Abstract
An improvement to cable conveyor system using a pneumatic cylinder system for keeping a cable tight is provided for preventing damage to the system if the cable stretches/fails or is too loose. The fluid cylinder/piston applies a force on the cable proportionate to the pressure that is regulated to the cylinder during normal operation of the cable conveyor system. The relative position of a magnetic switch and a magnet on a piston in the cylinder, provides a way to sense a lack of tension in the cable and shut the system down before damage is done to the conveyor. Likewise, if the cable stretches or fails, a carriage having an idler thereon, will move close enough to a proximity switch to cause the proximity switch to shut down the system.
