The six batch of equipment involved in the construction of Sichuan Guanghe bridge construction

Recently, Sichuan built four C7030 tower and four SC200/200WPZ construction elevator to participate in the six river bridge construction, make a positive contribution to China's bridge construction.

Xifeng to Qianxi Expressway in Guizhou Province, "678" the highway network "three horizontal" is an important part of construction projects to improve the highway network in Guizhou, drive the construction of Economic Zone in Guizhou, has important meaning to build the core area of Guizhou Economic Zone Highway link etc..

Guizhou high-speed six Guanghe bridge bearing is designed for over six river canyon, bridge to reach a total length of 1280 meters, the main span of 580 meters of Twin Towers and double cable plane composite cable-stayed bridge.

The six batch of equipment involved in the construction of Sichuan Guanghe bridge construction

Six Guanghe bridge is the most important in the whole freeway, is also the most difficult construction control project, both sides of the pier height is 242 meters, each pier crane configuration are built of Sichuan produced two sets of C7030 tower and two SC200/200WPZ medium frequency construction ladder.

Take the main construction hoisting C7030 tower crane, a maximum weight of 16 tons, lifting height of 273 meters and 256 meters two sets of tower crane, the working range of 70 meters and 50 meters, cross section layout, large coverage, tower 2.5 meters, the main form of the rod string, mechanism configuration adopts stepless variable frequency speed control system, start-up, smooth braking, lifting mechanism adopts double brake, increase safety and reliability of hoisting, lifting drum large capacity domestic initiative and won the national utility model patent, the multilayer lifting steel wire rope winding, the ultra-high tower crane wire rope rope can be long neat, smooth operation.

The two construction lifts for manned and lifting objects are all 248 meters, 3 x 15kW three, motor drive, rated speed up to 0~55 m/min, and cable form adopts sliding contact mode, which solves the problem of cable self weight load of super high lift hoist.

The effective arrangement of Sichuan building tower crane and construction elevator, greatly enhance the work efficiency, to cooperate with the construction side rush period, grasp the progress, timely completion of the construction of six Guanghe bridge, laid the foundation for early realization of Guizhou Expressway opened to traffic information.
