ASAP China steel materials concrete box bridge girder launcher
- 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
- 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.
Parts Of Crane
- 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 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
