bridge girder launcher

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 stiffness

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.

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 . 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.

We researched and developed JQI 80 / 30 inclination-cross bridge girder erection machines by ourselves in 1998. The flexibility and quickness of these products have been approved. Advantages of these products include: safe, light in weight, invested little, and easy to assemble, disassemble and maintain.

Crane girder:

The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!

Safety features:

1. Overload protection: If the material is over the capacity, the crane will give a sharp warning for protection itself.

2. Emergency brake: If the operation staff encounter some emergency situation, we could start the emergency brake system to protection the related treasure.

3. Control Method: Room control or remote control to avoid any injure to the operation staff

4. Main lifting motor: with thermal protection and currency protection.

Design and construction rules:

All the standards which is required for the crane is the Chinese standard
