ABSTRACT:
An applicator is supported by primary and secondary arms for movement along the contour of the front, top and rear surfaces of a vehicle. The applicator is shifted to a position out of the path of vehicle travel in the event of electrical power or pressure fluid failure. A sensory mechanism controls actuators which position the primary and secondary arms. From a lower rest position, the primary arm is raised to progressively position the applicator above the hood and roof areas of the vehicle. The primary arm is then dropped to its rest position while the secondary arm is raised and knuckled toward the primary arm to maintain the applicator above the vehicle roof. The secondary arm is extended as the vehicle passes.
