Document Type and Number:
WIPO Patent Application WO/2024/062534
Kind Code:
A1
Abstract:
This double deck elevator includes: a car device 2 that is capable of moving inside a hoistway 1 in the vertical direction; a control device 5 that controls the movement of the car device 2; and a detection device 200. The detection device 200 includes a first detector 201 that is for detecting the presence or absence of an anomaly in a car movement target device which operates together with the movement of the car device 2. The car device 2 includes an upper car 21 and a lower car 22 that is disposed below the upper car 21 and that is connected to the upper car 21. When the control device 5 performs an emergency operation for stopping the car device 2 at the nearest floor upon receiving earthquake information and then performs a diagnostic operation for diagnosing the state of the elevator, in the diagnostic operation, the control device 5 determines, on the basis of information from the first detector 201, whether or not a normal operation is possible, while moving the car device 2 from one to the other of a raised position at which the lower car 22 stops at the top floor of a building and a lowered position at which the upper car 21 stops at the bottom floor of the building.
