With the successive introduction of policies such as air pollution prevention and control, fuel consumption limits, internal combustion engine energy conservation and emission reduction, and motor vehicle emission upgrades, great pressure has been put on the automobile industry that is in "difficulty" in the process of energy conservation and emission reduction, but at the same time it has also put Lightweight vehicles bring development opportunities.
Everyone knows that aluminum trailers are light in weight and beautiful in appearance. The beautiful appearance of aluminum trailers can also attract the attention of many trailer users. At the same time, the light weight can also significantly reduce fuel consumption. According to statistics, for every 10% reduction in the weight of a load-carrying trailer, fuel consumption can be reduced by 6% to 8%. Calculated based on the standard car body, the aluminum trailer can reduce the weight by 3 tons. In this way, when driving 150,000 kilometers per year, each trailer can save 5,175 liters of fuel and reduce carbon dioxide emissions by 12.93 tons per year.
"On the surface, lightweight trailers appear to be involved in a small number of industries and vehicles, but the actual effect is very significant." Li Defeng said that for a long time, load-carrying trailers have been a major fuel consumer in the transportation field. According to statistics, there are currently about 3 million load-carrying trailers (van trailers, medium and heavy truck trailers, and flatbed trailers) in China. Although they do not account for a high proportion of the total number of vehicles, their fuel consumption accounts for 1% of the total vehicle consumption. More than 25%.
Li Defeng, deputy director of the Light Metal Department of the China Nonferrous Metals Industry Association, said that the association has been focusing on expanding the application of aluminum in the transportation industry in recent years, is committed to promoting the industrialization of high-efficiency and energy-saving aluminum trailers, and uses various channels to promote aluminum Trailers, encourage core enterprises to increase R&D investment and market trials, and identify aluminum trailers as a breakthrough in lightweight vehicles. This is an inevitable trend in the development of load-carrying trailers in the future and an important way to achieve energy conservation and emission reduction in the automotive field.
In recent years, the rise of e-commerce has opened up an unprecedented broad space for e-commerce logistics. Today's e-commerce logistics mainly transports small and light consumer goods, so there is a greater need for aluminum trailers with beautiful appearance and good waterproof sealing properties. This brings a rare development opportunity to the promotion and application of aluminum trailers.
But at present, my country's aluminum trailers have just started, and the market volume is very small. If my country's aluminum trailers reach the 70% penetration rate of developed countries, conservative estimates will save 7.66 million tons of fuel consumption and reduce carbon dioxide emissions by 22 million tons each year. At the same time, aluminum is also an energy-saving and environmentally friendly material with a recyclability rate of more than 90%. The recycling price is five times that of steel, which invisibly brings direct benefits to users.
In general, the advantages of aluminum trailers in energy saving and emission reduction, improving transportation efficiency, and reducing logistics costs are self-evident.
The "Medium and Long-term Plan for the Development of the Logistics Industry" passed on June 11 proposes to basically establish a modern logistics service system by 2020, improve the standardization, informatization, intelligence, and intensification level of the logistics industry, and improve the overall operating efficiency and effectiveness of the economy. In recent years, the "Logistics Industry Adjustment and Revitalization Plan" and the "Twelfth Five-Year Plan for Transportation Development" issued by our country also require the development of green transportation, accelerating energy conservation and emission reduction, and upgrading vehicle equipment. These provide a better policy environment for promoting lightweight vehicles, especially lightweight trailers.
It is worth noting that due to the objective existence of problems such as large production investment, high vehicle prices, and the need to strengthen the management of the transportation industry, aluminum trailers are currently encountering difficulties in expanding market applications. The inability to produce large-scale production means that the price cannot be reduced. Production costs make it difficult to expand the market. In response to this contradiction, Li Defeng suggested that the industrialization and demonstration application of high-efficiency and energy-saving aluminum trailers be listed as a major project and special financial support be provided; preferential policies such as interest discounts and tax exemptions should be introduced to encourage users to purchase and use aluminum trailers; research and development of more Strict vehicle average fuel efficiency standards and environmental recycling laws and regulations create a good environment for the large-scale promotion and application of high-efficiency and energy-saving aluminum trailers.
