Belt conveyor safety cable pull switches are designed for providing a switching system to isolate the power to conveyor system and other equivalent process equipment in the emergency condition in the event of torsional belt movement due to uneven side loading. The cable pull switches are actuated by a plastic coated steel wire, which are placed along-side the conveyor. When you pull on the cable at any point, it will trip and automatically lock the switches, de-energizing the conveyor starter contactor. Each switch is bi-directional in operation and has two cable fitted to it from opposite directions terminated with a spring at the anchor points, will operate the switch on cable breakage. After tripping, the mechanical latch can be released only on the switch itself by the reset lever. Applications include emergency or normal stop for: conventional belt conveyors; shuttle conveyors; bucket elevators; packaging lines; stockpile/reclaim systems, cranes, shovels; draglines; ship loading/unloading system; horizontal feed systems.
