Bridge girder launching gantry
1.100t-30m span Truss Type Bridge Launcher Girder Crane
3.Working Class: A3
4.Lifting Height: 7.5m
5.ISO Passed and CE certificate.
1.100t bridge trussed launching girder Adopting full-hydraulic
lifting mechanism with high reliability as front and rear
supporting point to ensure the safely of supporting points.
2.Lightening and great rigidity design of guiding beam to ensure
the longitudinal stability of the machine.
3.Strengthened front,middle and rear crossbeams guarantee rigidity
of the complete machine and make the through-hole more
stable.Specially designed reaction wheel body makes through-hole
4.100t bridge trussed launching girder Adopting adduction type
integral legs to ensure the security of erecting edge beam to place
at one time.
5.Skew erection for skew bridges,connection parts of each mechanism
and structure all use rotating face flange for coupling,can used
for erecting skew bridges of any angle from 0-45C.
6.The machine of 100t bridge trussed launching girder can erect 4
pieces of girders with the other two cranes one day,reducing
Railway bridge girder launching gantry is a walking type product
and is one of our newly developed products. The bridge erecting
crane is special equipment for railway with wide operating range,
excellent performance, easy operation and safe structure. Its main
structure features are that main girder is designed with a four
sides truss structure, and is welded using structural steel and
steel plates to provide a lightweight and strong wind resistance.
This product is designed to suit the building of high gradient,
small radius curved bridges, 45 degree inclined bridges and bridges
near tunnels. It also makes construction on plains areas much
easier. This product is suitable for working in the environment of
no fire, no explosion and no corrosive media with temperature from
1. the machine can accomplish the build of girders with carrying
and erection at the same time.
2. the machine can erect 4 pieces fo girders with the other two
cranes one day, reducing construction cycle.
3. the machine can continue to work just exchanging the front rear
legs, no need extra assembly.
4. Unique honeycomb-girder structure, low deflection and high
5. Put boundary beam in place one time when it has a side load.
without hanging landing leg in the air, safe and reliable
6. If the landing leg front and back is changed a little, it can
erect the bridge in a reverse direction
7. The error of bridge girder erection is less than 5mm
8. Unique pin connection, firm and reliable, easy to install
9. A-type fracture surface, continuous girder with low center of
gravity, convenient and reliable.
1. work altitude ≤2000m
2. work ambient temperature:-25°C~+40°C
3. the equipment will not be damaged under non work condition of
-40°C extreme environment
4. allowable maximum wind pressure in working condition: girder
erection:6 grade, cross piers: 5 grade
