Because the subway is comfortable, fast and convenient, it is becoming an important parts of transport in many urban cities.

With the fast development of subways, the construction machines, especially the cranes, are becoming an important role for the subway construction. Flag Crane has rich experience and many project cases on subway construction gantry crane.

Subway gantry crane for slag handling is used for subway tunnel construction. This crane is mainly responsible for the construction of the subway tunnel, lifting the dregs excavated by shield excavator to the ground.

• 1Variable span, improve crane utilization;
• 2Running fast, high work duty, high efficiency;
• 3High lifting height;
• 4With special tilting spreader with automatically tipping.
• 5With the span-changed function of Min. step-length 100mm, this subway construction gantry crane is suitable for various working conditions.
• 6The cantilever is detachable, also can preserve the cantilever interface which will be flexible for different working conditions.
• 7There is lightning protection system, wind speed detection warning system.
• 8The gantry crane for subway construction is equipped special spreader and realize the interchange of dregs bucket and the hook.
• 9With the overturn hook, it realizes overturning the dregs at any position in the air. Overturning dregs system is controlled by the hydraulic which makes the overturning process more stable.
• 10The trolley is rotatable, and can realize the front, side transporting dregs.
