Safety Rope Switches

Large hazard zones, for which safety doors cannot be used, have to be secured. Another effective option is to use fencing ropes with safety rope switches.

Examples are extended manufacturing islands or conveyor belts. The rope is fixed to both the ends of the safety rope switches. In a hazard situation, the plant can be immediately locked and safely switched off by tugging at the tight rope. Even when there is a tear in the rope, the switches ensure immediate machine standstill. This condition remains locked till the reset pushbutton is pressed when the rope is under correct tension.

Different variants are available for different rope lengths. An additional emergency stop key can be mounted on both sides of the switches.

With the ZANDER assembly / rope tensioning system ZTK, the pre-tension of the rope can be easily set so that green arrows are visible in the display window of the safety rope switch. This simplifies the assembly, troubleshooting and maintenance procedures.

Significant advantage of the ZANDER safety rope switches are the integrated monitoring options. A viewing panel shows the correct rope tension. If required this can be quickly and easily adjusted with our tensioning system. A big LED on the switches indicates the current operating status, which is visible from a large distance. If the LED is green, everything is OK; a red blinking light indicates that the machine has been stopped.

For the food and chemical industry, we offer our switches and accessories even in stainless steel design.
