Abstract: A locking arrangement for locking a hub (1) of a wind turbine against rotational movement is disclosed. The locking arrangement comprises at least one first locking part (6) and at least one second locking part (8). The first locking part(s) (6) is/are movable along a substantially radial direction relative to the rotational axis of the hub (1), between a locking position and a release position. Each second locking part (8) is adapted to retain a first locking part (6) when the first locking part (6) is in the locking position. The first locking part(s) (6) and the second locking part(s) (8) are arranged with one of them on the hub (1) and the other one on the base frame (5). Thereby, a first locking part (6) and a second locking part (8) prevent rotational movement of the hub (1) relative to the base frame (5) when the first locking part (6) is in the locking position, and allow such movement when the first locking part (6) is in the release position.
