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. Flatbed semi-trailer and bulk cargo semi-trailer: these two kinds of semi-trailer are the most common on the road. The standard length of flatbed semi-trailer is 13 meters and the weight is only 6-7 tons. 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 1310mm, which refers to the distance between bilateral tires.
2. Lowbed Trailer: low flat trailer is a vehicle specially used to transport engineering operations, such as excavator, roller, hook machine, loader, bulldozer and other vehicles. 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. Generally, the load of single axle of low flat axle is 13-16 tons
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 also 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.
