<p>A conveyor arrangement is provided wherein a chain or belt which conveys or serves to drive the conveyor is itself driven by accurately controlled repetitive steps through a rotary drive mechanism powered by a linear actuator. A simple interlock arrangement precludes backward motion. The arrangement is highly reliable, in requiring minimal maintenance or servicing while being suited for accurate operation in hazardous environments such as under heavy irradiation associated with handling of highly radioactive nuclear fuel.</p> |
