In recent years, van semi-trailers have continued to innovate and advance with the technology of car body materials. In addition, lightweight technology has also been running through the development of van trailers. The development speed of van semi-trailers is relatively fast, and the industry standards introduced recently have provided an opportunity for the development and application of van semi-trailers.
In the future, China's van semi-trailers have been promoted on a large scale. In particular, GB1589-2016 has clearly pointed out that the current normal operation of the slab, flat and warehouse-type semi-trailers is up to 13 meters, but other semi-trailers. The maximum length is 13.75 meters. The national vehicle regulations limit the length of the bar, flat and semi-trailer from the top design. In addition, the length limit of semi-trailers such as van semi-trailers is relaxed to 13.75 meters, which is also intended to encourage its development. .
