Advantages of Gantry Crane for Shield Tunneling Machine:
Gantry Crane for Shield Tunneling Machine is mainly used for the installation of the cutter head and shield body of the shield machine of the underground trenchless equipment, as well as the hoisting and transportation of the tunnel support segment during the construction process; the special sling is used, and the sling can be 360°. Rotating, suitable for the installation of different angles of the cutter head; adopting the double trolley structure, the two trolleys can be linked together to lift the cutter head, and can also work independently to lift the segment. When there is a larger hoisting tonnage, the hoisting adopts open gear transmission, which reduces the equipment cost.
The working system of Gantry Crane for Shield Tunneling Machine is A4, and the recommended rails are QU80-QU100. The lifting capacity is 200-400 tons.
