The main feature is the design, because the dread is divided into two categories:
installed on a passenger trailer where only one axis is used. The cargo of such a trailer is insignificant for transportation of small cargoes, usually household. They are rarely used by such a trailer, so the technical parameters with such a pulp will be more than enough. From the disadvantages of this chop that can occur when riding off -road.
This design variant serves to transport medium heavy cargoes and is usually installed on a two-sided assembly. It is quite resistant on the road, which avoids unwanted swinging without changing the smoothness and ease of movement on irregularities.
in the a-shaped spare parts there is still an elongated type. It is the same design, only part between the trailer and the car on which the connection lock is installed, a little overcome. Quite a comfortable version of the workpiece used to transport large cargoes and is operated in boat trailers.
Another characteristic feature that is often used in a variety of different shapes is height adjustment. Convenient to use a single trailer for different cars with different heights for connection. In principles, this option is universal, which creates great demand among users.
