Continuous medium-spanning beam bridging machine

The present invention discloses a continuous beam mid-span bridge fabrication machine, and one precast segmental construction method of continuous beam bridges made. The bridge-building machine by the front legs, guide beam, the transition section, the bent section, the main beam, bracket on pier top, and adjusting the beam suspension system, lifting off the shelf system, running the system, the electrical power system, gantry crane, the bottom mold transport car, multi-beam carrier and ancillary equipment components. The method comprises: a bridge-building unit to fight over the pier; operate a series of construction technology of beam segments on the bridge-building machines; bridge-building machine is moved by its own power before the next hole; and so forth to complete the entire construction of the bridge. With this method and apparatus having the construction speed, industrialization advantages, to meet the needs of the construction of railway bridges development; Bridging Machine self-powered device, the top surface of the movable pier construction not terrain conditions; Span adaptable minimum curve radius 600m; improving the safety and the efficiency of construction, better guarantee the quality of the construction.
