China's First Launching Gantry for Prefabricated Structure Assembly Successfully Rolls Off the Production Line

On August 2, China's first launching gantry for prefabricated structure assembly rolled off the production line in East China's Jiangsu province.

Developed by China Railway Science & Industry Group Co., Ltd and China Railway Construction Engineering Group, the launching gantry is planned to be used for the construction of a metro line in Guangzhou.

Equipped with 72 sensors and 50 cameras, the launching gantry is 80 meters long, with a weight of 460 tons and an effective span of 69 meters. It can install beams weighing up to 120 tons.

A total of eight independently movable legs consisting of 32 tires allow the launching gantry to walk more flexibly and cross obstacles.

Adopting Beidou positioning technology, the launching gantry has a measurement accuracy of 10 millimeters, and has applied for two national invention patents, said one of the researchers.
