Product description
Bridge Girder Erecting Launcher Crane applies to highway, railway bridges to the construction site of bridge construction, its main function is to mention prefabricated good beam slice and delivered on prefabricated good piers.it and general meaning cranes have very big different, high safety requirements.

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 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 foldabletechnology. The "C" shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.

Features

  • 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 .
  •  High efficiency.

Safety Features:

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. 
Voltage lower protection function .
Phase sequence protection function. 
Emergency stop function. 
Rain cover for outside hoist, driving units, electric cubicle. 
Warining indicator : flashing nights and warning sounds. 
Wire-less infra-detector for anti-collusion.

Configuration:

Construction Process:

 
 
1.U beam precast yard
Do U type beam in the beam yard
  2.U beam precast yard
The precast u beam placed in the beam yard
 
3.Lifting beam
Put precast beam to the transporting girder car
  4.Transport
The transport car is transporting precast beam to the construction site

 
5.Girder erection
Using gantry crane lifting beam to pier
  6.Beam feeding
The car transport beam to beam launcher
 
7.Beam launcher
Trolley lifting the precast beam
  8.Beam launcher
The beam launcher setting on the beam
