How is a hinge assembly typically constructed in a container?

The construction of a hinge assembly in a container is primarily done by integrating features that ensure durability, strength, and secure connectivity between the container doors and the structure of the container. The correct answer highlights that the hinge is constructed with a blade connecting to the door and a lug integrated into the corner post. This design allows for a robust mechanical connection that can withstand the rigors of handling and transportation, ensuring that the doors can open and close securely while maintaining the integrity of the container.

This method of construction is advantageous because it minimizes the number of moving parts, reducing the potential for failure and wear. The blade and lug design prevents misalignment and provides a stable hinge point, which is critical for the long-term functionality of the container doors. Additionally, such attachments are typically fabricated from high-strength materials that can endure external forces and environmental conditions, thus enhancing the overall safety and efficiency in operations.

In contrast, the other options incorporate methods that are not commonly used in the construction of container hinges. For instance, a removable pin and bolt arrangement might not provide the same level of durability needed for container operations. Rubber gaskets and adhesives are typically used for sealing rather than structural connection, and screws and metallic hinges may not offer the robustness required for the heavy-duty demands
