Erection Full Beam Launching Gantry Crane 600T Concrete Bridge Launcher Machine
Bridge Girder Erection Machine Introduction
Segment Launching Gantry with the Pre-casting Segment bridge construction method is widely used for both highway and railway bridges. And with the evolution of technology and construction of the situation, the segmental construction of bridges became popular of the hour for almost every bridge and overpass construction around the world.
pre-casting segmental girder are installed as a group along the whole length of span, then prestress is introduced into the structure through external tendons, compared with the balanced cantilever erection method, the span by span method is faster construction and with less workers required.It is designed and fabricated in order to ensure high performances, efficiency, safety, flexibility and multiple successive utilizations.
