Double Girder Overhead Crane in Wind Power Industry

Product Introduction of the Henan Mine Crane New Double-Girder Crane for Offshore Wind Power

Henan Mine Crane new double-girder crane for offshore wind power is a benchmark premium equipment developed by the company to address heavy-duty lifting demands in offshore wind power and advance the “dual carbon” strategy. Tailor-made for world-class offshore wind projects, the first phase has delivered 43 units successfully installed and operational.

Henan Mine Crane new double-girder bridge crane for offshore wind power This equipment centers on “heavy-load precision, energy-saving lightweight design, safety and intelligence, and suitability for marine conditions.” It effectively addresses industry pain points in lifting heavy offshore wind components (such as nacelles, hubs, and large blades), including “difficult synchronization, excessive sway, high energy consumption, and elevated safety risks.” It provides a one-stop heavy-load lifting solution for world-class offshore wind energy clusters and large-scale wind power equipment manufacturing bases.

Built upon Henan Mine Crane’s “Premium Intelligent Manufacturing” philosophy, this crane integrates dual-trolley design, lightweight energy-saving technology, high-precision synchronous control, and full-lifecycle management. Its core advantages include high lifting capacity, automatic speed adjustment, multi-hook synchronization, and electronic sway control. This crane efficiently handles heavy offshore wind components while reducing operational costs through energy-saving design, establishing itself as a cornerstone for high-quality development in China’s wind power industry. It showcases the company’s leading R&D and manufacturing capabilities in large-tonnage specialized lifting equipment.

Core Technical Advantages

1. 500-Ton Heavy-Load Adaptation with Dual-Trolley Efficient Coordination: With a rated lifting capacity of 500 tons (500+250/32t configuration), the dual-trolley design enables multi-hook coordinated operations. It accommodates both single heavy components (e.g., 500-ton nacelles) and can be split for simultaneous transport of multiple parts, perfectly matching the diverse lifting requirements of offshore wind power heavy equipment.
2. Lightweight + Intelligent Energy Saving, Reduced Operating Costs: The hoisting mechanism features a lightweight design that reduces self-weight while maintaining structural strength. Combined with automatic speed adjustment (fast/slow), it dynamically optimizes operating speed based on load conditions, effectively conserving electrical energy. Compared to traditional cranes of equivalent tonnage, it achieves over 15% energy savings, aligning with the green development philosophy of offshore wind power.
3. High-Precision Synchronization + Anti-Sway, Doubling Operational Efficiency: Multi-hook high-precision synchronization technology ensures lifting errors ≤2mm, guaranteeing stable transport of heavy components. Full-machine electronic anti-sway functionality employs intelligent algorithms to real-time counteract hook sway, limiting swing angle to ≤±0.5°. This prevents component collision damage while significantly enhancing handling efficiency and safety.
4. High Lift + Comprehensive Safety for Marine Conditions: The high-lift design meets offshore wind equipment installation demands at elevated heights, effortlessly covering large turbine hoisting operations. Advanced digital and visual monitoring protection functions provide real-time oversight of work zones and equipment status. Paired with a full lifecycle management system, it enables end-to-end control of equipment operation, maintenance, and fault early warning, delivering comprehensive safety assurance for complex marine environments.
