Container handling system

A container handling system, comprising:

• a container yard and a loading/unloading zone,
• an automated stacking crane or a rubber tyred gantry crane configured to move a container between the container yard and the loading/unloading zone,
• the loading/unloading zone is configured to receive a transport vehicle for transporting the container,
• the loading/unloading zone further comprises a wheel stopper for indicating a correct place for the transport vehicle, and a protective structure configured to cover a predetermined section of the loading/unloading zone, the wheel stopper being positioned at a predetermined longitudinal distance from the protective structure,
• wherein the protective structure comprises a sensor configured to detect movement within the predetermined section and to send signals to a controller,
• the sensor is attached to an underside of the protective structure, and
• the sensor or an additional sensor is configured to check correct position of the protective structure in relation to a cabin of the transport vehicle,
• wherein the controller is configured to stop all operations of the container crane in response to the sensor detecting motion under the protective structure,
• wherein the predetermined longitudinal distance is configured to align the protective structure over a cabin of the transport vehicle, and
• wherein the controller is configured to stop a movement of the automated stacking crane or the rubber tyred gantry crane in response to a signal from the sensor indicating an abnormal detachment state of a container from a platform of the transport vehicle.
