Feeding beam by transportation trolley or vessel( two way: under the bridge or at the end of the bridge), segmental launching gantry picks up each segmental beam and hangs on the main beam; accurate registration, applying glue, and forming the whole beam. Then segmental launching gantry will place the finished beam on the bridge pier and connect it with adjacent bridge through wet joint. Single span erection is completed. Segmental launching gantry moves across and continue the next segmental beam construction.
