Products THQ series machine is the central bridge over the tunnel was built for high-speed rail construction machines encountered in multi-tunnel project and developed a new high-speed rail bridge machine, the machine can be shipped directly from the beam haulage vehicles through the tunnel, reducing the erecting machine and transporting girder vehicle repeatedly dismantling costs, but also ensure construction safety, suitable for continuous tunnel bridge bridge construction site use. Product Features 1, you can build bridges and tunnels connected and works to reduce the repeated assembly and disassembly costs, improve construction efficiency. 2, lifting system uses a four-point fixed Lifting beam, load balancing, ensure the safety of their own concrete box girder structure and lifting systems, by starting vertical hoisting mechanism, sliding fine-tuning can be achieved when accurate box girder place. 3, each guide beam and erecting machine guidance, vertical shift vias, simple operation, safe and reliable. 4, can achieve change across erection, erection can be achieved curve segments, tire transporting girder trolley girder machine directly mule overall structure, to achieve erecting machine transitions, through the tunnel and the tunnel erected in place. 5, through the guide beam and guiding beam hanging shift car, with auxiliary crane, bridge machine can achieve the first, the last girder erection holes and tunnels export beam.
