PURPOSE:To reduce the manhour for the transport work and prevent the generation of electric noise by installing a driving means for extending and contracting the driving part of a jack and installing a balance adjusting member for adjusting the truck balance in case of loading at a prescribed place on a truck frame, in demountable manner. CONSTITUTION:Driving wheels 26 are revolved by the driving power of an air motor, and a transport dolly 10 is travelled toward an aimed place. Accordingly, the transport dolly 10 can travel without generating the electric noise. At this time, a following mechanism having a spring damper 30 is installed on the driving wheel 26. Accordingly, when the transport dolly 10 travels on an uneven floor surface 56, the force which is applied from the uneven floor surface 56 and springs up the driving wheel 26 can be absorbed by the spring damper 30 of the following mechanism, and the driving wheels 26 are revolved, always following the uneven floor surface 56.
