |
