ABSTRACT:
A transport system is provided which includes a conveyor having an alternate forwardly and reversely driven rollers. A carrier disposed on the conveyor has a pair of spaced skis which engage the forwardly rotating rollers to move the carrier along the conveyor. A friction belt disposed over a pair of pickup rollers on the carrier engages the reversely rotating rollers on the conveyor to provide a rotational drive for use on the carrier. An alternative embodiment is also disclosed which provides rotational motion on the carrier only when the carrier is moving along the conveyor.
