Typically, precast segmental bridges and precast girders are placed using ground-based cranes to lift each segment or girder. However, ground access to the spans may be challenged by the presence of existing infrastructure or bodies of water, or the height to which the segments must be raised can exceed the reach of ground-based cranes. A launching gantry can be used to solve these issues.
