According to the science and technology daily, the w12000-450 tower crane used for the hoisting construction of the North Main Tower of Changzhou Taizhou Yangtze River Bridge has been officially put into use. this equipment is the first 10000 ton meter upper slewing tower crane developed in the world. Changtai Yangtze River Bridge is the first river crossing channel integrating expressway, intercity railway and highway. Its main channel bridge adopts steel truss cable-stayed bridge with a main span of 1176m.
Access:
The main tower adopts the "steel-concrete" hybrid structure space diamond shaped four tower limb bridge tower, with a total design height of 352m, which is the world's first high cable tower.
According to the limit hoisting construction conditions of the main tower of the bridge, it is necessary to hoist the 240 ton bridge tower section to a height of 350 meters at a range of 35 meters.
Previously, there was no tower crane on the market to meet this demand, so it could only be customized. Therefore, w12000-450 tower crane is generated.
It is understood thatw12000-450 tower crane has a rated lifting moment of 12000t / M and a maximum arm length of 75m The maximum lifting weight is 450 tons and the maximum lifting height is 400 meters, which is equivalent to the height of 300 cars to 130 floors at one time.
As the world's first developed ten thousand ton meter upper slewing tower crane, it has been tested and demonstrated for many times in design scheme review, manufacturing and processing, on-site assembly, load test, etc** Its performance fully meets the construction requirements of Changtai Yangtze River Bridge.
It is reported that w12000-450 tower crane was jointly developed by CCCC Second Harbor Engineering Co., Ltd. and Zoomlion. It took only 10 months from the demand to the offline.
