Abstract

PURPOSE: To prevent accidents due to earthquake, by detecting the derailment of a counterweight through detectors located near the path of the counterweight and controlling the elevator.
CONSTITUTION: The counterweight 4 is engaged with guide rails 3 so that the counterweight is moved vertically. The detectors 6 having antennae 6a are located at both the sides of the guide rails 3. When the counterweight derails and displaces the antanna 6a, an abnormality alarm is energized to inform the derailement to an elevator control room. Then, a control unit operates to stop the gondola 5. Moreover, an emergency operation unit is energized to move the gondola 5 in a safe direction and then open the door.
