Discription
A Shipbuilding Gantry Crane is a heavy-duty lifting system specifically designed for the construction, assembly, and maintenance of large ship hulls in shipyards and dry docks. These cranes feature a robust steel structure with either single or double girders, supported by rigid or flexible legs that travel along ground rails. Equipped with multiple hoists (including upper and lower trolleys), they enable precise lifting, positioning, and even aerial flipping of massive ship sections weighing up to 1,500 tons with spans exceeding 185 meters
Why Choose an Shipbuilding Gantry Crane?
● High Load Capacity & Versatility
Designed for heavy-duty operations, handling large ship segments (up to 1,200 tons in tandem lifting) with specialized functions like aerial flipping and micro-rotation
Equipped with dual trolleys (upper and lower) for synchronized lifting, allowing complex maneuvers such as 180° mid-air rotation without manual re-hooking
● Enhanced Stability & Safety
Variable cross-section girders and double-column rigid legs improve structural integrity under extreme loads
Advanced windproof systems (rail clamps, ground anchors) ensure stability in coastal environments
● Automation & Precision Control
PLC-based automation with variable frequency drives enables smooth, millimeter-accurate positioning for welding and assembly tasks
Real-time monitoring (load sensors, anti-sway systems) prevents overload and operational risks
● Customization for Shipbuilding Needs
Configurable as rail-mounted (for fixed docks) or rubber-tired (for flexible movement)
Optional cantilever maintenance cranes and operator elevators enhance accessibility
● Cost & Time Efficiency
Reduces reliance on multiple cranes by consolidating lifting, flipping, and transport into one system
Modular design allows faster assembly compared to traditional setups
