World's Largest Span Double-Deck Suspension Bridge——Shiziyang Bridge
Welcome new construction“Super Assistant”!
Recently,Zoomlion, the world's largest Tower CraneR20000-720
Complete the erection of the tower at the west cable tower of the bridge
Before,Zoomlion crane、Pump Truck、Rotary Drilling Rig, etc
It has provided a strong boost for the construction of this super project.
Tower Crane King Starts a New Journey
The Shiziyang Bridge is 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.。

This is the world's largest Tower Crane, Zoomlion.R20000-720 once again helps world-class bridge engineering。Arrive at Shiziyang Bridge Project,R20000-720 has been successfully applied in Maanshan Yangtze River Rail-cum-Road Bridge of Chao-Ma Intercity Railway,Successfully completed the hoisting task in the construction of the world's largest span three-tower cable-stayed bridge,With powerful lifting capacity and high accuracy、High security、High intelligence has won praise repeatedly。
▲World's Largest Tower CraneR20000-720 to help build Ma'anshan Yangtze River Highway and Railway Bridge
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.,The smooth progress of the project has been guaranteed.。According to introduction,All steel tower sections of the south main tower of Maanshan Yangtze River Rail-cum-Road Bridge are composed ofR20000-Hoisting of 720 tower crane,The total hoisting weight exceeds 4600 tons.,Equivalent to more than 100 domestic aircraftCThe weight of the 919 aircraft。
A big country's heavy weapons and force“League building”
R20000-After 720, the hoisting of the west cable tower section of the bridge will be carried out.,Push the main tower“Jointing and growing tall”。Before,Various types of equipment of Zoomlion have entered the site.,It has laid down a lot for the construction of the bridge.“You have made great contributions”。
▶ Construction hoisting machinery
At the construction site of east anchorage diaphragm wall of Shiziyang Bridge,Zoomlion's 400-ton Crawler Crane and 260-ton Crawler Crane cooperate in operation、Two-way resultant force,The huge steel cage of more than 100 tons was turned 90 degrees vertically from the horizontal position.,And conveyed to the notch to be vertically lowered.,Let“Steel skeleton”Successfully hoisted into the slot。
▶ Construction hoisting machinery
There is more than one Zoomlion super-large tower crane on site.。R6600-240 Take the lead in hoisting the steel shell of the first segment of the east cable tower of Shiziyang Bridge,The steel shell with a single weight of about 119 tons was precisely and stably hoisted to the temporary storage point.。
East of Shiziyang Bridge、The diameter of the west anchorage foundation pit is 127 meters respectively.、130 meters,The total concrete pouring volume is as high as 520,000.、550,000 cubic meters。Facing the complex construction environment、Large volume of single pouring、Long time and other challenges,Many pump Trucks of Zoomlion are stable and reliable.、Excellent performance of energy saving and high efficiency。
The pump Truck of Zoomlion is also responsible for the right tower base of the west cable tower of the bridge andTPouring of tower column of segment 1。The field operator said:“Not only is the boom stable、Beat the material quickly,And fuel-efficient,The key is to fightCThe ash of 80 is not difficult at all.!”
▶ Foundation construction machinery
The two main towers of Shiziyang Bridge are provided with 132 pile foundations in total.,3 meters in diameter,The east cable tower pile is about 50 meters long.。Zoomlion Rotary Drilling RigZR550GParticipate in the pile foundation works of the east cable tower of the bridge,O as to efficiently form holes、High Verticality Helps Ensure Project Construction Progress and Quality。
