China's construction machinery companies are making great strides towards energy saving and emission reduction

In December 2009, at the Copenhagen conference, Premier Wen proposed that by 2020, the carbon dioxide emissions per unit of GDP will fall by 40%-45% compared with 2005, without any conditions, and it will not be linked to any country. On May 8, 2010, when Deputy Prime Minister Li Keqiang attended the Green Economy and Climate Change International Cooperation Conference held in Beijing, he proposed that the development of a green economy has become an important trend. In 2010 in China, energy conservation, emission reduction and green development received more attention. The construction machinery, as a large emitter, also made efforts in 2010 to make efforts to keep up with the national policy, and strive to achieve energy-saving emission reduction.

The current situation of energy conservation and emission reduction in China At present, China's requirements and regulations for energy saving and emission reduction are not perfect. For example, there is no standard requirement for product carbon dioxide emissions and product energy conservation.

There are many ways to implement energy conservation and emission reduction, for example, from the technical aspects of the product: improvement of power source, improvement of transmission mode, improvement of matching and control, lightweight design, and remanufacturing technology.

For construction machinery, power sources mainly refer to oil, gas, batteries, and external plug-in power supplies. Improvements in combustion performance and EFI control of internal combustion engines are also one of the effective ways to save energy and reduce emissions. The development of hybrid power is another effective way. way. At present, many companies in China have begun to study and have achieved results. At the China Machinery Industry Conference on Energy Saving, Emission Reduction and Resource Utilization held on October 19th, 2010, H23 and H25 diesel engines developed by Changchai were selected for the “Electrical Energy Saving Equipment (Products)” with their high efficiency, energy saving, and excellent emission targets. The list is the only domestic energy-saving single-cylinder diesel engine to enter the catalog.

The change of power source is mainly emission reduction, followed by energy saving, while the improvement of transmission mode, matching and control improvement is mainly energy saving. From the low transmission efficiency mode to the high transmission efficiency mode, more energy can be saved. The rational match between the engine and the transmission system, the working system and the walking system is advocated, and the precise control of the transmission is advocated. The main purpose is to increase the utilization rate of energy so as to achieve the purpose of energy saving.

Remanufacturing is characterized by resource conservation, energy conservation, and environmental protection. It focuses on the comprehensive utilization of high technology such as information technology, nanotechnology, and biotechnology, enabling the development and use of the value contained in used resources to become the highest possible value. The best way to implement energy conservation and emission reduction plans.

Xie Zhenhua, deputy director of the National Development and Reform Commission, said that the remanufacturing industry is the industrialization of high-tech repair and transformation of used products, and vigorously developing the remanufacturing industry is an important way to achieve circular economy, energy-saving emission reduction, and sustainable development.

Domestic and foreign remanufacturing contrasts with developed countries such as the United States and Japan. The remanufacturing technology of construction machinery is very mature. Remanufactured products have already formed scale and industry, and the economic benefits are obvious. However, our country's remanufacturing is still in its infancy, but even at this difficult time, which has just started, our domestic companies are also hard at work on remanufacturing, whether it is a wholly-owned venture or a joint venture.

National emphasis on energy conservation and emission reduction Energy conservation and emission reduction In the national "Eleventh Five-Year" and "Twelfth Five-Year Plan", the construction machinery sector is the key support content, and is listed in the "863" and other scientific and technological plans. In April 2010, the National Development and Reform Commission stated that it will prepare the "Remanufacturing Industry Development Plan" and "Remanufacturing Product Catalogue" and formulate corresponding regulations to speed up the cultivation of a batch of remanufacturing typical enterprises. Starting from October 1, 2010, the “Exhaust Pollutant Emission Limits and Measurement Methods for Diesel Engines Used in Non-road Mobile Machinery (Phase I, II, China)” (GB20891-2007) will be implemented by the State II. This shows the country's determination and speed to promote energy-saving and emission reduction.

The company implements energy conservation and emission reduction XCMG plans to invest RMB 3.4 billion in crane remanufacturing China's major construction machinery manufacturer Xugong Machinery announced in December 2010 that following the resolution of the company’s board of directors, the company will invest nearly RMB 3.4 billion to build two crane projects. Including the investment of 620 million yuan to implement the crane remanufacturing project, and the investment of 2.74 billion yuan to implement the all-terrain crane construction project.

The company stated that it plans to invest 620 million yuan in the implementation of the crane remanufacturing project through its holding subsidiary Xuzhou Heavy Machinery Co., Ltd., in which fixed assets investment is 470 million yuan and the project construction period is 24 months. After the project is completed, it is estimated that the new sales revenue will be 830 million yuan and the net profit will be 140 million yuan.

Wuhan Maxima: Leading Machinery Remanufacturing to Power Cycling Economy Wuhan Maxima is a group company that integrates "whole machine sales, maintenance services, spare parts supply, leasing, two mobile phone transactions, training, and remanufacturing". Since its establishment in 2002, it has been eight consecutive miles. The year ranked first in Hubei industrial machinery industry.

The leader of the Hubei construction machinery industry foresaw the great potential of remanufacturing construction machinery and its significance for low-carbon environmental protection many years ago. In April 2008, Wuhan Maxima invested 150 million yuan to build a remanufacturing plant covering nearly 100 acres. In December 2009, Wuhan Maxima was selected by the Ministry of Industry and Information Technology as the first batch of pilots for remanufacturing units of mechanical and electrical products, and was approved by the National Development and Reform Commission as a circular economy pilot project. In May 2010, the first remanufactured excavator in Wuhan Maxima successfully went offline and was successfully sold. From the construction machinery distributor to the remanufacturing of construction machinery, Wuhan Maxima achieved a magnificent turn.

China's first hybrid excavator was released on the Sanhe Intelligent Line. On August 20th, the first commercial hybrid excavator independently developed in China was successfully rolled off the first industrial park of Hunan Shanhe Intelligent Machinery Co., Ltd. “This marks a major breakthrough in the research on energy-saving and environmental protection technologies in the field of domestic construction machinery, breaking the monopoly of foreign companies in this field and an important milestone in the commercialization of hybrid excavators in the Chinese construction machinery industry. "The China Construction Machinery Industry Association excavator branch secretary Li Hongbao said.

In recent years, China's construction machinery industry has been paying more and more attention to energy conservation and emission reduction, and more and more attention has been paid to hybrid power and remanufacturing. Although there are still many imperfect places, our country has been making continuous efforts, and our construction machinery industry companies They are following the call of the national policy, committing themselves to energy conservation and emission reduction, making great strides to the advanced world level and becoming a manufacturing powerhouse.
