Shipbuilding Gantry Cranes for Shipyards

Shipbuilding gantry cranes are perfect for moving large ship components such as hulls, engines and more. Our cranes are perfect for shipbuilding or ship repair and can handle thousands of tons. Whether you need to build a new ship or repair an existing one, this crane can meet your requirements.

Key Features of Yuantai Shipyard Gantry Cranes

• Adaptable Load Capacity: Cranes are available in configurations ranging from 50 to 1,000 tons, suitable for lifting everything from small vessel parts to massive ship blocks. Modular design allows adjustments based on project requirements.
• Dual-Girder Structural Design: Features a double-box girder framework for stability when handling unbalanced loads. Complies with ISO 4301 standards, minimizing deflection (≤1/800 of the span) under full load.
• Corrosion-Resistant Materials: Constructed with high-grade steel (Q345B), hot-dip galvanized (≥80μm coating), and marine-grade paint to withstand saltwater exposure, humidity, and temperature fluctuations in shipyard environments.
• Precision Control Systems:
  • Equipped with Variable Frequency Drive (VFD) for smooth acceleration and deceleration.
  • Anti-sway technology reduces load swing by up to 70%.
  • Remote diagnostics and PLC-based automation for error detection.
• Mobility and Flexibility:
  • Rail-mounted systems with a standard gauge of 10–50 meters.
  • Optional rubber-tired configuration for yards without fixed rails.
• Multi-Function Capabilities: Supports single lifting, hoisting, in-air turnover, slight horizontal turnover, and more.
• Optimized Gantry Design: Gantry comes in single-girder and double-girder types, with variable-section design for efficient material utilization.
• Upper and Lower Trolley Design:
  • Upper trolley features two main hooks fixed on the outside of the girder.
  • Lower trolley includes one main hook and one secondary hook fixed at the center of the girders.
  • Upper and lower trolleys can operate crosswise.
• Full Frequency Control: All operating mechanisms employ frequency control for precise operation.
• Maintenance Accessibility: A jib crane is installed on the girder at the rigid leg side for maintenance of upper and lower trolleys.
• Wind Protection: Equipped with reliable anti-wind devices such as rail clamps and ground anchors to ensure safety during storms.

Optional Accessories

To tailor your crane to specific operational needs, a range of accessories is available. You can enhance lifting capacity, improve control, and reinforce structural safety. Below are some common options and their benefits.

1. Hoist Equipment

Choose from standard electric wire-rope hoists with single- or dual-speed control for versatile lifting speeds. For hazardous environments, an explosion-proof hoist meets ATEX or NEC standards, keeping sparks away from flammable atmospheres. In marine or coastal yards, a marine-grade chain hoist with a motorized trolley offers corrosion-resistant components and smooth travel under heavy loads.

2. Control & Monitoring

Upgrade to a radio remote control with an ergonomic handset for full operator mobility and clearer sightlines. A wired pendant push-button station provides a reliable backup when wireless signals might drop. Add a load moment indicator (LMI) and overload protection system to track the crane’s lifting angles and cut power if you exceed safe limits. Cameras and load-view monitors mount near the hook or spreader, giving operators a clear view of the load path and improving onsite safety.

3. Structural Enhancements

In regions prone to high winds, rail clamps and ground anchors secure the crane to the foundation and prevent drift. A lightning protection and grounding system diverts strikes safely to earth, protecting sensitive electronics. To shield controls and power panels from rain, dust, and UV exposure, weather-proof enclosures with rubber gaskets and corrosion-resistant hardware are available. You can also specify custom paint colors with anti-UV coatings to match your facility’s branding and extend the finish life.

Safety and Compliance

Ensuring crane safety and meeting regulatory standards is central to Yuantai’s design and manufacturing process. Every crane undergoes rigorous quality checks, full-load testing, and non-destructive inspections before it leaves the factory.

1. Certifications and Quality Management

Yuantai operates under an ISO 9001 quality management system that tracks every step—from raw-material sourcing to final assembly. We hold CE marking for the European market, along with TUV and SGS approvals for mechanical integrity and material traceability. Before shipment, each crane completes a full-load test at 125 % of rated capacity, plus NDT (magnetic particle or ultrasonic) on welds and critical castings. Test reports and certificates ship with the equipment, ready for your audit files.

2. Mechanical Safety Devices

All moving axes feature fail-safe limit switches to halt travel at both ends of the trolley runway and hoist path. End-car bumpers absorb impact if the crane overruns its buffer zone, protecting rails and wheel assemblies. To control load swing, anti-sway dampers engage automatically during hoist acceleration and deceleration. These mechanical safeguards work without operator input, reducing the risk of collisions and material damage.

3. Electrical Protection Systems

Integrated overload relays monitor motor current and drop out power if the load pulls more than 110 % of rated torque. Phase-loss detection guards three-phase motors against single-phasing, which can overheat windings. Variable-frequency drives (VFDs) and control cabinets include surge suppressors to shield sensitive electronics from voltage spikes. An earth-fault monitoring circuit continually checks grounding integrity and triggers an alarm if resistance exceeds safety thresholds.
