The gantry crane for shield uses a special spreader, and the spreader can be rotated 360 degrees. Suitable for installation of different angles of the cutter head. The utility model adopts a double trolley structure, and the two trolleys can be linked together to lift the cutter cutter disc, and the lift pipe can also be separately operated. When there is a large lifting tonnage, the lifting adopts open gear transmission, which reduces the cost of equipment.
