ABSTRACT:
In this method for washing motor vehicles in a gantry-type washing installation with two movable gantries, washing is performed with a single pair of vertical brushes which wash between two horizontal brushes and are located on one of the two gantries. During a forward movement of the gantries, the washing process is commenced with the first horizontal brush in the front third of the vehicle, while the nose is washed with the two vertical brushes. Then the nose and the top of the vehicle approximately up to the rear third of the vehicle are washed with the second horizontal brush. The direction of travel of the gantries is reversed as soon as the tail wash has been executed with the two vertical brushes and before the second horizontal brush has reached the tail of the vehicle. During the return movement of the two gantries washing with the brushes is continued until the vertical brushes have passed the nose of the vehicle and the first gantry is then stopped while the first horizontal brush is still in the area above the first third of the vehicle. The washing time is thus shortened and the space requirement is reduced.
