Abstract
A system and method for reducing time delays while loading and unloading a cargo ship includes scanning and using an identifier to determine content and destination information for a cargo container, using a trolley crane and spreader to move the container between a ship and an elevator, and loading and unloading containers between a horizontal conveyor and a trailer with an orthogonal coordinates crane. The container is moved up and down on the elevator between the trolley crane and spreader and the horizontal conveyor. The horizontal conveyor moves the container between the elevator and an orthogonal coordinates crane and spreader. The two cranes move the container more efficiently and rapidly, and the system permits some loading and unloading to occur in the absence of the cargo ship or trailer. The elevator and conveyor move the containers more quickly than a trolley crane alone, and can be automated.
