Bridge Construction Machine 100-200Tons

The Beam Launcher can drive itself into the bridge position under no load condition, then straighten the front column and support it on the front pier. When the beam (or the whole beam) moves along the boom, the boom is close to the simply supported beam. When the bridge is bridged, the machine can move into the bridge position on its own in the empty state. First, the beam must be transferred from a special gantry crane to a special beam truck, then the rear end of the girder car and the bridge erecting machine is countered, and the beam is hoisted with two hanging beams on the crane arm of the bridge erecting machine, along the crane arm, to the bridge position.

Bridge Girder Launching Crane, One of the bridge construction machinery, its boom is a box girder, which is hung forward, and there is a collapsible column at the front end.


The Beam Launcher can drive itself into the bridge position under no load condition, then straighten the front column and support it on the front pier. When the beam (or the whole beam) moves along the boom, the boom is close to the simply supported beam. When the bridge is bridged, the machine can move into the bridge position on its own in the empty state. First, the beam must be transferred from a special gantry crane to a special beam truck, then the rear end of the girder car and the bridge erecting machine is countered, and the beam is hoisted with two hanging beams on the crane arm of the bridge erecting machine, along the crane arm, to the bridge position. Beam.


The main structure of the bridge erecting machine consists of the main beam, the upper cross beam and the front frame, the hoisting crane, the supporting and transecting wheel group, the track system, the supporting wheel mechanism, the front hydraulic top lifting mechanism, the rear driving device, the transport beam flat car, the electrical system and so on.


1) the main beam: the "A" section is used, and the pin shaft connection is assembled according to the number.


2) hoisting crane: a total of 2 units, lifting mechanism is composed of equipped winch and pulley block and spreader. The concrete beam is lifted to complete the longitudinal and lateral operation of the concrete beam and to control the installation of the concrete beam.


3) front and rear supporting wheel group and track system: adjust the passing direction of bridge erection machine by supporting lateral moving wheel set to meet the requirement of curved bridge.


4) the supporting wheel mechanism: to realize the longitudinal movement of the main girder of the bridge erector.


5) rear drive device: both rear support and rear drive.


6) beam transport: equipped with 2 flat cars for transporting beams, and the speed of operation is controlled by variable frequency speed regulation.


7) electrical system: the power source of various agencies, and the main circuit and control loop can run safely through all kinds of corresponding protection.



The Bridge Erection Machine 150T/40M is used in Gorontalo for Bridge Construction in Indonesia in the 2017year.  Here are the Producing and Installation on site photos for your reference.
