Basic definition and use:
Segmental Girder launcher (launching gantry) is a special gantry crane used in bridge construction, The principle of the segmental prefabricated assembly construction technology is to divide the bridge superstructure into a number of standard segments. After matching the prefabrication at the prefabrication site, special assembly equipment such as a LG is used on site to build the bridge substructure in sequence. The segments are assembled and prestressed at the same time to make it an integral structure, which is advanced and assembled span by span along the predetermined installation direction.
Applicable bridge types:
Continuous beam bridge, rigid frame bridge, cable-stayed bridge (main beam segment).
Especially suitable for bridges with large spans (more than 40~100 meters) and complex terrain (such as crossing rivers and roads).
Differences from other bridge erection machines
| Comparison item | LG segment assembly bridge erection machine | Traditional bridge erection machine (whole span erection) |
| Construction object | Small prefabricated segment | Whole span prefabricated beam (such as 30m box beam) |
| Applicable span | Large span (flexible segmentation) | Small and medium span (standard span) |
| Precision requirement | Extremely high (millimeter-level splicing) | Relatively low (centimeter-level support positioning) |
| Terrain adaptability | Strong (no need for large beam transport channel) | Depends on flat transportation route |
