Lowbed semi-trailer is a very popular transportation vehicle. The height of a lowbed semi trailer from the ground is 1.25 to 1.3 meters, so its height from the ground is lower than that of other semi trailers. Because of its low height, its center of gravity is also low. And the lower its center of gravity, the better its stability. The ability to carry high cargo and pass through overhead obstacles is also strong. Lowbed semi trailers are commonly used in mechanical transportation. Used to transport some ordinary machinery and forestry machinery.
