A vehicle is proposed, in particular a chassis of a bridge-underside inspection apparatus, having a frame (1) and road-vehicle wheels. In order to be able to quickly and simply convert such a vehicle into an operational chassis having increased stability, a pneumatically sprung axle unit (3) and, in front of and/or behind this pneumatically sprung axle unit, at least one unsprung auxiliary wheel (7, 8) are arranged on the frame (1). The axle unit (3) has a pneumatically actuated device (4, 5) which is connected to the spring- suspension arrangement and by means of which the frame (1) can be lowered from a top position in which the spring suspension is effective into a bottom position. The auxiliary wheel (7, 8) is lifted from the roadway in the top position of the frame (1) during the road- transport operation and stands on the roadway in the bottom position of the frame (1) during working operation. Supporting rollers (6), which also serve as a slow drive, can be arranged above the wheels of the axle unit (3) (Fig. 1).
