Description

LASHING BRIDGE

The present invention relates to a lashing bridge, and more specifically, to a lashing bridge that can prevent containers from falling over and being lost by supporting loaded containers against external forces acting on the side of the hull.

In general, a container ship is a ship that transports containers, loading large amounts of containers and performing maritime transportation.

On the upper deck of a container carrier, containers are arranged in the transverse direction of the carrier and stacked in multiple layers for safe combination.

At this time, the containers are loaded in multiple layers and are greatly affected by storms and winds. In particular, the hull may shake left and right due to wind and waves, causing the container to overturn, and there is a risk of the container overturning due to strong winds.

To prevent this, container carriers are equipped with a lashing bridge, a structure for the safety of loaded containers, to secure the containers, and the lashing bridge and containers are coupled by a lashing rod.

However, the lashing bridge has the disadvantage that it is erected only between the rows of containers and only supports the load of the containers against external forces acting in the longitudinal direction of the ship, but cannot support the containers against external forces acting in the lateral direction of the ship.

That is, when the lashing rod is disengaged due to an external force acting in the side direction of the ship, there is a risk that the container may fall to the side of the hull and be lost from the ship or the ship may run aground.

Accordingly, there has been a need to develop lashing bridge technology that can safely load containers to prevent them from falling over the side of the hull.
