This invention discloses an M-shaped automated container terminal loading and unloading
system, including quay cranes, a container
yard, and rail-mounted gantry cranes. The quay cranes are located at the
front edge of the terminal. The container
yard is vertically located behind the rails of the quay cranes and contains multiple container zones. Each container zone contains at least one rail-mounted
gantry crane. Every two container zones form a group, and the rail-mounted gantry cranes within the same group are arranged back-to-back. An external lane and an internal lane are sequentially located outside the rail on one side of the
cantilever end of each rail-mounted
gantry crane. This invention also discloses an M-shaped automated container terminal loading and unloading method. This invention improves the
utilization rate of the container
yard and increases the container stacking area. Simultaneously, the use of a single
cantilever rail-mounted
gantry crane reduces the volume and weight of the container yard equipment, thus reducing equipment investment. Furthermore, the external
truck lane is located outside the rail of the
cantilever rail-mounted gantry crane, avoiding safety hazards.
