Gantry crane for subway construction

This type of crane is a special gantry crane developed by our company according to the use requirements and process conditions of subway construction, combined with the general gantry crane, which is specially used for overturning mud and lifting segments during subway construction.

The crane is composed of gantry, trolley (equipped with lifting mechanism, trolley running mechanism and hydraulic overturning mechanism), cart running mechanism, cab and electrical equipment.

According to the different dumping directions, the outrigger structure can be divided into two types: A type and U type.

The crane traveling mechanism adopts 8-wheel 4-drive mode and is equipped with a windproof rail clamp. When the crane works normally, the clamp of the rail clamp leaves the rail. When the crane stops working, the operator puts down the clamp to clamp the rail to prevent the crane from sliding.
