Specifically, when a cargo handling command of the container C for the foreign vehicle 20 is transmitted from the management device 40, or when the operator confirms that the foreign vehicle 20 has stopped below the portal crane 30, the display device 37a is displayed. The pre-loading image IBx is displayed.

  As described above, in this embodiment, the operator can compare the foreign vehicle 20 stopped below and the pre-loading image IBx displayed on the display device 37a. Thereby, it is advantageous to check whether the foreign vehicle 20 that has actually arrived has arrived as instructed, and it is possible to prevent the foreign vehicle 20 that is different from the instruction from loading and unloading the container C. Along with this, cargo handling efficiency can be improved.

  In this embodiment, the display device 37a has been described as an example of a monitor. However, as the display device 37a, for example, a display device such as a projector that displays the pre-loading image IBx on a window of the driver's cab 59 may be used. By displaying the pre-loading image IBx directly on the window of the operator's cab 59 in this manner, the operator does not need to monitor the monitor sequentially, which is advantageous for the safety of the loading operation.

  In this embodiment, similarly to the first embodiment, the loading-time image pickup device 57 may be installed on the portal crane 30 and the image IAx during loading may be displayed on the display device 37a installed in the operator cab 59.

  In the above-described embodiment, the control is separately performed by the management device 40 and the control device 43 to reduce the information processing load per one device. However, the control may be performed by one device.
