Abstract
A drive apparatus for a cable conveyor system having a channel formed adjacent to a drive wheel for receiving a partial loop of excess cable for the purpose of preventing the cable from becoming too tight or too loose for the proper functioning of the system. A switch assembly is positioned adjacent to one end of the channel for sensing an enlarged partial loop of cable and shutting off the power to the drive apparatus in response to such condition.
