Huada Heavy Industry from 2008 to began product and design segment launching gantry, for segment launching gantry bridge construction sequence requirements are very strict.

Segment Launching Gantry Bridge Construction Main Sequence:
Precast segment girders are made while the substructure is being built and then stored until needed for erection.
Advancing the erection girder into place to erect the adjacent span. Launching girders are built out from the abutments of the piers.
There is one cycle of stressing and grouting of tendons per span, which requires one cycle per pair of segments.

Segment Launching gantry, generally self-launching, usually adopted to launch an entire precast girder, and economically viable for a relatively long stretch of viaduct construction.
