A pitch lock system for a wind turbine with a rotor having at least one pitchable or at least partially pitchable blade connected to the rotor at a interface, the blade having an outer blade part and an inner blade part, the blade parts being interconnected at an interface, having a pitch bearing construction with a first bearing ring and a second bearing ring for pitching at least a part of the blade in relation to the rotor. The pitch lock system has a movable toothed segment for interacting with at least one toothed element, and where the pitch lock system further includes an actuator for activating and moving the movable toothed segment into engagement with the toothed element, and thus, locking the pitch bearing construction and thus locking the pitch bearing in the actual position.
