Shipbuilding Gantry Crane
Shipbuilding Gantry Crane Brief introduction
This kind of gantry crane is special for the fragmented transport, end-to-end joint and turning operation of large ship hulls. ME 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), and 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.
Shipbuilding Gantry Crane Features
Shipbuilding Gantry Cranes have multiple functions of single hanging, hoisting, turnover in the air, slight horizontal turnover in the air and so on;
The gantry falls into two categories: single girder and double girder. To rationally utilize materials, the girder adopts optimum design of variable section;
The gantry rigid legs with a single column and double column type for customer choice.
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.
The lower trolley has a main hook and auxiliary hook, which fixed below at the center of the two girders;
Both the upper trolley and the lower trolley can cross each other for operation; All the lifting mechanism and traveling mechanism adopts frequency conversion speed regulating;
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;
In order to prevent the storm attack, such safe and reliable anti-wind devices as rail clamp and ground anchor are equipped.
