The subway gantry crane is a special gantry crane for lifting and transporting muck in subway tunnel construction. In the construction of subway tunnels, due to the space structure limitation, the excavated time tunnel, it is not for a time before the tunnel. to use a crane to lift the muck from the ground to the ground for processing. The crane has a relatively high level of work and can achieve higher work efficiency.

The main girder of the crane is an off-track box-type structure. The design adopts three-section disassembly and transportation, and through ANSYS finite element data analysis to ensure that the main girder has good rigidity and strength. At the same time, the use of anti-sway control and correction technology to ensure the safe and stable lifting process of the crane, laying a good foundation for the scientific research work of the State Grid.
