November sixth，As the sealing material of the last anchor rod is coated,，G3 The installation of anchor rod of main cable anchorage system on the south side of Tongling Yangtze River Highway and Railway Bridge has been completed.，It lays a foundation for the next stage of main cable traction erection and tension.。In this construction，It is Zoomlion that bears the heavy responsibility of hoisting.ZCC1500VCrawler crane。

GTongling Yangtze River Rail-cum-Road Bridge is the first double-deck cable-stayed bridge in the world——Suspension cooperative system bridge，The scale of the project is large、High technology content、The construction is difficult、The construction environment is complex。The south anchorage is one of the two fixed points of the main cable of the whole bridge.，The anchoring system is the key structure connecting the main cable and the anchorage.，It plays a connecting role.，It is one of the important nodes in the construction of the south anchorage.。

To ensure the smooth construction of the anchoring system，The Project Department shall organize experts to review the construction scheme.，Scientifically formulate the node construction period，During construction of the anchoring system，Anchor bolt is an important part of the system.，With large construction volume、High difficulty in hoisting。

The person in charge of site construction said.：“The most difficult thing in anchor installation is to control the tilt angle.，Ensure that all anchor rods are uniformly stressed。To precisely control the installation angle，We introduce innovationBIM3D model，Find the center of gravity of the anchor rod，The lifting angle of the anchor rod is fixed by a uniquely designed lifting tool.，Then in ZoomlionZCC1500VLifting construction is carried out with the help of crawler crane and other lifting equipment.，This not only ensures the accuracy of anchor rod installation，At the same time, it saves the time of complicated angle adjustment in the installation process.，And greatly improve that hoisting efficiency.。”

With the help of Zoomlion crane on site，Since the first anchor rod was installed on September 26,，A total of 218 anchor rods were installed in only 42 days.，20 days ahead of schedule，Refreshed again“G3”Speed of construction。

According to introduction，ZCC1500VThe crawler crane has a large gauge of 6 meters.，Lifting torque up to 906.5 tons of meters，Better performance；Weichai is adoptedWP10 Engine，180TClass travel device，The match is stronger；At the same time，Its main machine has a transport weight of 35 tons.，Transport width 3 m，It is more convenient to dismantle and transport。In addition，ZCC1500VThe crawler crane also has omni-directional monitoring.、Intelligent management、Functional advantages such as perfect safety control，It is very suitable for large-scale hoisting of major projects.。

DivideZCC1500VCrawler crane andZTC251V、ZTC350H、ZTC500HTruck crane and other engineering lifting equipment，Concrete pumping machinery of Zoomlion、Tower cranes and other equipment also provide a strong boost to the project.。Before，GThe No.3 main pier bearing platform of Tongling Yangtze River Highway and Railway Bridge completed the last concrete pouring with the help of Zoomlion pump truck.，As a result, the bridge has fully entered the construction stage of the main tower pier body.。
