Testing a speed limiting system of an elevator installation

摘要

In a method or a test device for testing a speed limiting system of an elevator installation, in which speed limiting system in normal operation on occurrence of an impermissible movement state of an elevator cage a cage brake device is activated in that a limiter traction means connected with a trigger mechanism of the cage brake device is braked by a speed limiter, whereby the trigger mechanism of the cage brake device is actuated against a trigger resistance force, the limiter traction means is, when the test is performed, operatively connected with the trigger mechanism by way of a test device, wherein the test device has the effect that for overcoming the trigger resistance force of the trigger mechanism a greater traction force is required in the limiter traction means than when the limiter traction means is directly connected with the trigger mechanism.
