How do shipping container trailer work?
Work process of shipping container chassis trailer:
Container loading: Containers place on the chassis using a crane or container side loader.
Locking mechanism: Twist lock install at the four corners of the container, and these locks lock with the container.
Truck transportation: The chassis used for transporting containers is connected to the tractor unit through a fifth-wheel connector for transportation.
Unloading: After reaching the destination, the twist lock will unlock, and then the container will unload.
This simple design enables rapid loading and unloading, and can achieve seamless connection between different transportation methods, thereby saving time and reducing handling costs.
