VEHICLE WASH SYSTEM

An open top wash system having separate wash mechanisms on opposite sides of a wash zone provides considerable flexibility and efficiency by allowing vehicles of several heights to be washed. The wash mechanisms are further configured to provide additional efficiency by allowing wash and/or rinse nozzles to be positioned in close proximity to the vehicle, thereby limiting amount of water need for washing operations. The wash system also has several sensors positioned and controlled to trace a vehicle in the wash zone, thus providing significant information for use in positioning both side wash spray nozzles and tracer wand spray nozzles during wash and rinse operations. Although the control system is capable of careful control of nozzles, mechanical breakaway systems are further included should physical contact with the vehicle occur, thus allowing an additional level of safety.
