Method of securing freight containers on deck of ship, and spring lashing bar, space adjuster and securing system used in the method

摘要

The present invention provides a method of securing freight containers on a deck of a large ship, and a spring lashing bar, a space adjuster and a securing system used in the method. In the method of the present invention, a movable lift is installed on a rail provided on a lashing bridge so as to be movable in a horizontal direction and a vertical direction. Freight containers are aligned with each other using tensile force generated in a horizontal direction by a container aligning device provided on a work table provided on the movable lift. The freight containers are coupled to each other using twistlocks in a vertical direction. Subsequently, adjacent left and right containers are coupled to each other using couplers and variable type coupling devices such that the freight containers are integrated with each other along an entire width of the ship or some width thereof.
