A vehicle inspection device includes a storing part and a diagnosing part. The storing part is configured to store operation information in response to operations of vehicles to transport and load/unload an article along a transfer path. The diagnosing part is configured to compare the operation information stored in the storing part with a reference operation information of a vehicle to diagnose symptom of abnormality in the vehicles.

An arrangement of a gantry lifting device for handling containers, in particular ISO containers, having a sensor device for the navigation of the gantry lifting device and having a clearance profile which is formed such that the gantry lifting device can move across a container, and of a row of spaced-apart marking elements such that the gantry lifting device can be moved along the row of marking elements by means of raster navigation, where the row of marking elements can be read by the sensor device of the gantry lifting device. The sensor device, in an operating position, is arranged outside the clearance profile on the gantry lifting device so as, in the operating position, to read the row of marking elements for the navigation of the gantry lifting device, where the row of marking elements is arranged next to the clearance profile of the gantry lifting device.
