What Is A High Quality End Dump Semi Trailer Like
What is an end dump semi trailer?
When most people hear the word “dump semi trailer“, they think of the end dump semi trailer. As the name suggests, the end dump semi trailer unloads the goods from the rear, the “box” is lifted into the air, and the goods are dumped from the rear end by gravity, which is the end dump semi trailer.
With the development of economy, the demand of end dump semi trailer is increasing. So what good characteristics should a high quality end dump semi trailer have?
First of all, the structural design of high quality end dump semi trailer should be reasonable, and the center of gravity of chassis should be as low as possible. According to the load, cargo type, road conditions and driving habits of the driver, the system is planned and designed to meet different use needs. The materials should be real. The same steels on the surface are actually different, including manganese steel and ordinary carbon steel. Different materials, durability and quality, and the weight of the body will be different, but the cost of high quality end dump semi trailer will also increase.
Manufacturing technology and painting of high quality end dump semi trailer
The processing technology of end dump semi trailer should pass the test. With the popularization of mechanical automation, in the process of vehicle processing, many factories have realized basic automatic operation, and the production technology has been greatly improved.
In addition, after welding and forming, surface sandblasting and derusting are required to better increase the adhesion of paint. The paint spraying shall be uniform and the coverage shall be comprehensive. The paint can also be divided into alkyd paint and high grade polyurethane paint. Considering the structural characteristics of semi trailer, the spraying mode is mostly manual and mechanical semi automatic mode. In recent years, many manufacturers have also begun to try new electrophoretic coatings.
In order to match the reasonable lightweight of the end dump semi trailer, the semi trailer industry also follows the standard of light pulling and more goods. However, considering the particularity of the working nature of the end dump semi-trailer, we must not lighten blindly. In addition to selecting the body structure of high strength materials, the application of aluminum alloy accessories is also a good choice, such as aluminum alloy rim, toolbox, legs, mud tiles, etc. the overall weight is reduced by about 400 kg.
The quality of key parts shall be reliable. For example, the price of axles, domestic axles and domestic joint venture brand axles is very different from that of imported axles. Practice has proved that it is right to give goods for every penny. The installed tires need to be guaranteed. Dump trucks and trailers are generally equipped with 12.00 vacuum tires. High quality tires are an important guarantee for driving safety. Choose brand tires to ensure driving safety. The hydraulic lifting system shall be stable, the oil circuit design shall be reasonable, and the lifting of oil cylinder shall be synchronous.
