Shipbuilding gantry crane is a special lifting equipment that works on the dock, berth or platform of the shipyard to lift and turn over the hull segment.

Due to the large span of the shipbuilding gantry crane, the gantry usually adopts the type of rigid leg on one side and flexible leg on the other side, that is, the rigid leg on one side is firmly connected with the main beam, and the flexible leg on the other side is connected with the main beam through the flexible hinge.
There are two kinds of main beams: single main beam and double main beam. According to the requirements of shipbuilding process, shipbuilding gantry crane should have a variety of functions, such as single lifting, double hook lifting, three hook lifting, hull section turning over in the air and air micro-rotation, especially to meet the requirements of hull section turning and closing operations. Shipbuilding door machine is generally set up two cars. The upper and lower cars respectively travel on their own tracks, and the lower car can travel under the upper car.

1. Large lifting weight, large span and high lifting height.

2, with single lifting, double hook lifting, three hook lifting, hull segment air turn over and air micro rotation and other functions;
3, set up two cars. The upper and lower cars respectively travel on their own tracks, and the lower car can travel under the upper car.
4, with a transverse mechanism, can be moved separately to complete the workpiece micro-movement and micro rotation, in the closing can be accurate alignment.
5, with the upper correction device and the lower correction device two sets of correction devices, to prevent the truck running deviation operation. Ensure safe operation of the crane.
