PURPOSE:To invariably support the carrier of a vehicle body horizontally by stretching a connecting body on large and small belt winding bodies, connecting the centers of both belt winding bodies with a link mechanism, and adjusting the link mechanism. CONSTITUTION:A pair of the right and left link mechanisms 10 supporting a loaded material are fitted on a travel mechanism 1 provided with the right and left crawlers 5. The link mechanism 10 has a small pulley 11 fixed on the side face of the vehicle body of the travel mechanism 1 and a large pulley 12 fixed on the side face of a carrier, an endless belt 13 is suspended around both pulleys 11, 12, and centers of both pulleys 11, 12 are connected by a link 14. The operation of the link mechanism 10 is automatically controlled by the information obtained from an attitude sensor detecting the longitudinal inclination of the mechanism 1, thereby the carrier can be invariably kept hori zontal.
