Gantry crane with shield (DMG for short) is mainly used for installation of cutter and shield of shield machine which is underground trenchless device, and used for lifting of ductpiece supporting tunnel during work progress. DMG has stable performance, high production effieciency and is easy to be taken care of and maintained. The lifting appliance at upper part can turn to adapt the requirements of tunneling at different direction. It has flexible operating mode, complete safety in dication and overload protection device, which can uttermost ensure the safety of operator and equipments. Electrical system adopts PLC variable frequency speed regulating which is ProPitious to control the mechanisms. Famous manufacturer of fittings is adopted to guarantee the quality of the complete machinhe latest issured national standards are executed for design, manufacture and inspection of DMG.
