Continuous innovation of engineering machinery technology innovation

Judging from the list of “China's annual TOP50 (2013) for construction machinery products” promulgated recently, in 2012, a number of technological developments in the Chinese construction machinery industry achieved substantive progress: more accurate product positioning, large-scale, high-tech content, and personalized products. In the corresponding construction field, it has been popularized and applied. At the same time, the continuous upgrading and extensive application of energy-saving product technologies has enabled construction machinery products to participate in the construction of a “two-type” society with a continuous increase in depth and breadth.

Social and economic benefits highlighted

The technological innovation of construction machinery has become the driving force behind the transformation and upgrading of industries and the improvement of the utilization of social resources. The effective transformation of technological innovations has facilitated the rapid transformation of construction technology and produced good social and economic benefits. This contribution is increasing year by year. situation. The QAY1200 all-terrain crane of Xuzhou Heavy Machinery Co., Ltd. and the ZLJ5530THBK63X-6RZ boom type concrete pump truck of Zoomlion Heavy Industries and Machinery Co., Ltd. which were awarded the highest award for the “China Construction Machinery Annual Product TOP50” award are all continuing. On the basis of innovation, constantly surpass the crystallization of self.

The QAY1200 all-terrain crane relied on Xugong’s accumulation of technology, control technology and boom technology for all-terrain vehicles over the years, overcoming the self-removing technology of the oversized tonnage crane boom, the overweight crane’s counterweight, and the deformation of the large-span X-leg. Compensation and many other technical problems. Located in 2.5MW and below wind power, petrochemical, power plant construction and other engineering needs. The first product was successfully applied to the construction of 2.0MW wind power in Fujian, and the second product has been offline and successfully signed. It indicates that the research and development technology of China's 1,000-ton all-terrain crane has become more mature.

The ZLJ5530THBK63X-6RZ boom type concrete pump truck is the longest 5-bridge pump truck with global steel booms. It is a perfect combination of the new X-type outrigger technology and advanced structural lightweight technology that enables easy access to narrow sites. After optimizing the angle and length of the 6-arm, the blind area of ​​the cloth is effectively reduced. Compared to the conventional 5-arm 62m pump truck, the actual cloth height is increased by 27.9% and the cloth range is increased by 20%. After the launch of the aircraft, it has become a new benchmark for the industry. Under its leadership, Zoomlion’s market share of pump trucks with 60m and above in 2012 exceeded 60%.

According to experts from the industry, the successful application of these two products in large-scale projects has led to a steady upgrade of the entire industry's product technology, and it has also become a strategic product for enterprises to seize the commanding heights of technology, achieving a successful transition from input to revenue.

In addition, the D1250-80 tower crane manufactured by Zoomlion Co., Ltd. solves the design problem of the long boom's bearing capacity, stability, and lightweight contradiction. It is the world's first boom length exceeding 100m. Tower cranes meet the needs of major theaters, pavilions, water conservancy and hydropower projects. The equipment is currently in service at the Xiamen International Center project.

More accurate product positioning

In 2012, the growth rate of the construction machinery industry slowed down, and many construction machinery products were struggling in a highly homogenized competitive environment. At the same time, some products that focus on market segmentation and precise positioning have come out of the independent market.

Shaanxi Tongli Heavy Industry Co., Ltd. TL855 non-road wide body dump truck adopts the vehicle ground mechanics physical model design to overcome the adaptability of transportation equipment on non-highway roads and the reliability problems of driving system components. Since its launch on the market, the machine has sold more than 1,000 units, of which 688 units were sold in 2012, making it the fastest-growing market for 50t class non-road widebody dump trucks with the highest market share.

Cass Engineering Machinery (Shanghai) Co., Ltd. WX210 multi-function wheeled excavator, based on an in-depth understanding of the needs of customers in ports, municipalities, roads, materials processing and other industries, puts forward that chassis frame and drive can be customized according to customer needs. Axes, operating handles and force settings, appearance style. After being put on the market, it was well received by users. The XS302 type hydraulic single drum vibratory roller of XCMG Road Machinery Division was specially developed for large-scale projects and solved the problems of traditional compaction equipment such as hydropower dams and large-scale open-pit mines. Poor adaptability to real operating conditions. Once this product came out, it was successfully applied in Yunnan hydropower dam, Qinghai large-scale open-pit coal mine and other projects.

In addition, the ZX130H harvester from Hitachi Construction Machinery (Shanghai) Co., Ltd. was born for the operation of forest farms, which effectively promoted the mechanization of woodland operations, greatly improved the operating efficiency, and reduced the intensity of manual operations. The YC13-8 crawler hydraulic excavator from Guangxi Yuchai Heavy Industry Co., Ltd. is favored by the market for micro-engineering, rural engineering, and replacement of labor.

Unique technology genes

The core technology that adapts to the market demand is an important embodiment of the comprehensive competitiveness of the enterprise, and it is also the fundamental for the company to control the market and continue to develop. In 2012, in the transition from market-driven to technology-driven transformation of the construction machinery industry, the company has built its own core competitiveness through continuous independent innovation, and unique technology genes are being formed.

The SD90-5 bulldozer of Shantui Construction Machinery Co., Ltd., which won the TOP50 technological innovation gold medal, is the domestically-made maximum power bulldozer and has been achieved in terms of complete machine matching, thermal management system, modular design, intelligent control, and high-power engineering machinery manufacturing. A number of technological breakthroughs have led to the development of China's bulldozer industry in the direction of high reliability, high-tech content, and large tonnage, highlighting Shantui Construction Machinery Co., Ltd.'s unique core competitiveness in bulldozer technology.

Continually committed to the development of environmentally friendly energy-saving products, Shandong Lingong Construction Machinery Co., Ltd. adopts the second-generation energy-saving technology of the LG955N energy-saving wheel loader, once it was launched will be recognized by the market, and effectively stimulated the sales of the entire line of products, energy saving Has become Shandong Lingong's unique technical gene.
