Siemens Wind Turbines

Moventas’ 35-year wind industry experience and core technologies now harnessed for Siemens 2.3 and 3.6 fleets.

Cost-effective factory and up-tower services for Siemens turbines

Moventas has reverse engineered Winergy gearboxes from Siemens 2.3 and 3.6 turbines for factory and up-tower services. Our ExtraLife™ upgrades eliminate the known weaknesses and failures such as planet bearing failures and gear failures in general.

Especially for North American market we have developed planetary stage swap with our mobile service units. This eliminates the need for crane or spare gearbox in case of planet failure as the repair can be implemented on site.
