A wind turbine includes a tower, an energy conversion unit arranged substantially outside the upper tower cross-section and having a generator and a rotor with at least one rotor blade connected to a hub, a head carrier arranged on the tower and connecting the energy conversion unit to the tower, and a lifting device having a lifting cable for lifting and lowering the energy conversion unit. A supporting unit is fastened to the head carrier and extends in the longitudinal direction of the energy conversion unit. A redirecting assembly is arranged on the supporting unit for transferring the lifting cable from a substantially horizontal plane to a vertical plane. The redirecting assembly is connected to the head carrier or the supporting unit by a linear drive that causes a position change of the redirecting assembly in the direction of the longitudinal axis of the energy conversion unit. |
