In recent years, from the state to the local government, from capital input to policy support, the efforts to promote the construction of green mines is not small. Data show that more than 100 billion yuan has been spent on improving the geological environment of mines, and a total of 920,000 hectares of land has been restored. In 2020, all localities will continue to make vigorous efforts to promote the construction of green mines and upgrade existing open-pit mines. Protecting the ecological environment of mines and preventing and controlling dust pollution are not only the hard demand of the market, but also the general trend of mines entering a new mode of sustainable development.
At the same time, the national development and reform commission launched a six-month campaign. Dredge governance investment congestion ” Special operations. January 2020, “ Batch in advance & throughout; The completion progress of special debt was 71%, up sharply from January last year, and 90% of the special debt was invested in infrastructure. In the context of frequent policy combination, infrastructure investment growth in 2020 is expected to usher in repair. This means that the demand for sand and gravel aggregate increases linearly, and the mining intensity and scale are increasing day by day.
How to give consideration to the demand of mining efficiency and environmental protection has put forward a new test to the construction machinery industry. Doosan new products “ Throughout the three musketeers &; & ndash; & ndash; Dx360lc-9c, dx450lc-9c, and dx490lc-9c are all sincere efforts to fully consider the current industry and user needs and explore market segments under such opportunities and challenges. According to the introduction, the three products are not only the continuation of doosan 9C products. High efficiency, energy saving, environmental protection ” In particular, in view of the current situation that the blasting technology of quarry mines in China is greatly restricted, and the crushing operation of Excavator has become a rigid demand, we have enriched the options of 9C series in loading, crushing and other aspects, so as to provide customers with more environmentally friendly and efficient equipment products and solutions.
Doosan dx450lc-9c Excavator positioning “ Broken king ” Is doosan in-depth market, targeted to launch the crushing products. The equipment is equipped with doosan original crushing pipeline, electric control pedal, self-bringing oil filter element, hydraulic pressure and flow can easily control the 195 type Crusher, to ensure long-term stable operation to achieve the purpose of energy saving and fuel saving
Dx450lc-9c set the optimal length ratio of 2.6m for the forearm and 6.7m for the big arm according to the crushing characteristics, and carried 2.4 m³. Large capacity, so that it can ensure the excellent crushing capacity at the same time, the rapid and efficient completion of loading. The standard two-tooth mine track ensures that the dx450lc-9c has higher wear resistance and stronger grip in mine operations. The oil-bath air filter can effectively isolate the dust in mining and improve the service life of the equipment.
On the other new doosan dx490lc-9c Excavator, doosan's thinking and design for the large-scale mining trend in China are more obvious. Large mines have high requirements for equipment durability and efficiency. The doosan dx490lc-9c excavator, as the new strength representative of doosan 50-ton equipment, is equipped with double-rotating mada, strong rotary power and excellent maneuverability. Even in the non-blasting mining environment, the excavation efficiency remains unchanged. Cooperate with 2.72 m&sup 3; Large capacity, dx490lc-9c full 35m³ Harvesters only need 13 cycles. The whole car adopts doosan unique fuel economy advanced technology “ SP C (smart power control) ” , can perceive the work intensity in real time, output the optimal power at any time, not only for customers to reduce costs, create greater value, more energy saving and emission reduction, help environmental protection.
The dx360lc-9c is a standard 36-ton equipment with the same rotary speed and digging power as the dx380lc-9c. Equipped with the top scania engine, strong oil resistance and durable power output; KAYABA main control valve with high efficiency and large capacity, quick hydraulic response, good handling and small energy loss; Equipped with extended track, the operation stability is further improved, and the driving experience is more stable and comfortable. 6.5m big arm and 3.2m small arm, with a long working radius of 11m; 1.71 m&sup 3; Dx360lc-9c is widely used in mines, large earthwork and other projects. It is well deserved that dx360lc-9c can improve the single cycle loading capacity and ensure efficient operation. All star products ” .
Doosan construction machinery r & d department director said: “ Doosan should adopt a more environmentally friendly way, driven by scientific and technological innovation, control and reduce energy consumption, improve mining efficiency, help mining enterprises to transform and upgrade, and build a green mining industry ecological chain with government, industry, enterprises and other social forces. Throughout the &;
It is revealed that doosan three new products once launched to cause great concern in the market. The industry believes that doosan has been deeply engaged in the Chinese market channels and brand advantages for many years, attaches great importance to China's policy trends and the development of the construction machinery industry, and 9C series excavator products from research, design to production, are oriented to the actual needs of users, which is also the fundamental reason for doosan's continuous success in the market reputation.
