Guardian Line Heavy Duty Safety Rope Pull Switches with Dual Head (GLHD)
The GLHD heavy duty safety rope pull switch, or grab wire switch, has been designed to protect long conveyor lengths. The dual head is capable of protecting up to 250m and shorter rope spans up to 200m can be achieved using a single switch. This makes for a cost-effective solution, as it reduces electrical wiring runs and the total number of switches required.
