In the standard GB/T 3730.1-2001, the semi-trailer is defined as: “An unpowered road vehicle that can be used normally for the purpose of vehicle traction for its design and technical characteristics. It is used for carrying people and goodsâ€. From this definition, it is not difficult to see that “flight-hanging transportation†is a feature of semi-trailer transportation. The greatest advantage of this mode of transportation is convenience, speed, and economy, which is why the semitrailer occupies the largest proportion of the total number of special vehicles. There are many types of semi-trailers, including van semi-trailers, tank semi-trailers, flat semi-trailers, container semi-trailers, vehicle semi-trailers and so on.
