Due to different operating conditions, the functions of trailers vary greatly. In terms of tonnage, most of them are concentrated between 3T and 10t; Some special-purpose trailers, such as trailers specially used for moving large equipment in the factory, can reach 25t; There are also some small trailers whose tonnage can be as light as about 1.5T.
