Segment Launching Gantry SLG 120

Melbourne, Australia

Segment launching gantry to lift and launch precast elements used for the construction of the new elevated road above the Footscray Road in Melbourne.

17 hanger beam trolleys are installed on the top of the upper chords. Each trolley is fitted with two spreaders and each spreader beam is fitted with two twist-locks which are operated directly by the trolley and hook the segment lifted by the main trolley.
