The operator runs the trolley over the ship to lift the container cargo. Once the spreader latches (locks) on to the container, the container is lifted and moved over the dock and discharged on a truck chassis or trailer to then be taken to the storage yard. Containers can also be lifted from the chassis to store (load) them on to the ship.
