World's Largest Span Three-Tower Cable-Stayed Bridge

No.3 Main Tower of Maanshan Rail-cum-Road Yangtze River Bridge Successfully Capped

It opens a new stage of project construction.

The main bridge of Maanshan Rail-cum-Road Yangtze River Bridge is the main span.（2×1120）M Three Tower Steel Truss Girder Cable-stayed Bridge，The total length is 3360 meters，It is the world's first three-tower cable-stayed bridge with a single span exceeding 1000 meters.，It is also the longest in the world.、The Highest Highway-Railway Cable-Stayed Bridge。

No.3 main tower is the side tower of the bridge.，The tower is 308 meters high.，Wherein, the height of the concrete tower column is 217.5 meters、Steel tower part height 87.5 meters、The steel-concrete part is 3 meters high.。XugongXGT15000-600SUndertake the hoisting work of steel tower，The steel tower is prefabricated in the factory，It is divided into 13 hoisting units.，The maximum weight of a single steel tower is 505 tons.。

Facing a huge volume、Steel tower with complex structure and high requirements for construction accuracy、Construction conditions with multiple risk factors such as high safety risk，XugongXGT15000-600SThe first lifting will be carried out from the middle of April，To complete the first steel tower capping and hoisting work of the project，Reinforced concrete“The dragon”Thrive，The sound of good news also confirms Xugong.XGT15000-600SExcellent construction performance。

A workman wants to do his work well.，You must first sharpen your tools.。XugongXGT15000-600SIt is jointly developed and launched by Xugong Tower Crane and China Railway Bridge Bureau.“A great power weighs heavily”，Hoisting performance、Intelligent applications are at the top of the world.。

●The hoisting performance is strong：XugongXGT15000-600SBreakthroughMore than 60 key core technologies，Overcome more than 20 world-class technical problems，Application of 12 sets of transmission mechanisms for cooperative operation，4 Trolley+Super configuration of 4 hooks，Maximum lifting capacity 600 tons；The steel wire rope is arranged in space.，Torsion resistance increased by more than 20 times，Ensure that the 9160m super-long steel wire rope is not twisted under the super-large lifting height。

●High level of intelligence：Application of Tower Crane Coupling Check Calculation Analysis、Verification test of wall attachment、BIMDigital technology to achieve intelligent monitoring and other methods.，The installation quality and construction speed of steel towers have been improved in an all-round way.；More than 30 intelligent technologies、Specially build super tower crane intelligent cockpit，RealizationMonitoring and digital twin in the whole process of hoisting，Real-time data feedback to management and operation personnel，Escort for construction safety。
