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.

Features:
It 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.
