Pull Cord Switch should be installed on both sides of the conveyor where has a maintenance channel, installation position should ensure that the maintenance person operates conveniently in the event of an emergency.
1.Pull Cord Switch is fixed on the rack of rubber belt conveyor.
2.The distance of the two switches on one side is about 50 m, the two switches are connected by the diameter 4mm of wirerope, elastic should be moderate.
3.To reduce the influence of the weight of wire rope on switches, we install supporting ring on the frame every 3 m to support the steel wire rope.

4.The other end of the rope is in tension spring (with rope buckle), in a way not affecting the normal use, using tightener to pull the rope tension on both sides, and to ensure that tension is balanced on both sides.
(Note: The climbing section of the conveyor, should try to shorten the switch spacing distance and the pull rope length.)
