Grue portique MG60t pour la manutention de pales et de nacelles d'éoliennes lourdes

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 Grue portique bipoutre, 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.
