900T Bridge Construction Gantry Cranes is a new type of high-speed railway bridge erection machine developed by Sinoko cranes for the multi-tunnel project encountered in the construction of high-speed railway. Main features as following:
(1) Suitable outdoor dusty environments
(2) Heavy capacity
(3) Huge construction projects
(4) Long life span and multiple times appliation
Sinoko crane is focusing on the development of bridge erection machine for many years. Bridges and tunnels can be set up to connect and work, reducing the cost of multiple disassembly and assembly and improving construction efficiency. The lifting system adopts four-point fixed lift beam, which is balanced by load to ensure the safety of the concrete box girder and the lifting system's own structure. Through the vertical and horizontal fine adjustment of the lifting mechanism, the accuracy of box girder erection can be achieved
1. Bridges and tunnels can be set up to connect and work, reducing the cost of multiple disassembly and assembly and improving construction efficiency.
2. The lifting system adopts four-point fixed lift beam, which is balanced by load to ensure the safety of the concrete box girder and the lifting system's own structure. Through the vertical and horizontal fine adjustment of the lifting mechanism, the accuracy of box girder erection can be achieved.
3. Guiding beam and bridge erector guide each other and move through the hole vertically. The operation is simple, safe and reliable.
4. It can realize variable-span erection and can realize the erection of curve sections. The tire-type beam-carrying trolley can directly transport the overall structure of the beam-beaming machine to realize the erection of the bridge-transporting machine, crossing the tunnel and positioning the tunnel entrance.
5. Through the guide girder and the guide girder to lift the trolley and the auxiliary crane, the erection of the bridge head, the end hole beam and the tunnel entrance and exit beams can be realized.
