What are the common types of semi-trailers?

A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. drive. The load of the semi-trailer needs to be borne by the semi-trailer and the main vehicle together, and it needs trailer axle to be balanced with the help of outriggers after being separated from the tractor.
