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. Features of subway slag gantry crane:

◆ variable span, improve crane utilization;

◆ cantilever detachable, more practical;

◆ running fast, high work duty, high efficiency;

◆ high lifting height;

◆ with special tilting spreader with automatically tipping.

1. The gantry crane for subway construction is used for dealing the dregs and site material handling during subway construction.

2. With the span-changed function of Min. step-length 100mm, this subway construction gantry crane is suitable for various working conditions.

3. The cantilever is detachable, also can preserve the cantilever interface which will be flexible for different working conditions.

4. There is lightning protection system, wind speed detection warning system.

5. The gantry crane for subway construction is equipped special spreader and realize the interchange of dregs bucket and the hook.

6. With 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.

7. The trolley is rotatable, and can realize the front, side transporting dregs.
