Mine legend! Xugong XE490HB energy-saving excavator shines!

On November 16, 2019, in China's largest grassland pastoral area, Mongolia, the XE490HB hybrid hydraulic excavator, which is mainly energy-efficient and low-fuel consumption, appeared in the large-tonnage product promotion conference of Xugong excavator. Between the blue sky and the blue sky, the XE490HB is wearing a yellow armor, but it stands out and stands out.

Innovation-driven, "energy-saving pioneer" creates a new era of mine construction

In recent years, China's mining industry has continued to promote transformation and upgrading. Heavy and rigorous working conditions have put forward higher requirements for “green environmental protection, energy saving and high efficiency” of construction equipment. Green mining and mechanization of mining have become a trend.

In this context, the Chinese excavator benchmarking company - Xugong excavator, deep focus on the new needs of the transformation and upgrading of the mining industry, continue to promote innovation drive, and aim to be one of the internationally recognized best solutions for energy saving and emission reduction - hybrid Above the technology.

In fact, before Xugong digs the machine, many manufacturers have tried the hybrid hydraulic excavator, but it is rare to finally get the model that is popular and popular. The reasons, the harsh working environment, large load changes, strong work cycle, high requirements for the coordination of actuators, etc., determine that the hybrid technology of the excavator is far more difficult than other industrial vehicles, and can not be simply transplanted in hydraulic excavation. on board.

How to develop hybrid power for engineering machinery is the core and key of the whole project, and it is also the biggest difficulty. In order to solve this problem and improve the energy-saving and emission-reducing effect of hydraulic excavators, in 2014, XCMG combined with the State Key Laboratory of Fluid Power and Electromechanical Systems of Zhejiang University and Jiangsu Xuzhou Engineering Machinery Research Institute jointly launched the “Energy Recovery Based on Excavators”. The project of research and application of hydraulic hybrid energy-saving technology. After five years, it finally developed and manufactured the XE490HB, a hybrid fuel-powered hydraulic excavator with high fuel economy, low cost and modularity.

In addition to the strong power, high efficiency and intelligent features of XCMG, the XE490HB hybrid system can also reduce the energy consumption of the engine by collecting the potential energy generated by the lowering of the boom cylinder to achieve fuel saving. At the same time, the original dual-system automatic switching technology realizes the automatic switching between the energy recovery and reuse system and the original working system, ensuring that the recovery energy can be utilized in real time and efficiently under various working conditions. With the support of a number of unique technologies, the XE490HB hybrid excavator can save about 7L per hour, saving hundreds of thousands of dollars a year!

XE490HB hybrid hydraulic excavator has more than 10 invention patents. Its successful development marks that Xugong excavator has launched a comprehensive series of super-energy mine heavy-duty excavators after successfully solving the series of problems in heavy-duty construction. charge.

Customer trust, the preferred brand of large tonnage excavator

From January to October 2019, Xugong achieved a new breakthrough in domestic sales and market share of over 40 tons of digging products, a substantial increase of nearly 70% year-on-year, of which 49 tons of fist products ranked first in the industry. Behind the eye-catching data, Xugong excavator always focuses on the needs of users, meets the expectations of users with more reliability, higher efficiency, lower cost of use and more energy saving and environmental protection. It insists on high-end products, high added value and high reliability. Responsibility, promote technology upgrades and industrial progress in China's 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 Xugong 49-ton excavators are under construction, with golden arms waving, large pieces of coal seams peeling off instantly, powerful digging forces and super high efficiency. The group of steel warriors is known as the “king of heavy load”; in Nanchang, Jiangxi, 50 XCMG XE490 excavators have once again entered the key construction project in Jiangxi to assist in the construction of infrastructure in Jiangxi. “Xugong XE490 is in work efficiency, digging power, operational fluency, etc. The aspect is comparable to foreign brands, but it is faster in terms of maintenance. Based on these, we most recognize Xugong.” Liu Chang, the person in charge of Nanchang Project, revealed that... In addition, in Guangxi, Guizhou, Heilongjiang and other places. There has also been a surge in the demand for XCMG's tonnage excavators.

The trust of the customer stems from the excellent product performance of XCMG excavator, and the Xu workers who are “one rib” are sticking to the main business. From 2008 to the present, the competition in China's excavator industry has become increasingly fierce. However, regardless of the changing geometry, XCMG has always worked hard, solid and innovative, adhered to the right path and constantly broke through, and demonstrated its true strength with “hard core” products. . From the DK series of mine heavy-duty excavators to the HB series of ultra-energy-saving mine heavy-duty excavators, the “mineral legend” belonging to Xugong excavator is gradually being opened.
