Conveyor belt monitoring systems
The pull-rope switches, belt misalignment switches, limit switches and belt damage detectors in our KBT-Europe product line have a particularly robust design and guarantee a long service life in harsh industrial environments and in mining.
Pull rope switch | pull rope emergency stop switch
Pull-rope switches (pull-rope emergency stop switches) are connected to a pull rope that runs along the accessible sides of the conveyor. A person can switch off the conveyor in the event of danger by briefly and forcefully pulling (tearing) on the pull rope. The ripcord switch engages in the triggered position and must be manually unlocked again when the hazardous situation is over.
