The control device 21 which has taken in the contents of the barcode slip outputs a gate close command to the gate drive device 23, closes the car 7 and the gate of the hall, and then gives a start command to the electric hoist 9 to cause the car 7 to operate. Up and down to the destination floor nF specified by the barcode.

When the car 7 landed on the designated floor nF of the bar code vote and stopped,
The gate drive device 23 opens the car 7 and the gate of the hall.

Then, an optical signal for permitting work is sent from the optical signal transmitter 29 to the unmanned worker 31 standing by at the entrance / exit of the designated floor.

When this optical signal is received by the receiver 33 of the unmanned worker 31,
The unmanned worker 31 starts operation and lifts the equipment L in the car 7 and carries it out of the car 7.

When the material L is carried out of the car 7, the in-cargo detector 25 transmits a signal indicating that the material is not present to the control device 21, and shifts to the next lifting operation.

Therefore, according to the present embodiment, it is possible to unmannedly determine the transfer floor of the equipment L loaded in the car 7 and automatically transfer to the designated floor.

As a result, it is possible to eliminate the personnel engaged in the operation of the lifting lift 1 at the construction site, improve the efficiency of the vertical transfer work, and put the workers who have contracted the work area into the work of the work area. The work process according to the table can be promoted without delay.

Further, in the embodiment, since the presence detector 25 is provided and the bar code reader 27 is operated only when the car 7 is required to be moved up and down, the work of vertically conveying the material L can be performed more reliably.

Further, the bar code reader 27 can read not only the transport floor but also the type and quantity of the material L, the transportation location, the name of the trader who handles the material L, etc. from the barcode slip. By connecting, it is possible to determine the carrying-in status of the materials and equipment L on each floor, the usage status of the lifting lift 1, and the like, and it is also possible to perform comprehensive management when proceeding with the construction work.

Further, as in the embodiment, by combining with the unmanned worker 31, it is possible to unmanner the loading into the car 7, the vertical transportation, and the unloading at the designated floor.
