DF Multi-purpose Highway Launching Gantry

In March 2011, our company launched the DF multi-purpose highway launching gantry. This equipment is suitable for erecting railway girder of 2201, 2101 and 9753 types and for laying railway track panel with the length of 25 meters. It is also applicable to the erection of highway T-shaped girder with the weight less than 180 tons and the length less than 40 meters.

Adopting a new structure, this highway and railway launching gantry can feed a beam onto a beam, so the distance between the rail surface and the bottom surface of main beam is 3.15 meters during girder erection, greatly improving safety of the equipment.

Our launching gantry can meet various operating conditions of railway bridge construction, such as small curve girder erection (R≥600m), girder erection at tunnel portal and inside the tunnel. The whole equipment is carried by a flat car, which satisfies the requirement of railway clearance.
