The subway gantry crane is a crane specially designed and manufactured for subway and railway construction. It is usually a double girder gantry crane.

This special gantry crane is mainly used for subway and tunnel construction. Its main function is to carry out the handling of slag and on-site construction materials, and it transfers the slag excavated by the shield excavator to the ground.

With the span-changed function of Min. step-length 100mm, this subway construction gantry crane is suitable for various working conditions. Its cantilever can be disassembled or retained. The cantilever interface is very flexible under different working conditions.

It has a lightning protection system and a wind speed detection and early warning system, which greatly guarantees the safety of the gantry crane. This special gantry crane is also equipped with a special spreader that enables the interchange of slag buckets and hooks. It can be flipped anywhere in the air using a flip structure.

The residue system is hydraulically controlled, which makes the turning process more stable, and its trolley is also rotatable, allowing the front and side to transport the residue.

With the rapid economic development and serious traffic problems in many cities, subway construction is also in rapid development.
