OverheadLaunching Gantry
Our overhead launching gantry is suitable for theconstruction 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 specialbridges.
Descriptionsof Overhead Launching Gantry
1. The main girder of our overhead launchinggantry 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 toassemble.
3. The honeycomb hole in the middle of beam can greatly reduce the impact ofwind on the beam.
4. The weight of our honeycomb beam launching gantry is between the weight ofbox girder and truss girder.
5. This launching gantry can adopt single beam side load lifting, and itssupporting 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 gantryhave the features of light weight, high strength, low defection, andhigh wind resistance.
2. Unique steel pin connection, which is not only firm, but also easy toinstall.
3. Electronic measurement and control devices can be installed as per users'need.
