| 摘要 |
The present invention provides an improved exterior rollover vehicle washing machine and/or cleaning system including an external frame, a gantry having no internal propulsion, a motor, a drive line/pulley system, at least two washer arm assemblies, a water supply line and a chemical supply line. In one embodiment, the motor has belt and pulley members to move the gantry back and forth along a frame track. The washer arms can move horizontally alongside the vehicle from vehicle front to vehicle back, as well as horizontally toward and away from the vehicle. The washer arms can further be pivotally mounted to the gantry so as to move within a 90 degree range such that the water supply line and/or chemical supply line can rotate from approximately 45 degrees to one side of the normal line directed at the vehicle to 45 degrees on the other side of the normal line directed at the vehicle.
