Xugong, crane coronation ceremony (3)

Technology is the DNA of Xugong, the root of Xugong, the soul of Xugong. Wang Min, chairman of Xugong Group, has repeatedly emphasized this point for decades.

Technical mad & leader

The super mobile crane that won the "China Industrial Award" was recognized by the construction machinery industry as one of the products with the highest technological content and the most difficult research and development. It is more important to become an important step for Xugong to complete the "Mount Everest".

The so hardest journey to climb the summit is the last 10% of the climb. In order to break through the last 10% of the problem of super-lifting equipment technology, XCMG has established an innovative system and mechanism of “core technology R&D and guiding technology development, scientific research and industry support each other, excellent quality and standardization management, and performance improvement”: relying on enterprises 60 years of crane industry accumulation and Xugong National Enterprise Technology Center professional R & D strength, invested 1.5 billion yuan to build ten major laboratories, established three overseas R&D centers in Germany, the United States, Brazil, and also built an area of ​​860 acres The National Comprehensive Test Site has created the “National Key Laboratory of Intelligent Manufacturing for High-end Construction Machinery”.

Xugong Crane

Among them, the “National Key Laboratory of Intelligent Manufacturing of High-end Construction Machinery” is the backbone of Xugong’s entire technical brain. Here, it not only establishes a core original technology research and experimental verification system that leads the development of the industry, but also solves the “hollowing” of product technology and industrial chain. The actual problem. Utilizing the laboratory's international vision and resources, Xugong was able to focus on engineering machinery “full life cycle design technology”, “key component intelligent manufacturing technology”, “heavy load motion intelligent control technology”, “greening and intelligent service technology”. "Four major technical directions, the application of basic research and industry-oriented basic research.

Heavenly rewards, self-satisfaction

With the systematic system of the layout and the deepening of the exploration, the research and development results of Xugong cranes have once again “concentrated outbreaks”.

First and foremost, it is a seemingly simple, but in reality, it has constrained the problem of the global crane industry for a long time - the weight of the car body, which is what is usually said to reduce the weight of the car.

In the global industry, the products are lighter in weight, but the performance is unchanged or even improved, which is the target that the giants hope to break through. Here, Xugong cranes, which dare to invest heavily, have already won.

Under the same weight, XCMG's lifting performance exceeds the highest level of 3%-10%; in wind power installation work, the easy-to-play Xugong crane has twice the efficiency of the industry's highest level; in petrochemical installation, the efficiency is the best. 5 times the level.

To do this, Xugong's secret is to create a parametric multi-body dynamics machine optimization matching technology, which fills the theoretical calculation of the nonlinear calculation and static stability calculation of the statically indeterminate boom, and effectively improves the working performance of the whole machine. At the same time, the innovative design of the telescopic combination boom technology with super-starting function makes the number of crane telescopic booms break from 5 knots to 8 knots, and the combined arm length breaks from 68 meters to 180 meters, and the lifting weight is increased from 100 tons to 2000. Ton. "In this way, the industry problem of contradiction between the performance of the whole machine and the weight of the whole machine was solved, and the rapid development of the super all-terrain crane was promoted," said Shan Zenghai, deputy general manager of the lifting machinery division of Xugong Group.

While conquering its own weight, Xugong Crane is also bold in innovation in chassis technology. “We introduced the chassis technology used in high-end commercial vehicles to the crane products. We are the first crane company to do this.” Shan Zenghai said, “Many international brands are not willing to spend large sums to improve these details, but Xugong is willing to invest here, we are not satisfied with defending the city; always hitting higher and better, is our normal state."

Xugong Crane

For large tonnage super cranes, this is definitely a “just need”. In the past, large cranes, with many axles and heavy self-recovery, severely limited the efficiency of work and the speed of transition. With the application of XCMG's original all-terrain chassis technology and integrated brake management system, the crane can carry 230 tons of weight as long as 9 axes. Not only that, but the weight reduction and the strengthening of the chassis technology allow the crane to brake at a speed of 30 km/h, and the braking distance is 15% shorter. “Safety, convenience, fuel economy, all come up all of a sudden. "The users who have used Xugong's new products are quite consistent.

These are just the "one corner" of XCMG's innovative machinery. To make leading design and technology into real products, excellent and lean production and manufacturing are essential, and Xugong is one of the best representatives of the entire equipment manufacturing industry.

Every time I upgrade, Xugong goes further to "perfect manufacturing"

In the huge and spotless manufacturing base of XCMG cranes, there are many “unique” equipments in the industry. “These equipments are designed by ourselves and are processed according to actual needs. Nowhere else can we find them.” Shi Xianxin, chief engineer of Xugong Group Xuzhou Heavy Machinery Co., Ltd. said. Similar processes and application models are everywhere in the Xugong crane manufacturing workshop. The manufacturing system that combines the system perspective with micro-innovation, as well as the perfect industrial chain, accelerates the “manufacturing capability” of the Chinese crane industry to the highest level in the world.

A set of numbers can prove this.

In Xuzhou, the new manufacturing base where Xugong Crane has just moved in, the automatic welding rate of key components reached 72%, and the numerical control processing rate reached 100%, exceeding 50% of the peers.

Xugong product line and automated logistics

The highly flexible and flexible product line adopts intelligent distribution and automated logistics, and is compatible with the production of more than 30 kinds of products, and builds the industry's most intelligent super crane production system.

Entering different production lines, distributed in the intelligent online detection system and linearized debugging system application of each process, the product debugging cycle is shortened by 50%, and the average production cycle is shortened by 30% compared with the industry.

As the most innovative and energetic enterprise in China's construction machinery industry, Xugong is a big tool for the encouragement and cultivation of “talent”. In the super-lifting equipment technology, Xugong rated the super-innovation project and the series of products as the first prize of the group-level major innovation project three times, and awarded 10 million yuan in three major awards, attracting more than 200 Chinese and foreign technical experts. Work with more than 100 senior technicians to focus on the project.

Talent Echelon at the top of Xugong Pyramid

Continued accumulation, unremitting technical pursuits, and the talent ladder at the top of the pyramid, all of which have produced a wonderful and fierce chemical reaction in Xugong cranes – the “patent pain” that once restricted the Chinese crane industry is being dissolved. Up to now, mobile cranes have been granted 1,850 patents, including 566 invention patents. Among them, XCMG super mobile crane has reached the international leading position in the lightweight technology of super large mobile crane structure, multi-axis heavy-duty high-speed off-road chassis driving technology, high-flow crane intelligent operation technology, and super large-scale component hoisting construction method innovation technology. Level; 3 large-scale mobile crane rapid assembly and transfer technology, fully closed hydraulic control system, large-span double-track chassis cooperation technology and other three projects have reached the international advanced level.
