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.

CATEGORY COMPARISON TABLE

Type	Structure	Bridge Type	Span Range	Lifting Capacity	Advantages	Limitations
Single-Girder Launching Gantry	One main girder	Short to medium girder bridges	≤ 30m	≤ 200 tons	Lower cost, simple setup, suitable for light-duty jobs	Limited capacity and stability
Double-Girder Launching Gantry	Two main girders	Highway, HSR, urban viaducts	20m – 60m	Up to 900 tons	High strength, widely applicable, supports heavy loads	Requires more assembly space and time
Segmental Launching Gantry	Multiple articulated girders	Long-span, curved, elevated bridges	30m – 55m	100 – 500 tons	Precision placement, match-cast friendly, good for cantilever methods	Higher technical complexity, costlier
Beam Launcher	Box or truss-type	Straight-span bridges	≤ 40m	200 – 600 tons	Efficient for placing precast beams quickly	Not suitable for curved or segmented bridges
Movable Scaffolding System (MSS)	In-situ cast support	High-speed rail, urban viaducts	20m – 50m	N/A (in-situ cast)	No need for heavy lifting, continuous casting supported	Limited reuse, longer cycle time
