Bridge girder erection machine belongs to lifting equipment, and its main function is to lift the beam, and then transport it to the needed position. In short, bridge girder launcher crane is a lifting device that transfer the prefabricated beam to certain piers. However, launcher girder crane differs from general crane to a large degree, and its working condition is harsher than other types of lifting equipment, such as anti-explosion overhead crane, suspension crane and bridge crane for sale.

Bridge girder erection equipment is generally divided into highway bridge erecting machine, railway bridge building machine and high-speed railway bridge making machine. Bridge beam launcher has complex structure than other types of crane, which mainly includes the main beam, machine arm, a lifting trolley, columns, hydraulic system, electrical system, moving tracks, diesel generator and safety monitoring system.

The main girder of bridge building machine in china adopts triangular truss structure, and the length of each beam is generally less than 12 meters. The main beam of girder launcher machine is connected by a pin shaft so that it has flexible assembly and convenient transportation. Hengyuan Group is an experienced bridge girder erection machine manufacturer, and welcome to contact us at any time if interested.

Features and 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 of 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 and easy installation.
9. A-type fracture surface, continuous girder with low center of gravity, convenient and reliable.

Safety Devices:
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.
