PROBLEM TO BE SOLVED: To shorten inspection time for determining whether or not, there is any door opening/closing abnormality by eliminating operator's cage transfer during door inspection of a one-shaft multi-elevator.SOLUTION: An elevator door inspection device is applied to a one-shaft multi-elevator, and includes a control unit for inspecting door opening/closing abnormality. The control unit 11b allocates, after switching of an operation mode from a normal operation mode to a maintenance inspection mode based on an inspection operator's operation, a plurality of cages 2 to the end floor of an inspection area allocated to each of the plurality of cages 2 so as not to overlap each other, moves each cage to all the floors in the inspection area, and sequentially opens/closes a cage door device 5 and a landing door device 4 in an interlocking manner, thereby inspecting the presence/absence of door opening/closing abnormality at all the floors.SELECTED DRAWING: Figure 3 |
