On December 26, 2021, on the birthday of the great man Chairman Mao, the sixth "Made in China Day" will come as scheduled.

Yang Yufeng, chief engineer of XCMG’s “Shenzhou No. 1 Dig” 700-ton mining excavator, participated in the “Roundtable Forum 2: Independent Innovation of Made in China” on China Manufacturing Day online, and sat on the same stage with the “most powerful brain” of national high-tech technology. Cutting-edge technology has collided with sparks made in China.

The product is offline

In April 2018, XCMG’s 700-ton hydraulic excavator officially rolled off the assembly line. One bucket can hold 60 tons of materials, which is close to the capacity of a train skin. The maximum digging height is 18.7 meters, which is equivalent to the height of a 7-story building. This equipment is powerful The power comes from two diesel engines with a power of 1700 horsepower, which is equivalent to the power of nearly 30 family cars, which is called "China's No. 1 Dig".

Yang Yufeng: “Before 2000, excavators of more than 200 tons had to be purchased from abroad. Today, China can manufacture super-large excavators from 200 to 700 tons. After completing the development of super-large-ton hydraulic excavators, 20 were used abroad. For many years, China has only used it for 7 to 8 years."

Yang Yufeng's firm and confident words convey the confidence of China's high-end equipment manufacturing. In the field of global open-pit mining equipment intelligent manufacturing, XCMG continues to overcome technical barriers and product tonnage continuously “jumps” to become the mainstream supplier of global mining equipment, helping China's mining machinery to enter the global stage.

Try to climb Mount Everest

In the 1990s, XCMG organized its employees to visit and study abroad. When asked if foreigners could take pictures, the answer was: "You can take pictures and videos. You can't learn it even if you take pictures." You won’t be able to learn it even if you take a photo.” Like a hard thorn, it deeply pierced the hearts of all XCMG technicians and became their “motivation”.

In less than ten years, Yang Yufeng and the others have not only taken off the hat of “cannot learn” large excavators, but have also become the existence of others “cannot learn”. At XCMG, every technician is full of original mission, and most of them are silent. However, in front of the technological mountains, it is the quality of "sinking down" and "sinking down" that can move the technology forward bit by bit. The "blocking the road", achieved technological leadership, and the summit of Mount Everest, making China the fourth country in the world with R&D and manufacturing capabilities for hydraulic excavators above 700 tons.

With great righteousness in mind

In 2013, XCMG's 700-ton hydraulic excavator project was officially launched. As the general manager of the project, Yang Yufeng feels a lot of pressure. "I have never seen such a large-tonnage product in kind. It is by no means as simple as magnifying the existing product by a certain multiple." At that time, what was in my mind every day was: What kind of material? How is the internal structure? How to arrange the layout and so on, these are all unknown at the time.

With breakthroughs in the centralized application of key core technologies for large-scale hydraulic excavators in China, XCMG successfully led the transformation and upgrading of China's mining construction equipment, and drove special steel products, the intelligent level of mining machinery, high-voltage power control technology, hydraulic systems, and AC drive systems, etc. The development of related industries.Editor/Ma Xue
