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

Yuantai shipyard gantry cranes are built to handle heavy-duty lifting in harsh marine environments while keeping daily operation smooth and reliable. After reviewing the key features below, you will better understand how these cranes help you lift larger loads, work more safely, and improve productivity in busy shipyards.

1. Dual-Girder Structural Design

The double-box girder structure gives you strong stability when lifting uneven or off-center loads. It follows ISO 4301 standards and keeps deflection within 1/800 of the span under full load, which protects both your load and the crane structure. This design helps reduce vibration and improves overall lifting safety. It also helps in the smooth running of the crane which also helps in prolonging the life of the crane.

2. Corrosion-Resistant Materials

The crane uses high-grade Q345B steel combined with hot-dip galvanizing of at least 80μm and marine-grade protective paint. This material system helps the crane resist salt spray, humidity, and rapid temperature changes commonly found in coastal shipyards. You get better protection against rust and surface damage, which lowers your long-term maintenance requirements. This construction ensures the crane stays reliable even after years of outdoor use.

3. Precision Control Systems

The Variable Frequency Drive system gives you smooth starts and stops, helping you control heavy loads without sudden shocks. Anti-sway technology can cut load swing by up to 70%, which improves positioning accuracy and reduces the risk of accidents. PLC-based automation and remote diagnostics allow you to detect faults early and plan maintenance before serious failures occur. This level of control helps you work faster while keeping your operators and equipment safer.

4. Multi-Function Capabilities

These cranes support single lifting, hoisting, in-air turnover, and slight horizontal turnover, which makes them suitable for many shipbuilding and repair tasks. You can handle complex lifting sequences without needing multiple machines. This improves workflow efficiency and reduces downtime between operations. It also helps you complete heavy assembly work with greater control and fewer handling risks.

5. Upper and Lower Trolley Design

The upper trolley uses two main hooks mounted on the outside of the girder, which helps you balance and stabilize large loads. The lower trolley includes one main hook and one secondary hook positioned at the center of the girders for more precise lifting tasks. Both trolleys can operate crosswise, allowing you to coordinate complex lifts. This setup gives you more control when handling oversized or irregularly shaped components.

6. Full Frequency Control

All operating mechanisms use full frequency control to provide smooth and precise movements. You can accurately adjust lifting, traveling, and positioning speeds based on the load and work conditions. This reduces mechanical stress on the crane and improves operator comfort. Over time, this control system helps extend the life of key components.

7. Wind Protection

Reliable anti-wind devices, including rail clamps and ground anchors, keep the crane stable during strong winds and storms. These safety systems help prevent unwanted movement and structural damage when weather conditions change quickly. You gain better protection for both the crane and surrounding equipment. This feature is especially important for coastal and open-yard operations where wind loads can be severe.

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.
