A launching gantry (also called beam launcher, girder launcher, bridge building crane, and bridge-building machine, locally nicknamed the "Iron Monster" ) is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects. The launching gantr… WebbPrecast beam launching emitters easily cope with span length and platform geometry changes, planned curvatures and ground restrictions. The beam supports the gantry on the pier and allows lateral movement to erect the side beam and launch along the gantry along the curve.

WebbThe lifting beams of the gantry are always connected to the hoists and are designed for modularity in order to lift I-beams, T-beams and box girders with the same equipment. The twin-truss launchers are relatively inexpensive and easily adaptable in both the length and the spacing of the trusses.
