The south main tower of Maanshan Yangtze River Rail-cum-Road Bridge was successfully capped, and the world's largest tower crane of Zoomlion was built again.

Recently，With the world's largest Tower Crane——ZoomlionR20000-The 720 will weigh 88.The 3-ton steel tower segment is precisely hoisted to the No.5 main tower at an altitude of more than 300 meters.，It marks the world's largest span three-tower cable-stayed bridge.——South Main Tower of Maanshan Yangtze River Rail-cum-Road Bridge Successfully Capped，Breakthroughs have been made in project construction.。

The capped south main tower is made of steel.-Mixed structure，TransverseAType、The longitudinal direction isIShape structure，Wherein the middle tower column、The lower tower column is a concrete double-leg structure.，High 218.5 meters；The upper pylon is of steel structure.，High 87.5 meters。ZoomlionR20000-720 Tower Crane overcomes the high risk of high-altitude operation、High standard of construction technology、The construction of interchange is difficult.，Successfully completed the capping and hoisting task，It has laid a solid foundation for the bridge to enter the next construction stage.。

Ma'anshan Yangtze River Rail-cum-Road Bridge is the control project of Chaozhou-Ma'anshan Intercity Railway.，The total length is 3248 meters，It is the world's first three-tower cable-stayed bridge with double main spans exceeding 1000 meters.、World's Largest Span Three-Tower Cable-Stayed Bridge，It is also the longest steel truss cable-stayed bridge in the world.。R20000-720 is specially developed by Zoomlion for large bridge construction.，The rated lifting moment is t/m 20000.，Maximum lifting capacity of 720 tons，Maximum lifting height 400m，Capable of strong winds、High humidity、Operation under complex extreme working conditions such as heavy load，Not only“The largest in the world” Still “The strongest in the world”。

▲ZoomlionR20000-720 is under construction in Maanshan Yangtze River Rail-cum-Road Bridge Project

Since September 1, 2023, it has been constructed in Ma'anshan Yangtze River Highway and Railway Bridge Project.，ZoomlionR20000-720 Full display of intelligence、Precise、Smooth performance benefit，Successfully completed the project hoisting task for many times，It provides powerful equipment support for the smooth construction of the bridge.。

Next step，The Ma'anshan Yangtze River Rail-cum-Road Bridge will carry out the cantilever assembly of the mid-span steel truss girder and the installation of 198 super-strong stay cables，It is expected that the steel beam closure will be completed in June next year.。Zoomlion will continue to provide hard core strength for bridge construction，To further improve the layout of China's regional high-speed railway network、Promote the integrated development of the Yangtze River Delta and contribute to the development of the Yangtze River Economic Zone.。
