ABSTRACT:
A vehicle wash apparatus includes a reciprocating gantry-type framework with rotating fluid dispensers along an upper extent thereof and at opposite sides thereof which are adapted to be rotated to deliver washing fluid at the vehicle as the apparatus traverses the length of the vehicle. A tilt mechanism is provided so that the rotating manifolds acan be tilted at opposite ends of the vehicle to direct the cleaning fluid at the ends of the vehicle when the apparatus is positioned adjacent the ends of the vehicle. A unique bearing seal element supports the rotating manifolds on a rotatably driven coupling from a motor so that liquid can be delivered to the rotating manifolds in a leak-free environment and over an extended life. An ultra-high molecular weight polyethylene material is utilized in bearing seal members in the element which serve both as a liquid seal and a bearing surface.
