Bridge Girder Erection Machine (Gantry Crane Launching)
Bridge Girder Erection Machine (Gantry Crane Launching)
Precision Engineering for Modern Bridge Construction – Trusted by Global Infrastructure Leaders
The Bridge Girder Erection Machine, also known as a Launching Gantry Crane, is a critical piece of equipment in segmental bridge construction. Designed to lift, align, and place precast bridge girders or segments with precision, it plays a vital role in ensuring project speed, safety and structural accuracy.
At Henan Mine, we combine robust engineering, customizable configurations, and field-proven experience to deliver high-performance launching gantries for high-speed rail, highway overpasses, metro viaducts, and long-span bridge projects. Our bridge launchers are used by top infrastructure contractors in Asia, the Middle East, Europe and Latin America.
