Abstract
While a portal frame is reciprocated longitudinally of a vehicle body to be washed, a lifting/lowering drum is lifted/lowered to allow an upper nozzle to follow the outer surface of the vehicle body with a predetermined distance and the upper nozzle is laterally moved to inject a washing liquid therefrom, side nozzles are lifted/lowered to inject a washing liquid on the side surfaces of the vehicle body therefrom. In the first going operation of the portal frame, a plurality of photo-sensors disposed vertically which are provided on the front portion of the portal frame detects the vehicle body and information from the photo-sensors is stored in time sequence to perform a comparative operation with the previously set information, thereby controlling the movement of the portal frame, lifting/lowering of the lifting/lowering drum, the lateral movement of the upper nozzle and lifting/lowering of the side nozzles according to each portion of the vehicle body.
