| Zusammenfassung: | The present invention relates to a diagnostic device for an elevator door. A load-carrying load of a car (20) is detected by a load sensor (204) in each floor. When detecting the car in a non load state, a mobile distance of the car door from a door-opening motion of the car door to a position where a locking mechanism of a layer station door is released is measured by pulse numbers of a pulse generator (203). Based on the measured value, a joggling state of the layer station door and the car door is diagnosed, thereby it is capable of examining at an appropriate moment. |
