Our overhead launching gantry is suitable for the construction of highway, railway bridges whose span is less than 60 meters, bending deflection is within 5 degrees, and gradient is no more than 5%. According to customers' requirements, it can also be used to build special bridges.
Descriptions of Overhead Launching Gantry
1. The main girder of our overhead launching gantry is welded from beams with triangle section, with low center of gravity.
2. The beams are interconnected at their ends via six steel pins, easy to assemble.
3. The honeycomb hole in the middle of beam can greatly reduce the impact of wind on the beam.
4. The weight of our honeycomb beam launching gantry is between the weight of box girder and truss girder.
5. This launching gantry can adopt single beam side load lifting, and its supporting legs are not hanging in the air.
6. During launching, the machine can move freely, with high erection accuracy (error ≤5mm).
Features
1. Our overhead launching gantry have the features of light weight, high strength, low defection, and high wind resistance.
2. Unique steel pin connection, which is not only firm, but also easy to install.
3. Electronic measurement and control devices can be installed as per users' need.
