The ZCC3200NP, an oversized tonnage crawler crane independently researched and manufactured by Zoomlion, was successfully off the assembly line on May 28th. The crane was developed specifically for the CAP1400 construction and hoisting of China's third generation nuclear power plant. The maximum lifting capacity is 3,200 tons, and the maximum lifting torque is reached. 82,000 tons of meters is the world's most powerful mobile crane.
With the acceleration of national economic construction, the development of clean low-carbon energy has become an important strategy in the national "Twelfth Five-Year Plan", and "actively developing nuclear power" is an important strategic policy. At present, the third-generation nuclear power construction key hoisting equipment that is being vigorously developed is completely dependent on imports. In order to promote the localization of the third-generation nuclear power equipment for key hoisting, the National Energy Administration and the National Nuclear Power Commission and other ministries have repeatedly convened crawler crane manufacturing companies to hold meetings to encourage super-large The localization of crawler cranes has completely eliminated the status quo of human nuclear power plants.
As a leading company in the field of construction machinery, Zoomlion took on the responsibility of localizing major hoisting equipment to ensure the implementation of China's energy construction strategy. With more than 40 years of experience in designing and manufacturing cranes, Zoomlion has accumulated rich experience in key technology research, large-scale structural design, calculation and welding processing of cranes, and has a complete crane R&D and production system. 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 and renewed the maximum tonnage record. In 2009, the company successfully developed a 1000t crawler crane, which was the largest domestic lifting capacity at that time. The company's products, the company has formed a full range of 50t to 3200t products. ZCC3200NP's successful offline is the result of more than 40 years of technology accumulation in Zoomlion. It is the crystallization of the wisdom of the whole industry and is another milestone in the history of China's crawler crane industry, marking that the technical level of Chinese crawler cranes has risen to an unprecedented height.
ZCC3200NP is the world's most powerful crawler crane with the most advanced technology. This product adopts the overall solution of a double-armed frame + front and rear tracked vehicle, which breaks through the design concept of traditional crawler cranes, improves the overall stability and anti-rollover capacity of the crane, and significantly improves safety performance; in order to ensure disassembly and assembly Convenient transportation, the crane structure uses a modular design method; In order to achieve a smooth assembly of the whole machine, the design process fully considers the machining accuracy and the assembly process sequence of each file, and uses the three-dimensional animation simulation technology to complete the vehicle assembly. simulation. Taking the typical frame structure as an example, in order to guarantee the successful assembly and assembly of five large-scale box structures with multiple statically indeterminate designs, the project team has uniquely proposed the “three-reference design method for assembly of oversized frame modulesâ€. The smooth assembly of a large number of multiple statically indeterminate structures. In addition, the project team brainstormed and worked together to complete the “Study on Intelligent Control of Front and Rear Carsâ€, “Simulation and Simulation of 3D Animation of Lifting Working Conditionsâ€, “Method for Analysis of Overall Stability of Large-scale Truss Arms†and “Divable Dynamic Analysis of Post-defense System of Boom. "Study on several sub-topics." The product has more than 20 patented technologies, including many invention patents such as "Crawler Crane and its boom", "Parallel Closed Control System" and "Multi-engine Power Unit";
Prior to this, foreign companies built a solid intellectual property barrier in the field of large-tonnage crawler cranes and formed a comprehensive technical blockade. Zoomlion is a leading company in the construction machinery industry. With its strong R&D strength and first-rate manufacturing capability, Zoomlion’s ZCC3200NP project development brings together the entire company, including its two national levels, to ensure the smooth implementation of the ZCC3200NP crawler crane project. The top experts of research institutions have formed more than 100 special research groups including R&D, manufacturing, and management personnel. Through a series of independent innovations in research and development ideas, project organization, and R&D tools, the “machinery, structure, calculation, Major breakthroughs have been made in key technologies such as hydraulics, electrical and many other professional aspects.
Since 2008, a large number of market researches have been conducted for AP1000, and opinions and suggestions of construction unit experts have been actively listened to. From 2009 to 2010, multiple batches of nuclear power construction sites were inspected to understand the advantages and disadvantages of existing equipment and site usage. With regard to nuclear power construction hoisting characteristics, we consulted and exchanged ideas with nuclear power construction experts. From December 2009 to March 2010, we organized three large-scale project review meetings to widely listen to opinions from various parties, and held several internal discussions at the same time to continuously improve the technology. Program; In April 2010, Beijing invited the national nuclear power sector, machinery industry, nuclear power construction units and other experts to introduce and communicate the technical solutions. The project plan was highly appreciated by the participating experts; in 2011, the project progress was reported to the relevant national ministries. According to the actual needs of repeated modification of parameters, improve the program, Zoomlion ZCC3200NP products become the most suitable for the domestic third-generation nuclear power construction of the key lifting equipment.
Zoomlion ZCC3200NP's successful off the assembly line, once again set a record for the maximum capacity of domestic crawler cranes, making Zoomlion Station the forefront of the international crane industry, breaking the monopoly of foreign 3000 ton crawler cranes. It is of great and far-reaching significance for the national "Twelfth Five-Year Plan" to vigorously develop the high-end equipment manufacturing industry strategy and the domestic construction machinery industry's development and international status.
