Professional Design Bridge Beam Launcher Features

 

The main beam adopts a truss structure, which has the advantages of light weight, large load, and strong wind resistance.

Adopting walking forward, the middle outrigger does not walk on the bridge deck, so there is no need to erect a longitudinal moving track. This can save construction costs and improve erection efficiency.

The outrigger has an adjustable angle core plate, which can adapt to the inclined bridge at any angle below 45°.

Optional: frequency conversion to adjust speed

Optional: safety monitoring, PLC control
