High pressure arch for a vehicle wash system

摘要

A vehicle treatment apparatus for a vehicle cleaning system includes a frame structure having a pair of vertical side supports that are secured to the ground and are spaced apart from one another. The pair of vertical side supports have a generally horizontal treatment member extending therebetween. The horizontal treatment member has a first end and a second end and is configured to communicate with a vehicle that passes thereunder. Each of the pair of vertical side supports include a retention mechanism formed therein for engaging a respective one of the first end and the second end of the generally horizontal treatment member. The generally horizontal treatment member is in communication with a controller to allow substantially vertical movement within each of the retention mechanism from a home position to at least one lower position where it communicates with the vehicle. The generally horizontal treatment member is in communication with a sensor to monitor application of a force thereto. If the force applied to the generally horizontal treatment member is greater than a predetermined minimum acceptable force, the generally horizontal treatment member moves vertically upward to the home position and automatically repositions the end in the event the force applied to the horizontal treatment member is sufficient to dislodge the ends from their retention mechanism.
