Abstract
A carwash system is disclosed wherein a spray arm dependingly mounted to an overhead longitudinally movable carriage for dispensing fluids onto the exterior surfaces of a vehicle in a wash bay unidirectionally circumnavigates the vehicle for multiple circuits while performing one or more wash functions by coordinating longitudinal and rotational movements of the arm through the selective operation of two independent motor drives. Electrical power and/or data is carried to and from electrical devices on the arm by way of a slip ring conductor which is mounted coaxially with the arm pivot on the bottom side of the carriage. The fluid supply conduit also passes concentrically through this pivot.
