Ship Building Gantry Crane

We offer the world’s most complete range of lifting equipment for shipbuilding, from workshop chain hoists to the Goliath Gantry Crane.

Shipbuilding gantry crane (shipyard gantry crane) is crane machinery with large hoisting capacity, multiple functions and high efficiency,dedicated to subsection transport of large ship, butt jointing, and overturning on dock or shipway.

Brief Introduction of Ship Building Gantry Crane

2*25t+50/10t~600t Ship Building Gantry Crane

Lifting the shipbuilding process

Dafang makes ship building cranes and other ship lifting equipment for every stage of the shipbuilding process.

When shipbuilding material arrives by ship or barge, then moves the material with small ganty crane and sometimes plate handling cranes. (the first crane to handle it is an unloading crane.) From pre-treatment, it continues into the workshop. Steel plates brought into the cutting area by light overhead cranes. As the welding of plates creates bigger segments and ship blocks, each crane gets bigger accordingly. And they need more features and special attachments, as the shipyard cranes increase in size.

Goliath gantry crane

When the ship blocks are moved outside, the Goliath Gantry Crane takes over. Being able to lift and assemble large blocks reduces dry dock time and speeds up the entire shipbuilding process.

When the hull is ready for launch, the dry dock gate is opened. The outfitting quay with jib cranes or floating dock cranescontinue the work from where the dry dock jibs finished.
