Shipyard Portal Crane

Shipyard use Ship Building Gantry Crane with  double Parallel Trolley

what is Shipbuilding gantry crane ?

Double Girder Shipbuilding Gantry Crane is a kind of great lifting capacity, large span, high lifting altitude, multi function, high efficiency of gantry crane, is special for the fragmented transport, end-to-end joint and turning operation of large ship hulls. MU shipbuilding gantry crane is used in the place of manufacturing of ship and dock.

Compared with the traditional portal crane, large shipbuilding gantry crane has the obvious advantage of the installation and transportation of hull sections. It spans the dock (berth), can provide on-site assembly service at the coverage plane in the dock, not only has the lifting, horizontal transport function, but also can implement hull air turnover, adjusting the fragment to the welding position of ship required.

whats the technical characteristics part of Shipbuilding gantry crane ?

1. It have multiple functions of single hanging, hoisting, turnover in the air, slight horizontal turnover in the air and so on;

2. The gantry falls into two categories: single girder and double girder. To rationally utilize materials, the girder adopts optimum design of variable section;

3. The gantry rigid legs with a single column and double column type for customer choice.

4. The upper trolley has two main hooks, which are separately fixed at both sides of the main beam, but the lateral movement can be individually or simultaneously 0 - 2m.

5. The lower trolley has a main hook and auxiliary hook, which fixed below at the center of the two girders;

6. Both the upper trolley and the lower trolley can cross each other for operation;

7. All the lifting mechanism and travelling mechanism adopts frequency conversion speed regulating;

8, On the top of the girder at the side of rigid leg is equipped a jib crane to accomplish maintenance of upper and lower trolley;

9. In order to prevent the storm attack, such safe and reliable anti-wind devices as rail clamp and ground anchor are equipped.

whats the Safety Devices of Shipbuilding gantry crane ?
