The present invention concerns a wind power installation having a rotor with at least one blade and an adjusting device for the rotor blade. With increasing installation sizes and thus larger rotor blades larger drives are also required for rotor blade adjustment. Particularly in the cas e of damage such drives in turn require a higher level of logistical, time and material expenditure. In order to avoid those disadvantages there is provided an adjusting device with more than one drive. By virtue of that arrangement each drive only has to furnish a corresponding fraction of the power output, it can be of a correspondingly smaller design configuration, and it imposes a correspondingly lower loading on the subsequent components.
