“Energy Saving and Emission Reduction” Policy At present, oil tigers have also had to fight for energy conservation under the dual test of capital and technology.

First, Sany Heavy Industries pioneered the technology and pioneered the introduction of hybrid excavators, followed by Volvo-Shandong Lingong's energy-saving loader that exceeded 10,000 units. In the increasingly competitive field of construction machinery, energy conservation has become a new key word.

While the energy-saving technology standards and policy subsidies for construction machinery are still not on the agenda, many companies have already discovered market opportunities. In the country's energy-saving emission reduction targets, energy-saving products are increasingly popular. However, Hou Yuxuan, a researcher in the investment advisory industry environmental protection industry, pointed out that the capital and technical bottlenecks are two major tests for the construction machinery to achieve further energy conservation results.

Reverse elimination For most companies, energy conservation and emission reduction are still the policy directives that must be exercised, but for Liu Yongguang, this is a simple equation.

Liu Yongguang, who has contracted several coal mines in Inner Mongolia, has three loaders in his hand. According to him, energy-saving models are about 2,000 yuan more expensive than traditional models, but with the current energy-saving effect, each unit can save 30,000 yuan per year through fuel saving. "The first one was bought in May and it works well. It is also ready to enter two more."

This market reaction also supported Shandong Lingong's energy-efficient loader, which allowed it to produce over 10,000 units in less than a year. There is no policy subsidy, there is no government to push, compared to even the civilian car market, which has benefited from sales policies, and the sales of energy-saving construction machinery have made Shandong Lingong’s chairman Wang Zhizhong say that “this performance has exceeded even before The estimate."

The market has its own abacus. For example, at the end of 2009, the social possession of construction machinery products in China exceeded 3 million units, and 3 million units of construction machinery were used annually for the cost of oil, even higher than the current year's construction machinery. The total output value, if it can improve the fuel-saving rate of the product, will greatly reduce the waste of resources.” Hou Yuxuan believes that in the case of high resource prices, the energy saving of construction machinery to meet market demand.

The energy saving space brought by the amazing energy consumption of construction machinery in the past has become even greater. "Simply speaking, through the installation of start-stop devices or energy recovery devices, we can achieve a very good energy-saving effect." Changsha Yongkang said that this is also an advantage of energy-saving engineering machinery can be Under the premise of ensuring cost, relative improvement of fuel economy performance is made.

Can not be rushed "Compared with international competitors, the gap between China's corporate energy-saving technology is still very large." Sha Yongkang said that now is only doing some simple energy-saving transformation, but high-end technology does not grasp.

It is understood that the current energy-saving environmental protection type construction machinery, some parts of the reasonable match to reduce energy consumption, some of the conversion of fuel, using natural gas to replace diesel fuel supply, while others use a hybrid power system for diesel-electric hybrid try.

An industry source also pointed out that the application of new energy technologies in construction machinery is more feasible than that of automobiles because the former is operated in a relatively fixed place, so that charging and solar energy utilization can be relatively stable. .

Li Liangang, Minister of Strategic Planning of Shandong Lingong also stated that “in the existing temporary engineering technology line, the energy saving limit that can be estimated is only 25%. If the next energy saving target is still needed, it needs to be converted to hybrid power, but The economic and reliability of the latter have brought great challenges to industrialization."

This is also the reason why the country has not made mandatory energy-saving requirements for such products. Li Xinnan, inspector of the Department of Policy and Regulation of the Ministry of Science and Technology of the People's Republic of China, said that in the end what kind of technology is used to carry out energy conservation is an issue in development. Who will set the standard? It is not the government but the competition in the market that requires more participation from the company.

At the same time, "because there is no uniform national standard for the fuel consumption test of such products, it is unlikely that there will be an energy-saving allowance like a car in the short term." Li Lian-gang analyzed that "contrast to other consumer products such as automobiles, if construction machinery is truly To achieve energy savings, the market is bound to have, for the production companies, product profits are enough to make up for R & D investment."

“It is an ideal way to dominate the development of technology products by the market rather than the government. However, due to the complexity of the construction machinery industry itself and the limitations of its energy-saving technologies, the potential for energy-saving development in the industry must continue to receive attention. "People from China Merchants Bank said.
