■ Specifications

(1)Bridge launcher girder machine description:

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 operation full-automatic. 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 construction cycle.

(2)Bridge launcher girder machine main feature/advantages:
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 stiffness5. Put boundary beam in place one time when it has a side load. without hanging landing leg in the air, safe and reliable6. If the landing leg front and back is changed a little, it can erect the bridge in a reverse direction7. The error of bridge girder erection is less than 5mm8. Unique pin connection, firm and reliable, easy to install9. A-type fracture surface, continuous girder with low center of gravity, convenient and reliable.

(3)Bridge launcher girder machine working condition

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
