Changde, China, October 28, 2021/PRNewswire/ - The world's largest top-slewing tower crane W12000-450 rolled off the production line of Zoomlion's intelligent tower crane manufacturing base. Co., Ltd. ("Zoomlion"; 1157.HK) is located in Changde City, Hunan Province. Zoomlion has specially designed and built a model for the Changtai Yangtze River Bridge, the world's largest highway-rail cable-stayed bridge project, which integrates expressways, ordinary highways and intercity railways.

W12000-450 weighs 4,000 tons and has a rated load moment of 12,000 ton meters. It is the world's first top slewing tower crane with a maximum lifting capacity of 450 tons and a maximum lifting height of 400 meters, which exceeds 10,000 tons. It is equivalent to lifting 300 cars to a height of 130 floors. go.

The key technologies for the construction of super large tower cranes are complex and require high safety and reliability. Zoomlion has the courage to challenge technological innovation and manufacturing requirements, to explore the unknown and set new records.

"In the absence of structural rules to follow, we re-established the calculation platform for structural stiffness, stability and modal analysis," said Tang Shaofang, vice president of Zoomlion and general manager of Zoomlion Engineering Hoisting Machinery Company. . "The W12000-450 tower crane adopts a number of independent research and development technologies of Zoomlion, including full penetration T-joint welding technology, which overcomes technical difficulties such as weld cracking of ultra-thick plates, making W12000-450 not only super-strong While the lifting performance reaches the 10,000-ton-meter level, it also ensures the safety and reliability of the entire transportation, assembly/disassembly and operation process."

W12000-450 is produced in the world's largest smart tower crane factory. According to the plan, the plant will produce construction crane products ranging from 80 to 20,000 tons. Fully digital, integrating big data analysis, industrial Internet, information systems, visualization, etc., to achieve full coverage of networking and human-computer interaction.

With smart and flexible assembly tools, W12000-450 can be manufactured in four months, while traditional manufacturing technology requires at least 12 months.

As building components are getting heavier and heavier, buildings are getting taller, and bridge spans are getting larger and larger, the demand for super-large tower cranes is increasing. The launch of W12000-450 will not only bring the latest solutions to the heavy industry, but will also showcase Zoomlion’s industry-leading capabilities in the R&D, design and manufacturing of large tower cranes.
