The switches are connected by a safety cable that runs between the switch arms and can either be attached to the outer hole 6,80 Kg pull force or the second inner hole 11,34 Kg pull force.
The cables are secured by cable clamps after they are looped through the switch hole. The ends of the cable can either be a switch or a conveyor eye bolt secured with a clamp.
To prevent the pull cable from sagging, conveyor standoffs (eye bolts) are mounted every 3 meters. The distance between switches is dependent on the variations in temperature of the environment.
Normal spacing based on a temperature of 60°C is a maximum distance of 45 Meters on inclined conveyors and 60 Meters on horizontal conveyors.
It can be up to 90 Meters in indoor environments and it should be 30 meters in extreme environments.
