Bridge girder erection machine is a new type of walking bridge erecting machine independently researched and developed by our company. The bridge erecting machine is a special railway equipment with a wide operating range, excellent performance, convenient operation and safe structure. The main beam is a truss structure, which has the characteristics of light structure and strong wind resistance. The equipment is mainly composed of main beam, front cantilever, front retreat, auxiliary legs, front and rear cross beams, hoisting mechanism, hydraulic system, electrical control, etc. And it can meet the requirements of large slope, small radius curved bridge, 45 degree slanted bridge and tunnel entrance bridge.

Bridge girder erection machine is used to erect the prestressed concrete girder with span 50m and 51m. The assembly of girder adopts stub matching precast which assembled on site, the girder is put on the piers simply and then combined span by span firmly. The maximum weight of prestressed segment shouldn't exceed 130/140t. The construction method of Bridge girder erection machine is the segmental hanging and then construction tensioning after the steel strands are threaded. 

Bridge girder erection machine Main features and advantages

A. Bridge girder erection machine adopts two-span type; The bearing part of main frame uses box girder structure with good twist resistance; The front and rear guiding girder adopt truss girder structure with light weight. 

B. This machine is equipped with 10t crane which lift some small parts on the bridge in order to construction conveniently. C. The layout of whole machine is parallel, so it can travel reversely. The front and rear legs adopt the same structure which can make the leaping backward come true, in order to improve the efficiency.
