Leveraging Experience.

Efficiency Since 1995

When we carried out our first oil change on a wind turbine back in 1995, the average WTG had a power rating of 600 KW and a hub height of 45 m. Today, the usual hub height is over 100 meters, and today’s WTGs often produce more than 3 MW.

At the same time, the standards for gearbox and hydraulic oils have become commensurately more stringent, and of course the same holds for the personnel who carry out oil changes. Their work has not only become physically more strenuous; they also have to have the versatility and expertise required to deal with  new challenges and technology. Of course, our teams can count on advanced vehicles developed by Lonsdorfer in house to help them carry out their work as efficiently as possible.
