Guide: at 12:00 noon on August 12, Zoomlion independently developed and manufactured the world's largest up slewing self elevating tower crane D. in the main tower project of Ma'anshan Yangtze River Bridge undertaken by China Railway Bridge Bureau, witnessed by industry media and Anhui special equipment supervision and inspection department, Successfully lifted 240.5 tons of

8 the stable production capacity in large quantities is less than 12:00 p.m. on August 12. Zoomlion independently developed and manufactured the world's largest up slewing jack up tower crane d to confirm the accuracy of the experimental machine. In the main tower project of Ma'anshan Yangtze River Bridge undertaken by China Railway Bridge Bureau, under the witness of industry media and Anhui special equipment supervision and inspection department, it successfully lifted 240.5 tons and conducted various load test assessments. After the assessment of the authoritative department, the d5200 tower crane operates smoothly in the process of lifting with a maximum tonnage of 240.5 tons, and the load capacity and various functions of the tower crane fully meet the calibration requirements

this successful lifting is the first scientific and rigorous verification of the extraordinary strength of the world's largest upward rotating horizontal arm tower crane in front of the world. It is another phased achievement of the d5200 tower crane project

the successful lifting of d5200 tower crane is at an independent height of 90 meters, a range of 22.15 meters, a lifting weight of 240.5t, a lifting torque of 5411 ton meters, and a total load and luffing time assessment time of nearly two hours

Dai Xianrong, executive deputy manager of Ma'anshan Yangtze River Bridge Project Department of China Railway Bridge Bureau, witnessed the debut of d5200 in the bridge project. He said excitedly, "through this successful assessment, we are full of confidence in Zoomlion d5200. We believe that he will be able to help us complete the largest lifting at the end of November this year, lifting 210t lifting weight at a height of 205 meters."

with the development of domestic infrastructure installation projects towards large-scale, efficient and safe, and the construction of bridges, power plants, wind power, chemical industry and high-rise buildings, the demand for large-scale tower cranes shows a rapid development trend. The tower of Ma'anshan Yangtze River bridge constructed by China Railway Bridge Bureau Group in Ma'anshan, Anhui Province is a multi-section steel structure. The bridge tower is composed of dozens of sections, of which the heaviest section is 210 tons and the installation height is 205m. After repeated and multifaceted comparison and selection of the construction scheme, it is finally determined to use the tower crane for installation, which can safely and smoothly carry out the construction on the premise of ensuring the construction quality of the project, and also meet the construction period requirements proposed by the owner. Compared with other types of tower cranes, the up slewing horizontal boom tower crane has the characteristics of high efficiency and light weight, and its comprehensive economic indicators can meet the construction requirements of Ma'anshan Yangtze River Bridge. Therefore, the newly developed type of tower crane is determined as the up slewing scheme of horizontal boom

through field visits and frequent technical exchanges, China Railway Bridge Bureau has a deep understanding of Zoomlion. On March 22, 2010, Zoomlion signed a d5200 procurement contract with China Railway Bridge Bureau; On August 29, d5200 was successfully offline; In December, d5200 was delivered to the Ma'anshan Yangtze River Bridge project of China Railway Bridge Bureau for installation

Zoomlion is a leading enterprise in China's construction machinery industry and the world's largest tower crane manufacturer. It has sufficient technical reserves in the field of research, development and manufacturing of super large tonnage tower cranes. China Railway Bridge Bureau has a leading position in the bridge industry in China and even the world. It is of great practical significance and far-reaching historical significance for the two enterprises to work together to jointly innovate China's bridge construction technology and tower crane technology. At present, there are few fatigue testing machines specially for flat nest coil springs in China. 520 the pointer of its dynamometer vibrates or jumps. Less than a year after its birth, the test and assessment of the maximum lifting weight has been completed, which marks that the situation that China's bridge large tonnage structure and ultra-high hoisting projects rely on imported tower cranes for a long time has been completely rewritten. It is not only the pride of China's tower crane manufacturing industry, It is also the pride of China's construction machinery industry
