Abstract In a container ship, an arm for supporting the containers at positions above the bottom of the container loading space. The arm is pivoted about a horizontal axis so that it may be displaced to a position outside of the location for the containers. A hydraulic cylinder mechanism is provided for displacing the arm, and a slotted connection is provided between the mechanism and the arm so that when the arm is in position within the loading space, the mechanism may be displaced relative to the arm to hook the arm in its horizontal position. The arm has a pin element which projects downwardly from the horizontal position to engage in a hole in the top of the container and prevent lateral movement of the container, the arm serving to hold down the container, and an angle member projecting upwardly from the horizontal position of the arm to receive the bottom corners of the upwardly adjacent container and retain it against lateral displacement.
Apparatus for fixing containers within a location in a ship comprising vertically rotatable arms provided on a supporting body which is installed outside of the container loading location, each arm being provided with an element projecting downwardly when said arm is horizontal and adapted to engage and fix the container positioned in said location below said arm, and guide means projecting upwardly adapted to engage and position another container above said arm against both lateral and downward displacement, and means for rotating the arms upwardly away from said horizontal position in said location including a piston and a hydraulic cylinder pivoted to said supporting body and having a hook mounted on the cylinder and engaging said arm to prevent upward displacement of said arm when said piston is fully retracted, and means connecting the piston to the arm so as to effect lateral movement of the piston and cylinder upon projection of said piston in a direction to raise the arm, so that the hydraulic cylinder is moved laterally in relation to the arm to automatically release the hook from engagement with said arm when the piston is projected to raise said arm.
