- the first and second landing inspection devices 15 and 18 are accommodated in a landing button device (not shown) provided on the landing wall, and are normally not exposed to the landing. . However, when the operator removes the front plate of the landing button device, the first and second landing inspection devices 15, 18 are exposed to the landing.
- the control device 11 selects and validates only one of the operations.
- the first landing inspection device 15 is positioned as a main landing inspection device
- the second landing inspection device 18 is positioned as a secondary landing inspection device. Therefore, when both the first and second maintenance operation units 16 and 19 become operable (maintenance mode), the operation for the first maintenance operation unit 16 becomes valid and the second maintenance operation unit 16 becomes effective. The operation for part 19 is invalidated.

- the driving device 2 is disposed in the hoistway 1, and is disposed closer to the driving device 2 than the second maintenance operation operation unit 19, and thus the first landing inspection device 15 performs an emergency operation. Since the operation unit 17 is provided, the transmission path of the operation force from the emergency operation unit 17 to the drive device 2 can be shortened, and the drive device 2 can be operated more reliably.
- the driving device 2 is disposed at the top of the hoistway 1 and the first landing inspection device 15 is disposed on the top floor, so that the driving device 2 can be operated more reliably. At the same time, it is possible to visually check the drive device 2 through the inspection window.
- the emergency operation unit 17 is provided only in the first landing inspection device 15, the overall configuration can be simplified and the reliability can be improved. Furthermore, the control device 11 selects and validates only one of the operations when both of the first and second maintenance operation operation units 16 and 19 are input, so reliability is improved. Can be improved.
- FIG. 2 is a side view showing an elevator apparatus according to Embodiment 2 of the present invention.
- the second landing inspection device 18 is provided with a second maintenance operation unit 19 and a second emergency operation unit 20 for moving the car 5 in an emergency.
- the configuration of the second emergency operation unit 20 is the same as that of the first emergency operation unit 17.
- Other configurations are the same as those in the first embodiment.
- the rescue operation of passengers in the cage 5 can be provided on the top floor even if the emergency operation section 20 can be provided in the second landing inspection device 18 that is not limited to the first landing inspection device 15 alone. It can be carried out from the bottom floor without moving, and work efficiency can be improved. Note that the second landing inspection device can be provided with only the second emergency operation unit without providing the second maintenance operation unit.
- the top floor is the first stop floor, but it may be another stop floor.
- the second stop floor need not be the lowest floor.
- the first stop floor is a stop floor close to the drive unit as described above, the work efficiency of passenger rescue work and the like will be further improved.
- the entrance floor with the entrance to the building is the second stop floor, the work efficiency of maintenance work, etc. will be further improved.
- the first maintenance operation unit 16 has priority over the second maintenance operation unit 19, but the first operation operation unit 16 may be given priority.
- the first and second maintenance operation units may be provided with an indicator that displays whether the other party is in use.
- the driving device and the control device are arranged at the upper part in the hoistway, but they may be arranged at other positions, respectively. Also in this case, as described above, it is preferable that the first hall inspection device having the emergency operation unit is arranged closer to the driving device than the second hall inspection device.
- the elevator system as a whole may be provided with more than 3 forces with two landing inspection devices.
- a second landing inspection device may be provided at the landing on one entrance floor and a third landing inspection device may be provided at the landing on the other entrance floor.
