Beschreibung
Zusammenfassung:	The present invention relates to a wind turbine (1) comprising at least one wind turbine blade assembly (28). The blade assembly (28) includes a blade (5) and a pitch bearing arranged between the blade (5) and a hub of the wind turbine, the blade assembly further including two or more hydraulic pitch cylinders for pitching the blade in relation to the hub The wind turbine (1) is characterised in that the two or more hydraulic pitch cylinders (10) are arranged to expand in the same angular direction around the rotational axis of the pitch bearing (9). The invention further relates to a method for pitching a blade (5) of a wind turbine (1).
