Double Girder Gantry Crane for Shipbuilding is one kind of gantry crane, it main used to berth assembled hull. This kind of shipbuilding crane has the feature of load and unload, lifting, segmented turning the air. Have the advantage on turning the hull and close operations. The first is through the upward and downward adjustments, the entire segment by car to bear on.

 

Ship gantry crane used in the place of ship manufacture and the dock, its task is to put all the parts required for the manufacture of the ship (ribs, steel and etc.) from the ground transportation to manufacturing place. This transport work must be able to complete the task in a very long journey in transportation quickly. Therefore, the number of cranes decided, enough to reach the dock area of the entire foundation, and each crane mutually interfere with each other in principle.

 

Main feature of the crane

Crane metal structure main contains the main beam, rigid legs, flexible legs, ground beam and railing, cab etc.

Crane main beam adopts double beam structure, on the panel of the two main beam, there are 4 rails which is used for trolley traveling. One set crane has two main hook, running on a track on the bridge flange, in order to turn and lifting large hull blocks.

In order to light the dead weight, rigid legs adopt box type; flexible legs adopt herringbone frame structure, composed by the joint, two pipes, under the joint.

Crane power supply adopt cable drum. Trolley adopt suspension cable pulley device, set on the top surface of the two main beams.

Double girder shipbuilding goliath crane has overload protection, windproof rail clamp, limit anchoring device, wind speed various institutions, load display device.
