Freight container handling operation monitoring system - allocates destinations on site from control centre for setting containers down

摘要

The crane driver in his cab handles the containers in accordance with a destination and a container number signal emitted from a control centre. A number of destinations are allocated to surfaces on the container site where they must be set down, and the destination of a particular one is transmitted to the cab as an instruction signal. The actual position of the cab is established, and the driver can only handle the container when its position and that of the cab coincide. The crane is then guided along the correct path to the destination, even when rubber-tyred.
