6×4 tractor
Co-extrusion polyolefin elastomers (POE) abrasion resistant inner layer plastic composite pipes is characterised by taking co-extrusion thermoplastic polyolefin elastomers as the abrasion resistant inner layer, using a combination of steel wires (or glass fiber) reinforcements and high-density polyethylene. In addition to good workability and physical and mechanical properties as HDPE pipes, such pipes have good wear resisting performance. Co-extrusion abrasion resistant composite pipeline is a kind of anti-abrasion pipe with high cost-effective performance.

As the saying goes, there is no best but better. On the road to lightweighting heavy trucks, this sentence can be read as: No lightest, only lighter.
8.8 tons, 8.5 tons, 8.2 tons, 8.1 tons, 7.9 tons...... It can be said that under the catalysis of the governance of the New Deal, the heavy truck manufacturers are spared no effort in the 6×4 traction for heavy-duty transportation markets such as coal transportation and LTL transportation. Lightweight car to seek new breakthroughs.
Recently, the Ministry of Industry and Information Technology publicized the new vehicle products for which the 290th batch of "Announcement of Road Motor Vehicle Manufacturing Enterprises and Products" (hereinafter referred to as the announcement) was filed. The first commercial vehicle network made statistics on the weight of the 6×4 tractors in the announcement. Want to know the current weight of the 6×4 tractor's mainstream weight, and how lightweight is it? Please look down. 
Note: The statistics in the above table are the statistics of the minimum curb weight (ie the lowest weight) of different model models corresponding to different product names in the announcement.
Lightweight models increased 8.5-8.8 tons still the mainstream <br> <br> above table can be seen in 290 batches announcement, there are five heavy truck business launched 15 new models 6 × 4 tractor. Among them, the FAW Liberation Diesel Tractor (product model CA4250P1K2T1E5A82) has the lowest self-weight, only 7.4 tons, while the other two tractors have the lowest self-weight below 7.9 tons.
With the exception of FAW Jiefang, in the announcement of this batch, the weight of the tractors of CNHTC and Liuzhou are also below 8 tons. Among them, the minimum self-weight of heavy-duty trucks and diesel tractors and dangerous goods tractors is 7.8 tons; the minimum self-weight of Liuchang-long tractors is 7.6 tons.
However, compared with the lightweight model, the 8.5-8.8 tons of 6×4 standard tractors still dominate the market. Of the 15 models in the statistics, there are still 9 models weighing between 8.5-8.8 tons. For example, the minimum self-weight of Auman semitrailer tractors and dangerous goods semi-trailer tractors is 8.8 tons and 8.5 tons respectively; the minimum self-weights of SAIC Hongyan semi-trailer tractors, container semi-trailer tractors and dangerous goods semi-trailer tractors are all It was 8.8 tons; the natural weight of the two natural gas traction vehicles was 8.68 tons and 8.8 tons, respectively. 
From the above figure, it is not difficult to find that in this announcement, the proportion of 6×4 standard tractors with a weight of 8.5 tons or more is 60%; the proportion of 6×4 lightweight tractors with a weight less than 8.5 tons is 40%; It can be seen that the lightweight products of 6×4 tractors are rapidly increasing.
The amount of change required qualitative heavy truck lightweight long way to go <br> <br> have to say, with the official announcement of the new national standard GB1589 and the new version of "overloaded vehicles traveling road regulations," the implementation of, and over a six-axis road cargo vehicles suffered regulations The major "debris flow" and usher in the fact that "the most stringent rule in the history" has led to the continuous introduction of lightweight 6x4 tractors.
The new regulations stipulate that the 6×2 double-axle tractor has a weight limit of 46 tons and the 6×4 tractor has a weight limit of 49 tons. This is like a "great sunny day" for the coal transportation market that links the country's economic lifeline. However, the era of 55 tons has passed and the advantages of the 6×4 tractor have been fully demonstrated. In the face of the new regulations, various manufacturers have been making constant efforts to balance the weight of the vehicles in order to balance as many tons of cargo as possible. For a time, the heat of “lightweight†rose linearly, and new light weight tractors “showed up†in succession. 
However, it is worth noting that in the lightweight “expansion periodâ€, some lightweight products currently on the market are more often achieved by simply subtracting some configurations. This is not truly lightweight. As we all know, truck lightweighting is a systematic project involving the entire vehicle, engine, suspension and other fields. Through the use of new technologies and new materials, we can achieve overall optimization without reducing the overall carrying capacity.
The quantitative change is to adapt to market demand in the short term, and qualitative change is the focus of lightweight reform. It can be said that the weight reduction of China's heavy trucks still has a long way to go.
