ABSTRACT:
A vehicle washing apparatus includes a side track extending along a washing bay. A gantry is supported for reciprocal motion along the side track by a gantry motor. Sensors detect the front and rear ends of the vehicle to control movement of the gantry. A retractable carriage extends from the gantry across the washing bay under the control of a carriage motor and a vehicle width sensor. The carriage rotatably supports a spray bar for discharging cleaning fluid. A motor rotates the spray bar to sweep around corners of the vehicle. A cam plate and engagement roller index the spray bar orientation, while limiting spray bar rotation to a single direction. A wheel guide receives the front left vehicle wheel. Treadle switches in the wheel guide, in conjunction with an illuminated display, indicate to the user when the vehicle is properly indexed in the washing bay.
