The difference between a full trailer and a semi-trailer

Different from a semi-trailer, a semi-trailer is a trailer whose axles are placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and are equipped with a hitch that transmits horizontal or vertical forces to the tractor! Generally, there are two axles for trailers and one axle for semi-trailers. Semi-trailer refers to a vehicle that has no power itself and is jointly carried with the main vehicle and relies on the traction of the main vehicle.

To put it simply, the full trailer is connected to the front truck with a hook. In long-distance transportation, it is very common to hang a carriage (or more than one) behind the truck, which is a full trailer. The semi-trailer is connected to the traction seat of the tractor through the traction pin. The common container transport vehicle is a typical semi-trailer, and the rear loading part is the semi-trailer.
