ABSTRACT:
A dolly for pushing a vehicle through a car wash and including an inclined arm having a leading end located below a track of the car wash and attached to a continuous conveyor chain. A track engaging pair of rollers is carried below the track by the leading end of the arm while a trailing pair of rollers is supported by the track. An elevated pair of rollers engage an auto wheel for pushing of the auto while simultaneously contacting the track supported trailing pair of rollers. Loads imparted to the tire engaging rollers are accordingly transferred to the track with a reduction in loads imparted to roller axles. A floating mounting arrangement for the tire engaging rollers maintains roller engagement regardless of roller wear.
