The world's largest tonnage XCMG QAY1200 all-terrain crane off the assembly line

On June 25th, 2012, it took the lead in breaking the foreign technology monopoly, the world's largest tonnage, and the most technologically advanced China's first 1000-ton all-terrain crane, the XCMG QAY1200 all-terrain crane, and the newly completed Xugong large tonnage in the Xuzhou Economic and Technological Development Zone. Ground crane manufacturing base is off the assembly line. Xu Min Group Chairman and Party Secretary Wang Min and Xugong Heavy General Manager Lu Chuan, Xugong Heavy Senior Leader, XCMG QAY1200 All-terrain Crane R&D personnel, as well as industry professionals and major media attended the ceremony.

It is reported that the QAY 1200-ton all-terrain crane is based on Xugong's many years of accumulated crane technology achievements and fully absorbs advanced foreign technologies, and combines the status quo and development trends of international and domestic all-terrain cranes, using advanced design concepts and design methods. A new generation of high performance all-terrain cranes developed. It uses a nine-axis full-surface chassis, five-axis drive, all-axis steering, imported 480KW Mercedes-Benz engine power, chassis maximum speed up to 75Km / h, the maximum climbing rate of 40%, the total extension of the leg up to 13 * 13m; The QAY1200's maximum lifting moment can reach 3600t*m. The eight-section telescopic boom can reach a maximum reach of 105m and the luffing jib can reach a maximum length of 114m. The double-lifting uplifting device can effectively improve the lifting performance of the boom system. The six boom system combinations can be adapted to different operating conditions.

The QAY1200 is currently the world's largest all-terrain crane and represents the most advanced all-terrain crane manufacturing technology. Can be used for 2.5MW and below wind power installation and maintenance, petrochemical, bridges and other engineering construction, can meet the lifting requirements of many construction projects. Its large-scale all-terrain crane superlift technology, large-scale multi-axle vehicle brake integrated management technology, and large-scale all-terrain crane oil and gas suspension technology have reached the international advanced level, boom self-demolition technology, a variety of boom combination technology, modular balance Heavy technology, electro-hydraulic proportional steering technology, multi-mode multi-mode control technology, and single-cylinder latching technology have reached the international advanced level.

The successful development of the QAY1200 all-terrain crane can not only replace the import of large-tonnage all-terrain cranes, break the monopoly of foreign giants, but also adopt advanced technologies that can also be used in other industries to contribute to China’s economic development.

Located in Xuzhou Economic Development Zone, the Xugong All-terrain Crane Manufacturing Base, with an investment of 5 billion yuan and an area of ​​1,100 acres, occupies the manufacturing center of Huaihai Commercial Circle, and undertakes the production of all-terrain and medium tonnage cranes and all products. Machine coating, commissioning and starting procedures. It consists of a total of six production units, including blanking, machining, structure, assembly, painting, commissioning and rework, with 33 production lines, an area of ​​250,000 square meters, and a commissioning site of 130,000 square meters. It is currently a global scale. The largest and most reasonable layout of the R&D base for large tonnage cranes.
