Application range of box girder beam launcher for girder carrying and erecting
HZQY900B box girder beam launcher is a kind of device used for the lifting, transporting and erecting 900t box girder for high-speed railway passenger dedicated line. The machine can pass the tunnel of two lines with the whole concrete box girder 20m, 24m and 32m.There are lots of methods for it to erect girder in the entrance of the tunnel, inside and outside the tunnel. It can lift and transport the box girder to move and erect girder on the construction road, road base and the well-erected box girder and it will not cause any damage to the above facilities. It can erect bridge pier in the front or back of the girder prefabricating field without the problem of field changing.
Main features and advantages of box girder beam launcher for girder carrying and erecting
1.The machine combines girder lifting, transporting and erecting.
2. Compared with the traditional beam launchers, it can erect girder successfully without the help of the lower guide girder and any other auxiliary equipment. It has light and simple structure. The operating procedures is simple with high safety.
3. It can lift and transport the full span box girder of two lines passing through the tunnels of 250km/h and 350km/h. It also can erect girder in the entrance of the tunnel and inside the tunnel.
4.It is easy for the machine to erect the first and the last girder before the machine entering the tunnel.
5. The span of the whole machine can be changed easily with strong ability to apply the work environment.
6. Any part of the machine does not need to be fixed with anchors in the process of girder erecting, thus reducing the erecting steps and improving safety.
