Shipyard gantry cranes, also called shipbuilding cranes. The difference from rail mounted container gantry cranes generally shows up in the assembly of ships in shipyards. Rail-mounted gantry crane for shipyard with track. The capacity of these cranes used in shipyards in the gantry crane mode is usually several hundred tons.
Shipyard gantry cranes, which have double lifting machines, are gigantic cranes that reveal themselves from the furthest distance in the shipyard area.
The Shipyard gantry cranes run on the ground track and is a large gantry cranes used for hoisting large welded parts such as shipyards. It is a bridge crane in the shape of a gantry formed by a horizontal bridge set on two legs. Its lifting, trolley operation, and bridge frame are the same as that of a overhead crane.
The rated lifting weight is at least 100t or more, up to 2500t; the span is generally greater than 40m, up to about 230m; the height of the lower cover of the main beam from the ground is between 40m and 100m.

It has a variety of functions such as single hanging, lifting, aerial flipping, and horizontal micro-rotation in the air.
The door frame has two types of single main beam and double main beam for users to choose from. In order to make reasonable use of materials, the main beam adopts a variable cross-section optimized design.
The rigid legs of the gantry are available in single-column and double-column shapes for users to choose from.
The upper and lower trolleys are provided with double main hooks, which are placed on the two outer sides of the main beam, but can be moved laterally by 0-20m individually or at the same time.
The upper and lower trolleys are provided with main and auxiliary hooks, which are placed below the center of the main beam.
The upper and lower cars can cross each other to work.
All lifting mechanisms and operating mechanisms adopt frequency conversion and speed regulation.
On the rigid outrigger side, there is a cantilever crane/hoist gantry crane on the top surface of the main beam for repairing the crane to complete the maintenance operations of the upper and lower trolleys.
In order to facilitate drivers and maintenance personnel to board the plane, there is a boarding elevator in the rigid legs.
In order to prevent storm attacks, it is equipped with safe and reliable rail clamps, ground anchors, anchor chains and other windproof devices.
