The hinge pin is the component that allows the door of the container to pivot open and closed. It serves as the central axis around which the door rotates, enabling easy access to the interior of the container. The design of the hinge pin is critical as it must support the weight of the door and withstand repetitive use without degradation. A well-functioning hinge pin ensures smooth operation and proper sealing of the doors when closed, which is essential for maintaining the integrity and security of the cargo within the container. Other components, like the locking bar or J-Bar, play roles in securing the door once it is closed, but they do not facilitate the opening and closing motion itself. The threshold plate, typically located at the bottom of the container, serves to elevate the door and may assist in sealing but does not contribute to the actual pivot movement of the door.
