Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container handling device.

Conventionally, container cargo handling on container ships has mainly been carried out using land-based container cranes.
However, there are only a limited number of ports that are equipped with land container cranes, and in ports that are not equipped with land container cranes, only ships with onboard lifting equipment can handle container cargo. Although derricks or cranes are often used as cargo handling equipment in such cases, the cargo handling efficiency is much lower than that of land container cranes. Furthermore, when cargo handling equipment is installed on a ship, it is necessary to secure a space for its installation, which causes a deterioration in the efficiency of container loading onto the ship.

For example, as shown in FIG. 1, a hull 1 is provided with various tanks, an engine room, a container hold, etc. (none of which are shown) below the upper deck 2, and containers 3 are stowed in the container hold. In ships where containers are mainly stowed on the upper deck 2, a ramp 5 is installed between the quay 4 and the upper deck 2 of the hull after berthing, and a ramp 5 is used to carry containers in and out. A cargo handling method is adopted in which a moving truck 6 is transferred between the quay and the upper deck 2 of the hull. On the other hand, ships of this type where containers 3 are mainly stowed on the upper deck 2 generally have a small freeboard, and as shown in the figure, in some ports, the upper surface of the quay wall 4 has a higher level than the upper deck 2 of the hull. It is often located in In this case, the lamp 5 must be folded into two pieces because the connection between the lamp 5 and the upper surface of the quay wall 4 needs to be smooth. Therefore, a long ramp 5 is required, and the hull 1 must be docked at a considerable distance from the quay, which poses a problem in ensuring the safe mooring of the hull 1.

The present invention allows the use of short ramps regardless of the level interaction between the hull and the quay top;
Furthermore, we propose a cargo handling device that not only ensures safe mooring of ships but also ensures high cargo handling efficiency and container stowage efficiency even in ports without land container cranes. This will be explained based on FIGS. 2 to 7.

Reference numeral 11 indicates a hull, and containers 13 are mainly stowed on the upper deck 12 of the hull 1, and some containers are stowed in a container hold (not shown) below the upper deck 12.
