Shipbuilding gantry cranes are specifically used for shipyard for building, assembling and maintaining ships, and they can perform segmented hoisting and turning operations of the hull. Shipyard cranes are mainly composed of the main beam, rigid and flexible legs, crossbeam, hoisting mechanism, travelling trolley. They move along tracks or rails, allowing them to pass through large shipyards.
To meet the requirements of precise hoisting operations, the lifting and travelling mechanisms of shipbuilding gantry cranes usually adopt variable frequency speed regulation technology to achieve smooth speed control.
As shipbuilding gantry cranes usually operate in an open-air environment and are vulnerable to strong winds, they are fitted with reliable wind protection devices, such as rail clamps, ground anchors, and anchor chains to prevent movement or tipping when not in use.

You should provide the following information:
-Capacity
-Lifting height
-Span
-Travelling length
Different technical requirements make prices different.
Normally, it will take 60 working days after receiving the prepayment.
It depends on the site situation, such as how many workers will attend to the installation work? How many hours the site workers work per day? Under normal circumstances, 20 days is okay for finishing one set installation.
All the crane spare parts are guaranteed for 12months from the B/L date.
Yes, if you have need, we will arrange engineers to the installation site to guide the assembly work.
The crane will be packed in containers and transported by sea.
Yes, we will regularly conduct online diagnoses for our customers and provide maintenance guidance. If there are any offline maintenance needs, we will send engineers to carry out the maintenance task.
Factory installation and commissioning, during the process, a series of performance tests are carried out, including those on lifting, rotation, heavy load, travel, and safety devices. Through these tests, we meticulously examine various performance indicators to make sure that they all meet the relevant standards.
Single-girder shipbuilding gantry crane has only one main girder, a relatively simple structure, and a low load-bearing capacity, suitable for some auxiliary operation areas in small and medium shipyards.
Double-girder shipbuilding gantry cranes usually has a stronger load-bearing capacity and can meet the lifting requirements of large shipbuilding and equipment, used in the main dry docks, docks and other areas of large shipyards.
The maintenance and upkeep of machines are very necessary. You need to conduct in-depth research on the maintenance manual, which is tailor-made according to the specifications of each machine.
It’s maintenance mainly includes the main beam and legs, hoisting mechanism, luffing mechanism, traveling mechanism, electrical system maintenance, safety devices, lubrication work, daily inspection and regular maintenance.
