Gantry Crane with Sheild(DMG) is mainly used for installation of cutter and shield machine, which underground trenchless device, and used for lifting of ductpiece supporting tunnel druing working progress. DMG has stable performance, high production efficiency and is easy to be repaired and maintained. The lifting appliance at uupper part can turn to adapt the requirements of tunneling at different directions. It has flexible operation method, complete saftey indication and overload protection on device, which can ensure the safety of operator and equipments. Electrical panel adopts PLC variable frequency controller to regulate.
