Highway Bridge Launching Crane Viaduct Girder Launching Machine
Segmental erecting bridge erecting machine is mostly used for erection of box girders of large-span highway bridges, which can meet the needs of bridges: uphill, downhill and skew installation, ensuring bridge installation quality and safe construction. The bridge erecting machine can complete...
Description
The Beam Launching gantry combines a variety of functions, outstanding performance, convenient operation and safety structure into a perfect whole.It has a steel structure of rail type prefabricated beam crane frame equipment.The product can not only be used in plain construction, but also meet the construction requirements of highway slopes, small radius curved Bridges, inclined Bridges and tunnel Bridges in mountainous areas.
The beam launching gantry consists of the main girder, the crane, the front leg, the back leg, the front leg cylinder, the back leg cylinder and the transverse connections of the front, middle and back legs.The control part is composed of hydraulic system and electrical control system.The characteristics of the bridge erecting machine are reasonable and compact structure, easy to install, the main standard beam using pin connection.The double beam structure is connected between the two frame beams by welded tubes.
Beam launching gantry can not only meet the standard setting, but also meet the requirements of cross curve erection, variable span erection, cross continuous beam, composite beam, continuous steel, etc.With good stability, high efficiency, safe and reliable, variable distance convenient, easy to adjust, easy to operate and so on.
Segmental launch gantry is usually used for installation of road and subway Bridges with small spans and prefabricated and prestressed concrete box girders (PC box girders).The main characteristic is the construction efficiency is high, can move by oneself.It is generally composed of main girder, supporting leg, lifting trolley, etc.The main beam is used for supporting and supporting the horizontal movement, vertical movement, horizontal movement, support, crossing and lateral movement of the whole machine.The crane is used to lift the beam.
