ABSTRACT:
An above the floor conveyor is provided for transporting a wheeled vehicle having a plurality of tires across a floor surface with a pair of the vehicle's tires oriented in a guided track. The conveyor includes a drive and idle sprocket which are spaced apart and have an endless tensile member extending in a loop thereabout to define a drive and a return flight. A series of dolly assemblies are attached to the endless conveyor tensile member in spaced apart orientation. The dolly assemblies have an elongated dolly roller for engaging a tire of a vehicle located within the guided track. The dollies are pivotable about a generally vertical dolly axis between an inactive position in which the dolly roller is pivoted rearwardly out of the guided tracks and an active position in which a dolly roller extends inwardly into the guided track. The dolly assembly has an arm extending outwardly from the pivot axis providing a follower spaced from the axis. A dolly guide rail is fixed parallel to the drive flight for cooperating with the dolly follower to support the dolly when in the active position. An actuator is provided to selectively shift the dolly between the inactive and active positions on demand.
