Belt Conveyor Protection
Wire-rope type Emergency Stop Switch
Just One Unit Covers a Wide Range of Emergency Actions Ideal Replacement for a Multitude of Emergency-Stop Pushbuttons
The PULLSTOP is a switch that is used to stop a conveyor line or similar long-distance transport line by puling on the conveyor s wire rope. The switch also stops the transport line when the wire rope becomes slack or breaks. With an emergency stop pushbutton equipped on the main unit as a standard feature, this device can easily stop transport machinery even without pulling the wire rope.
High Reliability in Compliance with European and International Safety Standards
- Compliant with EN 418, ISO 13850, and JIS B9703
- In combination with a commercially available safety relay unit, this device can be used for stop category 1 or 0.
The lever-type construction allows widening of the detection range of the wire rope’ s pulled movement, to eliminate the chance of false detection due to thermal expansion or stretch/shrinkage of the wire rope. Ideal for outdoor applications as well.
Application Example of Belt Conveyor Protection
This Rope Trip Detector can be installed directly in an upper position on a conveyor.
Principle of Operation
A pull on the wire rope, which is fixed to the operation lever, causes the operation lever to be locked at a position 25 degrees from the upright position, which triggers the emergency stop signal output. Pressing down on the reset lever will bring the operation lever back to the upright position, and will release the lock. When the emergency stop operation is activated by detection, the emergency stop status will be retained until the lock is manually released. (The emergency stop pushbutton operates in the same manner.)
