[0002] In the field of logistics transshipment, especially in transshipment situations where containers need to be placed on tooling for stacking, since the bottom height of the tooling is relatively low, a low-profile rail vehicle is required to deliver the container and lift it up to allow it to be removed from the tooling and then moved. However, the direction of the container is not fixed at the factory site, which requires the vehicle body to have an angle rotation function, such as a 90-degree rotation, and then place the container on the tooling, lower it and continue to carry the next container.
