Rollover vehicle washing apparatus with high and low pressure spray systems

摘要

A roll-over high-pressure washer for non-contact washing of stationary vehicles. A gantry frame having two independent U-shaped spray arms is mounted to roll back and forth over the vehicle, while independent low- and high-pressure spray systems mounted on each of the U-shaped spray arms pre-soak, wash and rinse the vehicle in a preprogrammed sequence. The U-shaped spray arms are maintained in close proximity to the upper surfaces of the vehicle, without contacting them, by primary non-vehicle-contacting and secondary vehicle-contacting sensing means. Side spray arms are also mounted on the gantry frame to wash the side surfaces of the vehicle.
