China Construction Machinery Information

Guide: the super large tonnage crawler crane zcc3200np independently developed and manufactured by Zoomlion was successfully rolled off the production line on May 28. The crane was specially developed for the construction and hoisting of cap1400 in China's third-generation nuclear power plant, with a maximum lifting capacity of 3200 tons, The maximum lifting torque reaches 82000 ton meters, which is the world's largest lifting capacity

the super large tonnage crawler crane zcc3200np, independently developed and manufactured by Zoomlion, was successfully rolled off the production line on May 28. The crane is specially developed for the construction and hoisting of cap1400 in China's third-generation nuclear power plant. Its maximum lifting capacity reaches 3200 tons and the maximum lifting torque reaches 82000 ton meters. It is the mobile crane with the strongest lifting capacity in the world

with the acceleration of national economic construction, developing clean and low-carbon energy has become an important strategy in the national "12th Five Year Plan", and "actively developing nuclear power" is an important strategic policy. At present, the key hoisting equipment for the third generation nuclear power construction vigorously developed is completely dependent on imports. In order to promote the localization of the key hoisting equipment for the third generation nuclear power, the national energy administration, the national nuclear power and other ministries and commissions have convened crawler crane manufacturers to hold meetings for many times to encourage the localization of super large crawler cranes, so as to completely get rid of the current situation that the construction of nuclear power plants is controlled by others

as a leading enterprise in the field of construction machinery, Zoomlion has undertaken the important task of localization of major hoisting equipment to ensure the implementation of China's energy construction strategy. With more than 40 years of experience in crane design and manufacturing, Zoomlion has accumulated rich experience in crane key technology research, large structural member design, calculation and welding processing, and has a complete crane R & D and production system with alloy's engineering resin annual capacity of more than 500million pounds. In 2004, the company successfully developed a 200t crawler crane, which was the largest product in China at that time; In 2006, the company successfully developed a 600t crawler crane, once again breaking the record of maximum tonnage; In 2009, the company successfully developed 1000t crawler crane, which was the product with the largest lifting capacity in China at that time. At present, the company has formed a full range of 50t to 3200t products. The successful offline of zcc3200np is the result of more than 40 years' technical accumulation of Zoomlion, the crystallization of the wisdom of the whole industry, another milestone in the development history of China's crawler crane industry, and marks that the technical level of China's crawler crane has risen to an unprecedented level

Zoomlion creates industry miracle crawler crane ranks first in the world

the super large tonnage crawler crane zcc3200np independently developed and manufactured by Zoomlion successfully went offline on May 28

zcc3200np is the crawler crane with the strongest lifting capacity and the most advanced technical level in the world today. The product adopts the overall scheme of parallel double arm frame + front and rear crawler cars, which breaks through the design idea of the traditional crawler crane, and makes a breakthrough in the overall stability and anti rollover capacity of the crane, with significantly improved safety performance; In order to ensure the convenience of disassembly and transportation, the modular design method is adopted for the crane structure; In order to realize the smooth assembly of the whole machine, the manufacturing accuracy and assembly process sequence of each gear of parts are fully considered in the design, and the assembly simulation of the whole vehicle is carried out by using the three-dimensional animation simulation technology. Taking the typical frame structure as an example, in order to ensure the smooth assembly of five large box structures with multiple statics, the project team creatively proposed the "three benchmark design method for the assembly of super large frame modules", which ensured the smooth assembly of large multiple statics. In addition, the project team gathered the wisdom of the masses and made concerted efforts to complete the research on several sub courses, such as research on intelligent control of front and rear vehicles, research on three-dimensional animation simulation of hoisting conditions, analysis method of overall stability of large truss arm, dynamic analysis of boom anti roll system, etc. The product has more than 20 patented technologies, including many invention patents such as crawler crane and its boom, parallel closed control system, multi engine power unit, etc

prior to this, foreign enterprises built a solid intellectual property barrier in the field of super large tonnage crawler cranes, forming a comprehensive technical blockade. Zoomlion, as a leading enterprise in the construction machinery industry, relies on its strong R & D strength and first-class manufacturing level. In order to ensure the smooth implementation of the zcc3200np crawler crane project, Zoomlion's zcc3200np project development brings together top experts from the company's two national research institutions to form a special research group of more than 100 people, including R & D, manufacturing and management personnel A series of independent innovations have been made in project organization and R & D means, and major breakthroughs have been made in key technologies of "machinery, structure, calculation, hydraulic, electrical" and other disciplines

since 2008, we have carried out a large number of Market Research on AP1000 and actively listened to the opinions and suggestions of experts from the construction unit; From 2009 to 2010, many batches visited the nuclear power construction site to understand the advantages and disadvantages of the existing equipment and the on-site use, and consulted and exchanged with nuclear power construction experts on the hoisting characteristics of nuclear power construction. From December 2009 to March 2010, three large-scale scheme review meetings were organized to widely listen to the opinions of all parties, and many internal discussions were held to continuously improve the technical scheme; In April2010, experts from the national nuclear power department, machinery industry and nuclear power construction units were invited in Beijing to introduce the technical scheme and exchange low noise. The project scheme was highly praised by the participating experts; In 2011, it reported the project progress to the relevant national ministries and commissions for many times, and repeatedly modified the parameters and improved the scheme according to the actual needs, so that Zoomlion, together with Zhejiang Haizheng and other polylactic acid production enterprises, planned to provide ecoflex ○ R and polylactic acid heavy industry zcc3200n with spectral analysis time p products to biodegradable product enterprises, which became the key hoisting equipment most suitable for the construction of the third generation nuclear power in China

the successful offline of Zoomlion zcc3200np has once again set a new record for the maximum lifting capacity of domestic crawler cranes, making Zoomlion stand at the forefront of the International Crane Industry and breaking the monopoly of foreign countries on 3000t crawler cranes. It is of great and far-reaching significance to the realization of the strategy of vigorously developing the high-end equipment manufacturing industry in the 12th Five Year Plan, the development of the domestic construction machinery industry and the promotion of its international status
