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.
High Lifting Capacity: Shipbuilding gantry cranes can support lifting capacities ranging from 100 tons to over 1500 tons, depending on the specific model and design. Common configurations include dual trolleys with capacities like 2×50+100 tons or 2×400+400 tons.
Large Span: The span of these cranes can reach from 50 meters to 185 meters, allowing them to cover extensive areas of the shipyard and accommodate large hull sections.
Adjustable Lifting Height: The lifting height typically ranges from 28 to 76 meters, enabling the crane to handle tall structures and facilitate various assembly processes.
Multiple Functions: These cranes are designed for a variety of operations, including hoisting, transporting, flipping, and closing ship bodies. They can perform single hanging, turnover, and slight horizontal movements in the air.
| Parameter | Value |
|---|---|
| Lifting Capacity | 100 to 1500 tons |
| Span | 50 to 185 meters |
| Lifting Height | 28 to 76 meters |
| Speed | Up to 0.5 m/min |
| Configuration | Single girder or double girder |
Hull Assembly: Used extensively for assembling hull sections, allowing for efficient construction processes.
Transporting Large Components: Facilitates the movement of heavy components within the shipyard, including engines and other machinery.
Flipping and Closing Operations: Essential for turning over large hulls and closing them during the final assembly stages.
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.
Yes, because the working condition are different, all our products are customized depending on detail requirement! So all your products will be specially designed by our engineers according to your workshop conditions.
Yes, all kinds of certification are available, if you have doubt, you can come to our factory and test it by yourself,or you can let some third-partied to do the inspection for you.
