Car wash conveyor
ActiveUS7243605B1Permit useProvide stabilityConveyorsCleaning apparatus with conveyorsEngineeringLaundry
An auto-laundry conveyor of three-tier design using upper, lower and intermediate track rails with a narrow slot between them. Dollies are provided in an endless loop conveyor chain and each dolly comprises a combination of a center link, a pair of reversely similar tire engaging rollers, a pair of reversely similar track engaging rollers outboard of the tire engaging rollers and a pair of reversely similar stabilizing rollers outboard of the track engaging rollers. The stabilizing rollers are effectively larger in diameter; i.e., higher than the track engaging rollers so as to prevent rolling contact between the stabilizing rollers and the track surface and to receive the tread surface of an off-center tire and keep the tread surface from interfering with rolling movement of the track engaging rollers. The conveyor is manufactured in 10-foot lengths except for the entry and exit sections which are of lengths X and Y wherein X plus Y equals 10 feet. An open track structure is used to prevent the accumulation of dirt and debris.
