Monitoring of conveyor belts in underground mining
Belts in underground mining are potentially hazardous; they must be monitored using simple control points along their entire length. Rope pull switches ensure that the belt can be stopped reliably at any point along the rope in the event of a hazard. In operational status, the rope is under tension and the safety-relevant contacts are monitored by the Flexi Soft safety controller so that potential hazards can be detected. This process can be automated by means of the additional integration of the Flexi Loop safe sensor cascade.
