What does the head of a semi-trailer refer to?

Semi-trailer is a kind of model used more frequently in modern logistics transportation industry, which is composed of two parts: tractor and semi-trailer. Usually, tractor-trailers and semitrailers carry separate license plates, with the semitrailer plate having one more character than the tractor-trailer.

Usually owners mention the "locomotive", in fact, is a popular name, refers to the tractor. The tractor is the source of driving power of the semi-trailer. It has driving ability and can drive the semi-trailer through the connecting device. It can also drive independently from the semi-trailer.

The opposite of the front is the "bucket", which refers to the semi-trailer behind the tractor. It is mainly used for loading goods. Generally, it does not have the driving force and needs to achieve driving with the help of the tractor. According to the different bucket, it can be divided into low plate semi-trailer, warehouse grid type semi-trailer, container semi-trailer and so on, respectively for different cargo transportation.

The head of the semi trailer bears the driving function of the vehicle and directly determines the forward power of the vehicle. At present, the price of the semi-trailer locomotive on the market is generally between 250,000 and 320,000, depending on the brand and model selected. There are also many brands in the domestic semi-tractor industry that do well, such as Sinotruk, Jiefang, Shaanxi Automobile, Dayun, Auman, Sany, Dongfeng, Zhongji and Luo Xiang. The owners can refer to them when choosing and buying.

Compared with the front, the price of the semi trailer bucket is much cheaper, generally about 90 thousand. The main components of the bucket include frame, leg, gantry frame, column, suspension, axle, tire, protection, etc. The axle is the key component of the relationship between the bucket bearing performance and braking sensitivity. At the same time, it matches with the tire to maintain the vehicle running.

Nowadays, the lightweight trend is prevailing in the semi-trailer industry, and so is the  trailer axle. More and more brands launch the main lightweight products, aiming to achieve the overall weight reduction of the vehicle through their own weight reduction. However, different from other components, the main function of an axle is load-bearing. How to achieve lightweight without affecting the load-bearing capacity of an axle still requires certain strength and technical foundation.

DARO Heavy Industry Group, as an early axle enterprise in China, has made good achievements in the field of  trailer axle lightweight. Starting from raw materials, DARO's trailer axle is made of one-piece high-quality low-alloy seamless steel pipe with lighter dead weight and better robustness. After 15 precision production processes, Daro Heavy Industry Group has added unique technology. Greatly improve the strength, toughness and extension of the product, while reducing the weight of the product by 10%-25%, fuel saving and efficiency at the same time, for the majority of owners to bring higher operating benefits.
