Abstract
A self-propelled container handling apparatus handles a container in a container yard. The container handling apparatus reads an identification code borne on the container and senses a position of the container to be handled. On the basis of the container identification code read by the container handling apparatus and the container position sensed by the container handling apparatus, the inventory data for the containers stored in the container yard are updated.
