As described above, according to the embodiment, when the cage 20 is further inspected and raised after the top securing limit switch 3 is cut off and the cage 20 is stopped, the cage 20 is stopped every second and the top is close. It can call attention to that.

Since the inspection speed is generally about 10 m / min, the traveling time per second is about 150 mm, which is a sufficient value for danger notification. <Modifications> The present invention is not limited to the above-described embodiment.
It can be modified as follows. After the top securing limit switch 3 is turned off, an alarm can be given to the inspector 1 by always stopping at the door openable position on the top floor. This is because the position where the top securing switch 3 is turned off is about 500 mm below the top floor,
It stops without fail after traveling and safety can be ensured.

The inspection speed changing means according to the second embodiment and the intermittent operation means according to the third embodiment are both constituted by the RAM 13 and the CPU 11 in the control device 7, but are not limited thereto.
