On the opening day of the first session of the 14th National People’s Congress, during the deliberation of the Jiangsu delegation, National People’s Congress representative and chief engineer and vice president of XCMG, Shan Zenghai, sat directly opposite General Secretary Xi Jinping. As soon as he opened his mouth, the General Secretary recognized him.
More than five years ago, when the General Secretary investigated in Xuzhou, Jiangsu, the first stop was XCMG, leaving a deep impression on XCMG.
After listening to the new report card of XCMG reported by Representative Shan Zenghai, General Secretary Xi Jinping lamented: “China’s manufacturing industry categories are very complete. What we need to strive for now is a comprehensive improvement. The previous medium and low end should move upward and layout the high end. High-quality development should be reflected here. At any time, China cannot lack the manufacturing industry.”
Layout of “national heavy equipment”, breaking through the “bottleneck” problem, constantly planning, accumulating and gathering momentum for shaping the new pattern of economic development, which is exactly the true portrayal of XCMG in recent years.
“The Global No. 1 Crane” national heavy equipment polishes China’s manufacturing business card.
Recently, on the 100,000-kilowatt wind power project supporting the comprehensive energy service project in the ecological town of Chagan Lake in Songyuan City, Jilin Province, the newly promoted “Global No. 1 Crane” XCMG 2600-ton-class crane last year extended the golden steel giant arm into the air to complete the hoisting of the wind turbine with a capacity of 6.25 MW, a height of 126 meters and a weight of 127 tons, perfectly staging the first show in Northeast China!
Nowadays, as one of the dominant industries in domestic carbon peaking and carbon neutralization, the wind power equipment manufacturing is developing in the direction of “higher, heavier and larger”, and the lifting equipment with larger lifting weight, higher lifting height, more efficient heavy-duty transfer and more secure technical guarantee has become the necessary guarantee for the rapid development of China’s wind power industry.
Looking at the thriving wind power industry in recent years, the height and weight of the wind turbine hoisting have been continuously increased. Insights into this market demand and potential, the 2600-ton super crane that has made great efforts in the wind power field has also emerged under this background.
As the first equipment with a 10-axis chassis in the world, the body of the XCA2600 is 500 mm lower than that of similar products in the market, and the minimum ground clearance is 200 mm higher than that. The ultimate manifestation of “one high and one low” is the display of XCMG’s accelerated independent innovation achievements. In the application field, it guarantees the running of the vehicle in the wind power field to the greatest extent. It can not only compete with the “coarse gravel”, but also contend with the “gully and ditch”, and has the strongest performance through the ground.
“The Global No. 1 Crane” chief designer Li Changqing said:
“The 2600-ton all-terrain crane can complete the extreme working condition of 160 meters in height and 173 tons in lifting weight, and can cover more than 90% of the onshore wind turbines in various provinces and cities in China, increasing the efficiency of super-large onshore wind turbine installation by 30% – 50%, and continuously outputting the strength of national heavy equipment for the realization of the wind power installed target during the 14th Five-Year Plan period.”
China’s voice leads the new trend of explosive thousand-ton-level new wind.
The demands from the front end of the market drive the technological innovation of China’s super-large crane industry to accelerate rapidly. Especially since the General Secretary observed XCMG in December 2017, XCMG hoisting machinery has followed the earnest exhortation of “striving to occupy the international commanding heights and grasping the right to speak in technology”, and the “market and R & D teams have both moved forward” to spend a lot of time accurately connecting with user needs; Every year, hundreds of millions of yuan are spent on the R & D and technical transformation expenses of super cranes; In the exploration of “higher, larger and faster”, continue to increase the “safety” weight.
Having been in the crane field for a long time, XCMG has always been good at creating explosive models, and now this tradition has been continued to the “super-large tonnage” product pedigree. Since the appearance of the thousand-ton-level crane, XCMG has been firmly in the “king” position in this field, and the market sales are far ahead.
With the introduction of the 2600-ton crane, the “Matthew effect” of XCMG’s leading position in the super-large equipment field is further highlighted. The “dual-king bombs” of the 2600 “listed as explosive products” have become the “new favorite” in domestic and foreign markets, contributing to the country’s green and low-carbon development and leading the trend of wind power construction of super-large equipment.
Behind the report card with quite high gold content is the self-reliance and self-improvement scientific and technological innovation system created by XCMG and the user reputation of “buying with confidence and using with peace of mind”. The most widely spread example is that in the development process of the crane, the test of the boom strength alone has exceeded hundreds of thousands of times, which is quite harsh in the global range.
From 1200 tons, 1600 tons, to 2000 tons, 2600 tons, XCMG makes the record of “The World’s First Crane” constantly refreshed, and XCMG’s “Super Mobile Crane” innovation project once won the highest award in the industrial field in China – the China Industry Award.
Nowadays, “XCMG Gold” continuously projects a dazzling brilliance in domestic and overseas markets, becoming the representative of China’s equipment manufacturing industry moving towards high-end. In the global crane field, starting from the thousand-ton-level crane, XCMG shouts out “China’s voice” in core technologies such as high-altitude performance, heavy-duty transfer, safety control and precise control, and leads the innovation trend.
Key technologies of independent innovation enhance the confidence of China’s manufacturing.
Xi Jinping emphasized when participating in the deliberation of the Jiangsu delegation of the 14th National People’s Congress that accelerating the realization of high-level scientific and technological self-reliance and self-improvement is the only way to promote high-quality development.
The intense demand of “firmly grasping the crucial skills in our own hands” drives the rapid acceleration of technological innovation speed of XCMG. Especially since General Secretary Xi Jinping inspected XCMG in December 2017, XCMG has followed the earnest exhortation of “striving to occupy the international commanding heights and grasping the right to speak in technology”. The marketing and R & D teams have both moved forward, spending a lot of time accurately connecting with user needs. Every year, hundreds of millions of yuan are invested in the R & D and technological transformation expenses of super cranes, and continuously increase the “independent innovation” weight in the exploration of “higher, bigger and faster”.
XCMG hoisting machinery takes the lead in establishing a brand-new G-generation technology platform of “science and technology intelligence, green energy conservation, quality efficiency, and ultra-high performance”, breaking through key technologies such as intelligence, energy conservation technology, humanization, and lightweight one by one, promoting industrial progress with original technologies. On this basis, the 8-2600 ton series of products developed have all reached the international advanced level, continuously leading the industrial development, and have won the highest honor in the field in China – the China Gold Award twice.
At present, XCMG hoisting machinery has 531 invention authorizations, and 44 overseas authorizations in the United States, Australia, Europe and other countries and regions, and the technology implementation utilization rate is more than 95%. Among them, the key technologies such as the double-cylinder head single-cylinder plug-in telescopic boom, the wind power combined boom, the variable super-lift, and the large-load independent suspension are all pioneered by XCMG.
The introduction of the “Overall Layout Plan for the Construction of Digital China” has injected a “cardiotonic” into the industrial digitization. In recent years, XCMG Heavy has firmly grasped the opportunity of the new round of scientific and technological revolution and industrial transformation, and the intelligent transformation and digital transformation have made steady progress.
By using information technologies such as the Internet of Things, cloud computing, big data, and the industrial Internet to integrate with manufacturing technology, XCMG hoisting machinery has built the industry’s first 5G smart industrial park and 5G full value chain smart factory, creating 44 typical application scenarios in 15 business links, establishing 4 smart workshops composed of 10 intelligent production lines, with a 100% numerical control rate of key equipment, a 53% increase in equipment comprehensive utilization rate, a 32.6% reduction in R & D cycle, a 39.1% increase in production efficiency, and a 21.4% reduction in operating costs, and the overall quality level has reached 4σ.
It has been successively rated as the national intelligent manufacturing benchmark, the national-level intelligent manufacturing demonstration factory, and the national pilot demonstration of the integration and development of the manufacturing industry and the Internet, and is the first enterprise in the industry whose intelligent manufacturing capability maturity assessment has reached the level 4.
In the production area of XCMG hoisting machinery, through the empowerment of 5G technology and the application of big data, the “Internet of Everything” can be achieved. Equipment, product vehicles, logistics vehicles, various materials in the production link, the current inventory situation… all manifestations are clear at a glance, and the degree of less manpower and automation in the factory is getting higher and higher.
Just as Representative Shan Zenghai said in the representative passage of the 2023 National Two Sessions: “Super mobile cranes are considered one of the products with the highest technological content and the greatest difficulty in R & D in construction machinery. Our team of more than 200 experts and more than 100 senior technicians, after ten years of hard work, have overcome 7 key core technologies and completely formed the ability of independent R & D of thousand-ton-level cranes.”
There is no doubt that in the global field of cranes, XCMG has already grown from a runner-up to a leader. Facing the future, XCMG Heavy, which has great first-mover advantages and confidence, has set a clear goal for itself: Keep in mind the exhortation, be grateful and strive forward, be bold to闯敢干善作善为, accelerate scientific and technological self-reliance and self-improvement, and strive to climb the global industrial Everest, and promote Chinese-style modernization with the high-quality development of the manufacturing industry!
