JQDS900 Tunnel Bridging Machine could work together with the supporting low-post beam truck to transport and erect box girder of high-speed railway. The parallel operation mode of bridging machine and girder-transporting vehicle is adopted. After the beam is loaded in precast yard, it will be transported to the tail of the bridge machine through the access road, roadbed, bridge and culvert, and then bridging machine will erect box girders.
