Overloaded to determine the weight of heavy trucks


“This year's young quantified vehicles are definitely a bright spot for sales, and there are a lot of users for lightweight vehicles.” Yang, manager of Shanxi Datong Yifu Trade Co., Ltd., happily told commercial car news reporters.

Product advantages

The reason why sales are hot is because lightweight vehicles can bring real benefits to users. "Assuming that the 3-axis light railcars equipped with CIMC standards are used as examples, the number of used domestic ordinary steel rolling stock is about 8 tons, and that of domestically produced high-strength steel is about 6.3 tons, which can reduce self-respecting weight to 1.7. About 10,000 tons, the same type of used imported high-strength steel is 5.9 tons, which can reduce the weight of about 2 tons.After implementing the toll-by-weight, the total vehicle weight can not exceed 55 tons, therefore, the weight is less 2 tons, and each time Dora about 2 tons of goods, a year is a significant profit." Zhang Huayu, a person in charge of CIMC vehicles (a pseudonym) said.

In addition to being able to transport more goods, lightweight models can also reduce expenses. According to Jiang Xiaodong, chairman and general manager of New Hongchang Group, “The user used light weight dump trucks to pull more goods and increase profits, while reducing the maintenance costs of tires and accessories and extending the service life of vehicles. Therefore, lightweight vehicles were received by Shanxi users. "This year, the new Hongchang Group adopted the 7.3m lightweight 6x4 dump truck of high-strength hot-rolled steel and achieved a good sales performance in the Shanxi market.

In terms of product promotion, lightweight vehicles are still in the primary development stage. In order to seize this blue ocean, steel and other raw material companies have also given special incentives to special vehicle companies. “Taking a dump truck as an example, we will control the use of reduced-strength high-strength steels under ordinary steel usage fees. After all, the use of high-strength materials may increase the processing costs and replacement costs of welding materials for auto companies. We hope to use this to give incentives to special vehicle companies to use lightweight materials, said Li Dongjie, sales center of Baosteel.

"In order to open the market, we have also sacrificed part of the profits. CIMC vehicles are only priced at 10,000 to 15,000 yuan more than light rail cars," said Zhang Huayu.

Market improvement is small

There are such cost-effective sales, what sales? In order to take the lead in "lightweight" "small hill", all special car companies have launched their own lightweight products. CIMC Vehicles has launched a full range of products that have achieved lightweight design and production, including semi-trailer series, semi-trailer trucks, semi-trailer trucks, semi-trailer trucks, semi-trailer trucks, and semi-trailer trucks. Hanging tank car series. "Our lightweight products basically cover all models of dump trucks," said Jiang Xiaodong.

However, the sparkling sales of light-weight models in Shanxi did not set off a national trend. Zhang Huaxi said that currently, CIMC lightweight vehicles can only account for about 20% of sales. Jiang Xiaodong also said that in areas other than Shanxi, “it is not lightweight,” and users’ queries on light weight bearing capacity have been difficult to resolve.

Special-purpose vehicle companies generally use high-strength steel to replace ordinary steel, the surface of the steel becomes thin, but the bearing capacity is unchanged. "However, seeing is true, the user sees only the thickness of the steel plate, and can not see the material structure and strength, so the user has ideological obstacles to purchase." Zhang Huayu said.

At the same time, light weight models are indeed inferior to ordinary models in terms of bearing capacity. "Under full load or light overload, there is no problem with lightweight vehicles, but if it is several times as overloaded as that, lightweight vehicles are indeed inherently inadequate. The reason why Shanxi's lightweight vehicles are selling well is mainly due to Shanxi Coal Mainly, the proportion of coal is low, not too heavy, the user has confidence in the carrying capacity of the vehicle.” Jiang Xiaodong said.

Policy is the wind vane

The bigger problem comes from super cure. Ironically, the rise of light weight is to cater to the rule of super, and light weight encounters the current embarrassing situation and has a close connection with rule super.

“In addition to overloading dump trucks in Shanxi Province, which are already strictly prohibited from being overloaded, the overloading of dump trucks is still difficult. Some provinces and municipalities saw the standard vehicles during the day and they all became overloaded vehicles at night; some provinces did not avoid even during the day. The situation where a vehicle pulls more than 100 tons is very much. It is much more than that, and it earns much more. The lightweight model obviously cannot adapt to this kind of work intensity." Jiang Xiaodong said.

“The same is true in the tractor market. In provinces where weight-based tolls have just been implemented, ultra-superiority has been particularly strict, and light-weight models are relatively easy to sell; in certain areas where weight is charged for several years, some local owners have passed “sugar cannonballs”. The opening of a green channel for overloaded vehicles will make it difficult to improve the sales of lightweight vehicles. It is precisely because of such law enforcement flexibility and double standards that lightweight models cannot be widely promoted,” said Zhang Huaxi.

“At present, China’s super highways are very strict, and the lightweighting of such vehicles should be the trend of the times. Enterprises can safely design vehicle structures according to such transportation conditions, but they can’t put an end to the phenomenon of overload in some local markets. It is difficult to have a kind of A product and a marketing policy can cover the entire market. As an enterprise, it cannot be completely bet on light weight.” Jiang Xiaodong thinks.
