Gantry Crane for Shipyard Operations

Our gantry crane for shipyard operations is a heavy-duty lifting system tailored for the full lifecycle of ship construction and maintenance, from steel plate handling and hull section assembly to engine module hoisting and offshore component transfer. Unlike standard industrial gantry cranes, it features an optimized structure to adapt to the unique challenges of shipyard work—including large span requirements, uneven load distribution, frequent outdoor operations, and resistance to salt spray, humidity, and extreme temperature changes. Available in single-girder and double-girder designs, with lifting capacities ranging from 100 tons to 2500 tons and spans from 40 meters to 230 meters, it can be fully customized to match the specific layout and operational needs of any shipyard, whether for small-scale repair yards or large-scale shipbuilding bases producing LNG carriers, container ships, and bulk carriers.

Core Features & Technical Advantages

1. Robust Structural Design for Maximum Stability

The crane adopts a high-strength steel frame (Q345B grade steel as standard) with hot-dip galvanizing and marine-grade protective paint, ensuring excellent corrosion resistance and durability in harsh coastal environments. The gantry structure is available in rigid-leg and flexible-leg configurations: the rigid leg provides firm support for heavy loads, while the flexible leg (connected via a hinged joint) adapts to structural deformation, reducing stress on the frame during long-span operations. For spans exceeding 100 meters, the single-girder design is optimized to reduce steel usage and overall weight, minimizing foundation construction costs while maintaining the same load-bearing performance; double-girder designs are preferred for ultra-heavy loads, offering superior rigidity and stability with deflection controlled within 1/800 of the span under full load.

2. High-Precision Control & Multi-Functional Lifting Capabilities

Equipped with advanced variable frequency drive (VFD) systems and PLC-based automation, the crane ensures smooth starts and stops, eliminating sudden shocks that could damage delicate ship components. Anti-sway technology reduces load swing by up to 70%, enabling precise positioning of hull sections, engine modules, and other heavy parts during assembly—critical for ensuring welding accuracy and structural integrity. The crane supports multiple lifting modes, including single-hook lifting, dual-hook tandem lifting, three-hook coordinated lifting, and mid-air hull section turning, allowing for flexible handling of complex operations such as section flipping and precise alignment during block assembly. Upper and lower trolleys (running on independent tracks) can pass each other, enabling air turning of large hull blocks with exceptional precision, while hook traversing screw machinery provides up to 8 meters of hook movement and 100% load unbalance capacity for enhanced flexibility.

3. Comprehensive Safety Systems

Safety is paramount in shipyard operations, and our gantry crane is equipped with a full suite of safety features to protect operators, equipment, and valuable ship components. Standard safety devices include overload protection, lifting height limiters, traveling limit switches, buffer devices, and gantry anti-collision systems. To withstand extreme weather conditions, the crane is fitted with storm locking pins, rail clamps, and tie-downs, ensuring stability during strong winds and harsh weather. The premium operator cabin—accessible via an elevator in the crane leg—features excellent visibility (enhanced by video cameras) and an optimized layout, reducing operator fatigue and improving operational safety. Additionally, redundant skew measurement and maintenance-free hinge and skew control systems prevent dangerous skew events, a major risk for large gantry cranes.

4. Customization & Energy Efficiency

We understand that every shipyard has unique operational requirements, which is why our gantry crane for shipyard operations offers extensive customization options. From lifting capacity, span, and lifting height to electrical components (Siemens, Schneider, ABB), motor brands, and control methods (wireless remote control or cabinet control), every aspect can be tailored to match your specific needs. The crane’s core lifting components—gears, motors, and controls—are purpose-designed and in-house manufactured, ensuring optimal eco-efficiency and reliability, while reducing energy consumption and long-term maintenance costs. The open gear and pinion hoisting design, combined with optimized hoisting speeds, further enhances operational efficiency and extends the crane’s service life.

Applications in Shipyard Operations

Our gantry crane is designed to cover all key stages of shipyard operations, making it a versatile solution for both new ship construction and ship repair:

• ◆ Steel Processing & Material Handling: Transporting and positioning steel plates, profiles, and prefabricated components in workshops and outdoor yards, supporting the initial stages of ship construction.
• ◆ Hull Block Assembly: Lifting and precisely aligning large hull blocks (up to thousands of tons) for welding and assembly, the most critical stage of shipbuilding that requires high stability and precision.
• ◆ Engine & Equipment Installation: Hoisting heavy ship engines, generators, boilers, propellers, and upper structure modules to their designated positions during outfitting operations.
• ◆ Ship Repair & Maintenance: Lifting damaged hull sections, propellers, and other components for repair or replacement, supporting dry dock operations and offshore maintenance tasks.
• ◆ Launching Assistance: Assisting in the transfer of ships to water, supporting ship transfer trolleys or floating platforms during the launching process.
