Most of the trucks we see most on the road are semi trailers. Semi trailers not only pull more goods, but also are more flexible than some other full trailers. Trailers can be used on different tractors, which can improve the use efficiency of vehicles. Different semi trailers have different uses, and some special semi trailers have higher requirements for axles, and even need to customize special axles.
