Shipbuilding gantry crane

The shipbuilding gantry crane is a large-scale, heavy-lift gantry crane specifically designed for constructing ships and offshore structures. It features a double-girder bridge supported by two tall legs running on ground rails, with multiple trolleys and hooks for lifting and turning huge hull sections, engine blocks, and prefabricated modules. Lifting capacities typically range from 100t to 1,200t+, with spans over 100m and lift heights exceeding 60m. These cranes operate outdoors in coastal shipyards and are built to withstand harsh marine environments while providing precise, synchronized lifting for complex assembly tasks.

[1] Hull Section Assembly – Lifting and mating prefabricated hull blocks in dry docks.

[2] Engine and Propeller Installation – Hoisting heavy marine engines, shafts, and propellers into position.

[3] Superstructure Fitting – Placing deckhouses, funnels, and masts onto the main hull.

[4] Block Turning – Using dual trolleys to rotate large hull sections for bottom welding.

[5] Launching Assistance – Cooperating with other cranes to slide a completed ship into water.

[1] Ultra-High Capacity – Handles loads from 100t up to 1,200t+, essential for large vessels.

[2] Synchronized Lifting – Multi-trolley system allows precise control for lifting and turning heavy blocks.

[3] Long Span and High Lift – Wide span (>100m) covers entire dry dock; high lift height (>60m) accommodates tall ship sections.

[4] Marine Environment Durability – Corrosion-resistant coatings, sealed electricals, and anti-corrosion steel.

[5] High Duty Cycle – Designed for continuous, heavy-duty shipyard operations (A7-A8 duty class).
