On November 16, 2019, in Mongolia, China's largest grassland pastoral area, the XE490HB hybrid hydraulic excavator, which focuses on high energy efficiency and low fuel consumption, appeared at the XCMG excavator large-tonnage product promotion conference. Between green grass and blue sky, XE490HB is wearing yellow armor, standing tall and magnificent.




Driven by innovation, "energy pioneer" creates a new era of mine construction


In recent years, China's mining industry has continued to promote transformation and upgrading. Heavy and severe working conditions have set higher requirements for "green environmental protection, energy saving and high efficiency" of construction equipment. Greening and mechanization of mining have become a trend.


Against this background, the benchmarking company of China's excavator, XCMG Excavator, focuses on the new needs of the transformation and upgrading of the mining industry, continues to promote innovation-driven, and targets the internationally recognized best solution for energy saving and emission reduction-hybrid Above technology.




In fact, before the XCMG excavator was settled, many manufacturers have tried hybrid hydraulic excavators, but it is rare for models to finally be available on the market and welcomed by users. The reason is that the harsh working environment, large load changes, strong working cycles, and high requirements for the coordination of actuators determine that the hybrid technology of excavators is much more difficult than vehicles in other industries, and it cannot be simply transplanted in hydraulic excavations. on board.




How to develop a hybrid power for engineering machinery is the core and key of the whole subject, and it is also the most difficult point. In order to solve this problem and improve the energy-saving and emission-reduction effect of hydraulic excavators, in 2014, XCMG excavators joined the State Key Laboratory of Fluid Power and Electromechanical Systems of Zhejiang University and the Jiangsu Xuzhou Engineering Machinery Research Institute to jointly launch the "Excavator-based Energy Recovery Research and Application of Energy-Saving Technology for Hydraulic Hybrid Power ". It took 5 years to finally develop and manufacture the market-oriented high-fuel-saving, low-cost, modular hybrid hydraulic excavator XE490HB.




In addition to the strong power, high efficiency and intelligence of XCMG excavators, the hybrid system of XE490HB can also reduce the energy consumption of the engine by collecting the potential energy generated by the lowering of the boom cylinder to achieve the purpose of saving fuel. At the same time, the original dual-system automatic switching technology realizes automatic switching between the energy recovery and reuse system and the original working system, ensuring that all kinds of working conditions can use the recovered energy in real time and efficiently. With the support of many unique technologies, the XE490HB hybrid excavator can save about 7L of fuel per hour, easily saving more than 100,000 a year!


XE490HB hybrid hydraulic excavator has more than 10 invention patents. Its successful research and development indicates that after Xugong excavator successfully solved a series of difficult problems in heavy-duty construction, it launched a comprehensive approach to the field of ultra-energy-saving mining heavy-duty excavators. charge.




Customers trust, the brand of choice for large tonnage excavators


From January to October 2019, XCMG achieved new breakthroughs in domestic sales and market share of large-scale excavation products of more than 40 tons, a substantial increase of nearly 70% year-on-year. Among them, 49 tons of fist products ranked first in the industry. Behind the eye-catching data is that XCMG excavators always focus on user needs, meet users' expectations of more reliable, more efficient, lower use costs and more energy-saving and environmental protection. Adhere to high-end products, high added value, high reliability, The sense of responsibility promotes the technological upgrade and industrial progress of the Chinese excavator industry, and has been widely recognized by users.




At the site of the largest open-pit coal mine in Asia, the Harwusu Open-pit Coal Mine, dozens of XCMG 49-ton excavators are under intense construction. With the swing of golden arms, large coal seams are spalled instantly. The powerful digging force and ultra-high efficiency make this The group of iron and steel soldiers is known as the "King of Heavy Duty"; in Nanchang, Jiangxi, 50 XCMG XE490 excavators have once again settled in key construction projects in Jiangxi to help Jiangxi infrastructure construction. It is comparable to foreign brands in terms of maintenance, but it is faster in maintenance. Based on these, we recognize XCMG the best. "General Manager Liu of Nanchang revealed that ... In addition, in Guangxi, Guizhou, Heilongjiang and other places There has also been an upsurge in demand for XCMG large tonnage excavators.




The trust of customers stems from the excellent product performance of XCMG excavators, and also from the insistence of XU workers on their main business. For more than ten years since 2008, competition in the Chinese excavator industry has become increasingly fierce. However, regardless of the changing geometry, XCMG excavators have been working hard, innovating, sticking to the right path, making breakthroughs, and using "hard core" products to show their true strength . From DK series of mining heavy-duty excavators to HB series of ultra-energy-saving mining heavy-duty excavators, the "Mining World Legend" belonging to XCMG excavators is gradually opening.
