Rotor Blade Control

Around 27.000 wind turbines of different sizes and power have been installed in Germany. Regular maintenance work is required for granting their smooth operation inclusive assessment, maintenance and repair of the rotor blades.

The blades can be accessed by complex service platforms, granting short setting-up times irrespective of hub height. Thanks to special sling points and suspension to the machine nacelle the blades can be turned further anytime, allowing a fast completion of work. Major repairs can be executed parallely at different blade positions. Down times can be reduced to a minimum.

Blade assessments are made by high workers well trained and certified in rope access technology allowing a fast and cost saving execution of work. Rope access is both profitable for damage documentation and control and maintenance of lightning protection system.

The manifold blade controls include tip maintenance and control of drainage holes, as well. Aerodynamic parts are controlled for fixity and completeness.

The strong blade surface wear requires a regular control. Cracks, voids, lightning damages, gelcoat damages, installation or handling damages and delamination are possible symptoms.

The inner blade is examined as far as accessible. This includes visual control of hydraulic cylinders and tubes as well as burn marks or lightning strike. The tip rope is controled for tight fit and is adjusted where needed. Residual adhevises are removed and lamination and adhesive seams are controled.
