A vehicle-washing installation
Реферат: Two rotary scrubbing brushes, suspended from the lintel of a portal frame which straddles the path of a vehicle to be washed, are so balanced as to hang at an angle from the upper corners of the frame with their lower ends touching or crossing in the region of the centerline of the path. According to its direction of rotation, a brush coming into contact with an end of a vehicle moving relatively to the portal frame is swung either outwardly, to scrub a side of the vehicle, or upwardly to sweep a horizontal top surface thereof.
