Since the technical threshold for producing trailers is relatively low, trailer manufacturers have sprung up like mushrooms after a rain. Many of them are small workshop-style production models. They buy a few simple equipment, hire a few workers and start production. They also hire many cheap apprentices. The production and labor costs are very low, and the use of inferior parts has become the main reason for the huge difference.
The second is the quality problem. Many parts are not marked. A user who went to X County to buy a trailer and "had no choice but to return" told reporters: Many modification companies still use counterfeit and shoddy parts. The company I went to even told me bluntly that the axle used a fake Fuhua axle.
The after-sales service can't keep up at all. Such vehicles are sold one by one. The original condition of the vehicle was not good, and there was no normal maintenance and service guarantee, which had great safety risks. This unqualified semi-trailer can also change the size at will according to the user's requirements. A heavy truck dealer in Shandong told reporters that it is understood.
In the current freight environment in my country, most users are willing to lengthen and widen the box body. The length of the box trailer body has even been changed from the original four to five meters to nine to ten meters, and some single-layer boxes can be changed to double-layer. Such modified vehicles are often seriously overloaded, and they seriously affect the driver's vision after going on the road. In addition, this kind of private modification does not consider the design performance of the vehicle. The small horse pulling the big cart affects the braking function of the vehicle and is very likely to cause traffic safety accidents.
Through the above introduction, everyone should have a general understanding of low-priced semi-trailers. When purchasing semi-trailers in the future, it is better to choose regular manufacturers. Even if the price is a little more expensive, the quality is guaranteed, and it is safe and convenient.
