What is the difference between semi-trailer and full trailer?

The difference between semi-trailer and full trailer is mainly reflected in the following aspects:

Firstly, structurally speaking, a full trailer is connected to a complete trailer compartment at the rear of a regular car through a hook; A semi-trailer is composed of a tractor and a semi-trailer compartment, with the semi-trailer compartment connected to the tractor through a towing seat.

Secondly, in terms of wheel configuration, the full trailer is equipped with front wheels and has two axles; In contrast, semi trailers do not have front wheels and are only equipped with one axle.

Furthermore, in terms of load sharing, a fully trailer locomotive does not need to bear the load of the trailer. Its main function is to provide power to help the trailer overcome road friction resistance; However, in addition to providing power, the semi-trailer locomotive also needs to serve as a support point to bear half of the trailer's load.

In summary, there are significant differences between semi-trailer and full trailer in terms of structural design, wheel configuration, and load sharing. Therefore, when choosing between using a semi-trailer or a full trailer, specific considerations should be taken into account
