[0002] Transport vehicles are vehicles specifically designed for transporting personnel, equipment, and goods. Mountain transport vehicles are specifically designed for transporting personnel, equipment, and goods in mountainous or steep terrain. However, to adapt to special terrains such as steep slopes and rugged terrain, mountain transport vehicles have a compact body and small volume, making them unable to transport "oversized, overlength, or overheight" goods. They can only carry scattered and small goods.

[0003] Existing conventional mountain transport vehicles have fixed-size truck beds and racks, which can only carry scattered and small goods and cannot meet the transportation needs of large goods of different sizes. If it is necessary to transport large goods of different sizes, it is necessary to customize truck beds and racks for different sizes of large goods and replace them to adapt to various goods, which is costly and difficult to operate.
