Accordingly, when the hull is shaken from side to side or a strong wind is applied due to a windstorm, there is a risk that the container is separated from the hull or overturned.

In order to prevent this, the container ship is provided with a lashing bridge for securing the containers stacked on top of the hatch cover. In general, the lashing bridge is a structure disposed along the width direction of the hull, and includes a plurality of vertical support structures and a plurality of horizontal support structures provided to be movable by a worker.

Such a lashing bridge requires strength to withstand the large load transmitted from the container, and since the load can be transmitted in various directions according to the shaking of the hull, a structure that can stably absorb the load applied in various directions is required. do.

Furthermore, since the lashing bridge is also a facility mounted on the hull and affects the weight and center of gravity of the hull, a method is required to secure and support the container stably and at the same time promote structural stability and efficient operation of the container ship.
