Abstract
A pivoting door is provided for a carwash vehicle conveyor. The pivoting door does not require counter weights or stops. The pivoting door has a top bar, a pair of arms each with a bottom end and extend from the top bar, and tensioning units. One of the tensioning units is disposed at the bottom end of each of the arms. Each of the tensioning units has a main pin and a spring unit. When a roller pushes the top bar to an open position the tensioning units produce a counter torque for automatically returning the pivoting door to a closed position after the roller passes by.
