When driving on roads with poor road conditions, road vibration excitation will inevitably be transmitted to the connection parts. A certain buffer is required between the container and the chassis to reduce the vibration transmitted to the container. When driving on roads with good road conditions, the container needs to be fastened to the chassis to improve the stability of the container.
