Recently, Jiangsu Changtai Yangtze River Bridge Project plans to use the heavy equipment of the big country for the hoisting and construction of the north main tower of the bridge - the W12000-450 tower crane jointly developed by CCCC Second Aviation Bureau and Zoomlion was officially put into use.

According to the hoisting construction conditions of the main tower of the bridge, the 240-ton bridge tower section needs to be hoisted to a height of 350 meters at a range of 35 meters. Previously, there was no tower crane that met this demand on the market, and it could only be customized for it. The W12000-450 tower crane has a rated lifting moment of 12,000 tons m and a maximum boom length of 75 meters. It is the world's first super-large tower crane with a top-turn over 10,000-ton meters. Its maximum lifting weight reaches 450 tons and the maximum lifting capacity The height is 400 meters, which is equivalent to lifting 300 cars to a height of 130 floors at a time.

After the 10,000-meter-level tower crane has completed the task in the construction of the Changtai Yangtze River Bridge project, it will be transferred to Anhui to invest in another super project - the Chaoma Intercity Railway Ma'anshan Highway and Railway Dual-purpose Yangtze River Bridge.Editor/Ma Xue
