Big Country Heavy Equipment Joins Big Country“League building”，Super engineering guarantee is more sufficient

Shiziyang Bridge is the key control project of Shiziyang Passage Project.，The bridge adopts a double-deck steel truss suspension bridge with a main span of 2180 meters.“As soon as you cross the river”，It is the most difficult technology in China and even in the world at present.、One of the most complex bridges ever built，After completion, it will become the world's largest span double-deck suspension bridge.，Creation of main span of double-deck suspension bridge、Number of lanes、The main tower is high、Anchor foundation、The main cable scale is the first in the world in 5 items.。

Before，Construction cranes are available at the project site.、Concrete pump truck、Rotary drilling rig and other Zoomlion equipment depth assistance，The world's largest tower craneR20000-The addition of 720，It will provide more solid equipment guarantee for the project construction.。

The total lifting weight is equivalent to more than 100 domestic large aircraft.，Many meritorious deeds have been made in assisting the construction of projects

Before the Shiziyang Bridge Project，R20000-720 has been applied in Maanshan Yangtze River Rail-cum-Road Bridge of Chao-Ma Intercity Railway，And with strong lifting capacity and high accuracy.、High security、High intelligence，He has repeatedly performed meritorious deeds。Maanshan Yangtze River Rail-cum-Road Bridge on Chaozhou-Maanshan Intercity Railway 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.。

Since September last year, the first section of steel tower hoisting has been successfully completed.，By January this year, the south main tower of the bridge was successfully capped.，R20000-720 in a strong wind、High humidity、Under complex extreme working conditions such as heavy load，Overcome the high risk of working at height、High standard of construction technology、The construction of interchange is difficult.，Successfully completed the hoisting of key nodes one after another，The smooth progress of the project has been guaranteed.。

The relevant person in charge of the Zoomlion project said.：“All the steel tower sections of the south main tower of Maanshan Yangtze River Highway and Railway Bridge are ours.R20000 for hoisting，The total weight of hoisting is more than 4600 tons.，Weight equivalent to more than 100 domesticC919 large aircraft。In March this year，R20000 after the completion of the construction task of the Maanshan Yangtze River Rail-cum-Road Bridge on the Chao-Ma Intercity Railway，He rushed to the construction site of Shiziyang Bridge without stopping.，Continue to contribute to the super project。”
