A single self-propelled crane 20 can be selected. In addition, as another method for selecting the self-propelled crane 20 from the self-propelled cranes 20 registered in the unloadable list i1, one crane number is randomly selected from the crane numbers registered in the unloadable list i1. You may adopt the method of doing.

  The crane allocation determination unit 78 transmits the crane number of the selected self-propelled crane 20 to the carry-in side terminal 61 of the gate 60 as transport destination information, generates a job for the selected self-propelled crane 20, and is self-propelled. The job is transmitted to the crane control computer 30 of the crane 20. This ends step S7.

  In the gate 60 shown in FIG. 1, the carry-in terminal 61 receives the destination information from the cargo handling management device 70 shown in FIG. At the gate 60, the destination information is output by the output means 66, and the received crane number is passed to the worker who carries in the container C (the driver of the foreign chassis 100). In the present embodiment, the crane number included in the transport destination information is a number that matches the traveling lane number. For this reason, the driver | operator of the foreign chassis 100 can know the traveling lane number used as the conveyance destination of the container C by receiving conveyance destination information.

  A carry-in worker who carries the container C into the container yard 5 carries the container C to the traveling lane 40 corresponding to the crane number based on the crane number included in the carry-in destination information.

  The crane control computer 30 of the self-propelled crane 20 selected by the crane assignment determination unit 78 sends the job transmitted from the crane assignment determination unit 78 to the main control unit 31 through the wireless device 35 and the input / output unit 36 shown in FIG. Receive at. Then, when the container C arrives at the travel lane 40, the self-propelled crane 20 conveys the container C to the storage area 42 according to the job. Thereby, the container C carried into the container yard 5 is stored in the storage area 42 by the self-propelled crane 20 in the cargo handling operation state (see FIG. 3).
