Abstract
The present invention is directed to a carrier and conveyor system that permits the carrier to be driven by at least two different types of conveyors or drive assemblies, including a power and free conveyor. The system includes a plurality of carriers, first and second areas, a power and free conveyor assembly, and a friction drive assembly. The power and free conveyor drivably engages the first and second carriers when the carriers are in the first area and is out of driving engagement with the carriers in the second area. The friction drive assembly is engageable with each carrier when the carriers are in the second area and out of driving engagement with each carrier when the carriers are in the first area.
