On February 28, 2023, the XGT15000-600S, the world's largest tower crane jointly developed by China Railway Major Bridge Bureau and Xugong Group, smoothly hoisted an object weighing more than 660 tons on the west side of the No. 6 main tower of Changtai Yangtze River Bridge to nearly At a height of 100 meters, it successfully passed the dynamic load test organized by Changzhou Branch of Jiangsu Provincial Special Inspection Institute, marking that the world's largest tower crane has been put into the construction of the world's largest span road-rail dual-purpose cable-stayed bridge Changtai Yangtze River Bridge.
The XGT15000-600S tower crane has a rated lifting moment of 15,000t.m, a rated lifting capacity of 600 tons, a lifting height of 400 meters, and a lifting range of 61 meters. It is currently the world's largest horizontal jib slewing self-elevating tower crane.
On June 2, 2022, the XGT15000-600S tower crane tailored for the Changtai Yangtze River Bridge was rolled off the production line in Xuzhou, Jiangsu Province, and delivered. This tower crane will serve the construction of the upper column of the No. 6 main tower of the Changtai Yangtze River Bridge, effectively solving the project hoisting Construction difficulties such as heavy components, high construction height, and large operation span.
According to Fang Lin, technical director of the construction site of the main tower, the designed total height of the main tower of the bridge is 352 meters, which is divided into lower tower, middle tower and upper tower. Different from the previous section-based pouring of concrete for the middle and lower tower columns, the upper tower column is hoisted in blocks of steel towers and welded on site to form an overall scheme. It is divided into 10 sections and will be hoisted 33 times. 323 tons.
At present, the tower crane has been raised to 250 meters, and then the tower will gradually grow taller with the main tower. When the main tower is capped, the tower crane will rise to 379 meters. This height will break the height of the tower crane in the field of bridge construction. record. Editor / Zhao E
