Kiepe HEN Pull Rope Switch Belt Conveyor - Pull Rope Switch HEN - Kiepe HEN 002 91.043 450.002
APPLICATION : Kiepe pull rope emergency stop switches are used according to DINEN 620 requirements together with functionally suited accessories, largely consisting of pull rope, tension springs and eyebolts, for the assembly of emergency stop systems at fixed belt conveyors. The Kiepe emergency stop systems meet the requirements of international safety standards to ensure safety at work and to prevent damage and destruction of the machine (BGI 710).
OPERATION : The emergency stop function is implemented with positive making normally closed contacts according to the closed circuit principle. The direct operating switching mechanism inside the switch is of snap action and is actuated when the pull rope is either pulled in any direction or if the rope breaks. After the triggering of the emergency stop function, the switching mechanism locks in the off position. Through manual actuation of the blue reset lever locally at the pull rope switch the switching mechanism is reset to the operating position and the belt conveyor is prepared for start-up. The resetting of the switching mechanism may not start the belt conveyor. With the Kiepe HEN type pull rope switch, the pull rope is symmetrically tensioned on both sides of the red release lever and thus a complete compensation of the rope forces at the release lever is achieved. For this reason, double-sided pull rope switches of the HEN design are especially suitable for outdoor use with large changes of the ambient temperature (summer – winter) of up to60°C and more.
