Most of the trailers we usually see are three axle. According to the type of trailer, they can be roughly divided into different types of semi-trailer, such as rail car, warehouse grid car, van trailer, tank semi-trailer and so on.

Fence semi-trailer is mainly used for: the length of general fence semi-trailer is 11 meters, 13 meters and 17 meters. Now many trailer manufacturers are pursuing lightweight design. The weight of general 13 meter fence semi-trailer is only about 6.28 tons. High strength steel is used: the materials of web, base plate and key parts are imported steel. The product quality is qualified and the self weight is light, which can improve the loading rate.

Bin grid semi-trailer: it is a semi-trailer designed with fence structure at the loading part, which is mainly used for the transportation of by-products or other light goods. The design process of the fence fully considers the user experience, reasonable design, simple structure and convenient disassembly. The weight of the vehicle is reduced under the condition of meeting the load demand. The 13 meter bin grid semi-trailer is only 6.68 tons.

Tank semi-trailer: tank semi-trailer is divided into oil tank truck, concrete mixer truck, hazardous gas semi-trailer, dust particle and bulk cement semi-trailer. The tank body is specially designed and adopts advanced processing technology. The chassis is the trailer chassis specially used by major manufacturers, and the technology is guaranteed.

Van semi-trailer: it is mainly used for the transportation of household appliances, light textile goods, coal, gravel and other goods. Van semi-trailer has very strong bearing capacity, high safety factor, durability and advanced manufacturing technology. The semi-trailer frame is a through beam structure, the longitudinal beam adopts a flat or gooseneck structure, and the frame adopts shot blasting treatment, which has strong anti rust ability.

The above are the types of semi trailers often encountered. Let's take a look at what special semi trailers look like. Sometimes, for the convenience of transportation, the semi-trailer will have semi-trailer with different self unloading structures such as backward tipping and rollover. In order to meet the needs of transporting large goods, there are semi-trailer with different tonnage such as three lines, six axles, five lines and ten axles.

Rollover dump semi-trailer: in recent years, rollover dump semi-trailer has become very popular, and the number of manufacturers has increased from 281 to 426, with a very fast growth rate. The reason why rollover dump trucks are so popular is mainly due to the implementation of the new national standard, which stipulates that the three-axle barrier truck and warehouse grid truck can only use disc brake and air suspension, In this way, the purchase cost of many original fence car users will increase a lot. Therefore, many users of the original rail cars and warehouse grid cars will turn to the disc brake bridge and air suspension, and it will be very convenient when unloading.

Three line six axle, five line ten axle and other trailers: This semi-trailer is specially designed to transport large goods with strong load capacity. For example, there are 24 tires of three line six axle semi-trailer, which can carry at least 80-200 tons. The heavy cargo transportation axle will also be divided into 9,5m, 13m, 16m, 20m and other different axles. The three-line axle can carry 49 tons. The load of five line ten axle trailer is about 200 tons, and the load of each axle is 20 tons. The more axles, the greater the load. The axles of these axles are customized special axles. From raw materials to manufacturing process and assembly, they are designed to strengthen the load.
