A bridge connects Sichuan and Yunnan! Zoomlion R Generation Tower Crane Helps Build "the First High Bridge in Sichuan"

At the beginning of the new year，Many major projects in China ushered in important construction nodes。Recently，In ZoomlionRWith the help of the Tower Crane，The highest cable tower under construction in Sichuan、Cable-stayed bridge with maximum span——Successful Hoisting of Steel Truss Girder of the First Segment of Xinshi Jinsha River Bridge along the Yangtze River Expressway，It marks the full development of the erection of the steel truss girder of the bridge.，It formally entered the key stage of the main steel truss girder erection.。

“R800-40WThe tower crane is mainly used for hoisting steel box girders and stay cables in this project.，It has anti-collision.、The sleeve frame is prevented from falling off、Hook video and other functions，Facing the narrow construction site，The construction efficiency and convenience are greatly improved.。At the same time，It also integrates remote device debugging、Remote intelligent control、Intelligent features such as remote safety supervision，The device is realized、One-stop intelligent management of projects，It ensures the safety and efficiency of construction.。”Zoomlion built a field service engineer said.。

At present，The construction of the Jinsha River Bridge in the new city along the Yangtze River is accelerating.，It is expected that the bridge deck will be closed as soon as the end of next year.，Zoomlion tower crane will also continue to achieve“One bridge connects Sichuan and Yunnan”Provide reliable support for the vision of。
