After decades of development, domestic highway transportation has a very mature industrial chain. National standards have been established for various technical indicators, such as the manufacture of complete trailers and the formulation of standards for trailer accessories. Semi trailer axle is the most important part of trailer accessories, and the axle also has certain parameters and models.

Semi trailers for different purposes will use axles of different models and sizes. The axle used by special vehicles is a special axle. Let's first take a look at the axles used by semi trailers with a large number of vehicles on the market.

1. Flat panel semi-trailer and high hurdle semi-trailer: these two semi-trailer are the most common ones on the highway. The standard field length of flat panel semi-trailer is 13 meters and the weight is only 5-6 tons. They are light-weight semi-trailer with lightweight design. However, some enterprises will have special design when manufacturing, which can lengthen the flat-panel Trailer. The standard length of Gaolan semi-trailer is 13 meters, some of which will reach 17.5 meters. Gaolan semi-trailer is widely used and suitable for long-distance transportation. It is generally used to transport vegetables, clothes, household appliances and other daily necessities. The axles used by these two semi trailers are generally standard 13 ton axles, and some owners will be equipped with 16 ton brakes to enhance the braking performance of the axles. The track width of standard axle is 1850mm, which refers to the distance between bilateral tires.

2. Low flat Trailer: low flat trailer is specially used to transport engineering operation vehicles, such as excavator, roller, hook machine, loader, bulldozer and so on. The axle used by the low flat semi-trailer is a low flat axle specially produced for it. Its characteristic is that the chassis is relatively low and small-size tires are used together, which is very convenient for engineering vehicles to get on and off. The general single axle load of low flat axle is 10-13 tons, the wheelbase is 1920mm, and the size of axle tube is 127mm.

3. Container semi-trailer: as the name suggests, container semi-trailer is specially used to transport containers. Its design is relatively simple. The semi-trailer looks like a flat car and can only hold containers. Generally, the axle length used by container semi-trailer is standard, and axles of different tonnage will be used according to its load. If the normally pulled container is relatively heavy, the axle of 16 tons or 20 tons can be used.

4. Dump semi-trailer: it mainly transports bulk goods such as coal, residue and grain. The dump semi-trailer is very convenient for cargo loading and unloading. This semi-trailer has strong bearing capacity and will never deform. The processing technology is very advanced and durable. The axles used are high-strength and high bearing capacity axles tested by the market, generally 16 ton or 20 ton axles.

Shandong Darong Machinery Co., Ltd. specializes in the production of various axle axles. It was established in 2001 with strong technical reserve and supports customized axle axles. The company has a professional production workshop of more than 60000 square meters and a special quality inspection center to ensure that each axle delivered from the factory is qualified products. At present, the company produces various types of semi-trailer axles, such as eccentric axle, American axle, German axle, three line six axle, five line ten axle, etc.
