A launching gantry (LG) is a bridge segment lifting machine used for erecting precast segmental bridges and for balancing via the cantilever method or span-by-span method. To meet the site requirement, the LG can be offered as an overhead or underslung model.
Turnaround of LG with a symmetrical system is possible without dismantling and re-erection.
Tower elements below support beams allow adjustments to be made to maintain changes in longitudinal slope.
Sideways movement of the whole system is possible with the extension of support beams for overhead launching gantries.
