The uppermost cage 14 of the row cage 16 is moved up and down in the elevator shaft 12 by winding and pulling out the wire rope 22, and is vertically moved to the floor where a call was made by the user to move to the desired position. Users are transported to the floor. In addition, the row cage 16 of this multi-layer elevator apparatus performs an express operation such as stopping at every 20th floor instead of stopping at each floor, whereby a large number of users can be transported at one time. Since it is not necessary to control the operation of each vehicle, control can be simplified.

Here, a time period during which the usage rate of the user is low is input to the control device 80 in advance. At this time, the infrared sensor 30 detects the presence or absence of a user in the cage 14. When it is determined that there is no user in the cage 14, the hoisting machine 24 is operated to lower the row cage 16 and move it to the standby pit 12A.

Here, the compressor 28 is operated to drive the air cylinder 36 to release the locked state between the connecting member 62 and the arm 48. This allows the top cage 1

In the present embodiment, the cage 14 is made to stand by in an underground pit provided in the underground space. The separated cage 14 may be retracted from the interior of the elevator shaft 12 to the waiting room by a pallet.

The structure for connecting the cages 14 to each other is not limited to that of the present embodiment.
The hooks may be connected or disconnected by driving the hooks with a motor or an electromagnet like a train connecting tool.

Further, when the cages 14 are separated, it is necessary to adjust the balance between the row cages 16 and the counterweights 20. In this embodiment, the weight of the counterweights 20 is reduced in a state where the two cages 14 are connected. It is set to balance with the weight in the. In this way, by maintaining the balance between the maximum load and the minimum load of the row cage 16, the load on the hoisting machine 24 can be reduced.
