{{/usCountry}}What is LG installation?
Launching girder (popularly mentioned as LG), also known as launching gantry, is used to lift and support bridge segments or girders as they are placed while being supported by the bridge piers instead of the ground. A launching girder is in general a design-and-built machine used in precast post-tensioned bridge construction. It consists of lifting devices and a supporting structure for lifting precast beams and precast bridge segments in position for assembling.
