大型風力タービンブレードおよびナセルハンドリング用MG60tガントリークレーン

Client Profile – Daoda Wind Energy

Daoda Wind Energy is a leading company in renewable energy equipment manufacturing, specializing in wind turbine production and installation. The company focuses on innovative solutions for large-scale wind power projects, including high-capacity turbines and offshore installations.

To improve the efficiency and safety of installing large wind turbine components, Daoda Wind Energy collaborated with DAFANG CRANE to deploy the MG60t ダブルガーダーガントリークレーン, achieving a breakthrough in high-altitude, heavy-duty lifting operations.

Project Overview – MG60t Double Girder Gantry Crane

To enhance the installation efficiency of large wind turbines, Daoda Wind Energy introduced the MG60t Double-Girder Gantry Crane, featuring:

• Box-type double-girder structure
• Span: 40 m
• Lifting height: 35 m
• Hydraulic Synchronous Hoisting System: 8 lifting points, synchronization error ≤0.1 mm
• Operation Modes: Wireless remote control + cabin operation
• Standards Compliance: GB/T 3811 crane design code, ISO 12482 safety certification
• Environmental Adaptation: High-altitude, long-span operations for wind turbine installation

This system enabled Daoda Wind Energy to achieve a major leap in safe and efficient high-altitude lifting for renewable energy equipment.

Core Application Scenarios
