2.Bridge Girder Launcher Details
customized 800ton beam launcher bridge erection 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.
customized 800ton beam launcher bridge erection is widely used in highway and railway 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 foldable technology. The "C" shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.
3. Installation process:
Unique pin connection, firm and reliable, easy to install
A-type fracture surface, continuous girder with low center of gravity, convenient and reliable.
The machine can accomplish the build of girders with carrying and erection at the same time.
Low deflection and high stiffness .
Safe and reliable .
Safety is the most important issue for cranes.To ensure the safety,the following safety devices are equipped in BL crane.
Crane traveling limit switch.
Overload protection device.
Lifting height limit device.
