Wind power installation crane

This product is an ultra-heavy-duty intelligent engineering crane specifically designed for onshore wind turbine installation, integrating three core capabilities: extremely high working altitude, precise wind-resistant load stabilization, and rapid self-assembly/disassembly. It overcomes the challenges of installing large-tonnage components (nacelles, blades, hubs) at heights over 100 meters, enabling a single crane to cover the full range of 3.X–15MW wind turbines, significantly reducing wind farm construction costs and timelines.

In the field of onshore wind farm construction, the hoisting process has always been the key factor determining project success and efficiency. As turbine power continues to increase (3.X–15MW), critical components such as nacelles, blades, and hubs are not only heavier but also installed at heights commonly exceeding 100 meters. This presents nearly extreme demands on traditional lifting equipment. To address this industry pain point, we introduce the ultra-heavy-duty intelligent engineering crane specifically designed for onshore wind turbine installation, integrating three revolutionary capabilities and setting a new benchmark for wind farm construction.

Core Capability 1: Ultra-High Working Altitude Beyond Limits

• Challenge: Modern high-power turbine hub heights commonly exceed 120 meters and can reach over 160 meters. Traditional crawler or all-terrain cranes often struggle with lift height and boom configuration, requiring multiple cranes or auxiliary structures, greatly increasing cost and risk.
• Solution: This crane achieves an effective working height of over 160 meters through an innovative ultra-long truss boom/jib combination design, application of high-strength lightweight materials, and precision hydraulic telescoping and luffing systems. Its robust structural rigidity and stability ensure safe and reliable heavy-lift operations even at maximum heights.
• Value: A single unit can meet the hub height requirements of most modern onshore turbines, completely eliminating dependence on ultra-high auxiliary towers or tandem lifting.

Core Capability 2: Precise Wind Resistance and Load Stabilization for High-Altitude Safety

• Challenge: Wind speeds at high altitudes are unpredictable. Particularly for components like blades with large wind-exposed areas, wind loads can cause significant load swinging, positioning difficulties, and even safety incidents. Traditional cranes rely on operator experience and basic anemometers, lacking precision and responsiveness.
• Solution: This crane integrates a multi-dimensional intelligent load stabilization system:
  • Real-time wind field sensing network: High-precision wind speed and direction sensors are installed at key boom positions and on the hook.
  • Active anti-sway control: Based on sensor data and dynamic load models, the control system calculates and applies counter-torque in real time, using hydraulic servo mechanisms to actively suppress load swinging.
  • Micro-motion precision positioning system: Equipped with millimeter-level precision hoisting and slewing control, combined with visual assistance systems (e.g., HD cameras, laser positioning), enabling “thread-the-needle” precision installation of large-tonnage components at heights over 100 meters.
• Value: Significantly improves safety, installation accuracy, and efficiency under high-wind conditions, reducing schedule delays caused by weather.

Core Capability 3: Efficient Self-Assembly, Flexible and Convenient Relocation

• Challenge: Wind farms are typically located in remote areas with complex terrain. Disassembling and transporting large cranes is time-consuming and costly, requiring large auxiliary equipment and skilled crews, becoming a bottleneck for overall project progress.
• Solution: This crane features a modular self-assembly/disassembly design:
  • Integrated self-jacking/self-dismantling system: Uses the crane’s own power and hydraulic systems to automatically assemble and disassemble major components (e.g., counterweights, main boom sections, outriggers).
  • Modular transport units: All components are designed to comply with standard road transport dimensions and weight limits, eliminating the need for special oversize transport permits.
  • Intelligent assembly/disassembly guidance: The integrated control system provides step-by-step guidance and safety monitoring during setup and breakdown.
• Value: Dramatically reduces relocation time (by over 50%), reduces dependence on large auxiliary cranes and complex site conditions, significantly improving equipment utilization and project turnover efficiency.

Full-Series Coverage, Revolutionary Reduction in Cost and Cycle Time

The core value of this crane lies not only in its powerful individual performance but also in its exceptional adaptability:

• Wide power coverage range: Through an intelligent load-moment limiting system, interchangeable counterweight configurations, and optimized boom combinations, a single crane can efficiently and safely install core components for the entire series of onshore wind turbines from 3.X MW to 15 MW.
• Significant comprehensive benefits:
  • Reduced equipment investment: No need to purchase or rent multiple specialized cranes for different turbine power ratings.
  • Shortened construction timeline: High-efficiency single-crane operation, precise installation, and rapid relocation capabilities greatly compress overall wind farm construction time.
  • Lowered total cost: Optimization across equipment purchase/rental, labor, auxiliary measures, and time costs.

Efficiency Comparison Overview: Traditional Lifting Solutions vs. This Product

This ultra-heavy-duty intelligent engineering crane integrates the three core technologies—"ultra-high working altitude," "precise wind-resistant stabilization," and "rapid self-assembly"—to successfully overcome the industry challenge of installing large-tonnage components of high-power onshore wind turbines at great heights. Its ability to cover the entire turbine series with a single unit is not only a demonstration of technical prowess but also a transformation of wind farm construction practices. It provides owners and contractors with a more efficient, safer, and more cost-effective lifting solution, strongly driving the wind power industry toward larger scale, higher efficiency, and lower costs.
