PROBLEM TO BE SOLVED: To provide a temporary restoration operation apparatus for a machine-room-less elevator installed in a base-isolated building, which makes it possible to increase an upper limit of an earthquake at which a temporary restoration operation during the earthquake is executable.SOLUTION: A elevator temporary restoration operation apparatus 30 during an earthquake is disposed in a machine-room-less elevator 1 installed in a base-isolated building and temporarily restores the machine-room-less elevator 1 on the basis of a low Gal and a high Gal to be detected during occurrence of an earthquake. An earthquake sensor 4 for the temporary restoration operation that detects the high Gal is disposed at a top of a hoistway 8. A reference value when the earthquake sensor is disposed in an elevator machine room can be set as a value of the high Gal, thus making it possible to increase an upper limit of an earthquake at which the temporary restoration operation during the earthquake is executable in the machine-room-less elevator installed in the base-isolated building.SELECTED DRAWING: Figure 1 |
