Ship Building Gantry Crane

Product Description:

Ship building 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. Ship building gantry crane is used in the place of manufacturing of ship and dock.
In the past ten years, with the development of large-scale ship building, Shipyard gantry crane for sale, ship building gantry crane is the rapid growth of demand. Compared with the traditional portal crane, large ship building 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.

Features:

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.
