Bridge Girder Erecting Launcher Crane mainly consisted with main beam, cantilever, under guide beam, front and rear legs, auxiliary outrigger, hanging beam crane, cantilever crane and elecrto-hydraulic system. Applies to three different span single-span simply supported beam erection, with high operating efficiency
Bridge Girder Erecting Launcher Crane applies to highway, railway bridges to the construction site of bridge construction.
This Machine is used for erecting concrete box girders for high speed (250km, 350km) passenger railway lines. This machine is suitable for equal span girders or different span girders which can be 20m, 24m and 32m, 50m. The rear part has two supports. One of the supports is "C" shape column with rotary and foldabletechnology. The "C" shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.
