Abstract
A rotor restraining apparatus () and methods for a wind turbine (). The rotor restraining apparatus has a locking element () associated with a rotor () of the wind turbine, a rotational axis of said rotor defining an axial direction, the locking element being at least part-circular in form. The locking element comprises a plurality of engagement formations () disposed on a periphery thereof. The apparatus also has a restraining member (), comprising a plurality of engagement formations (). The restraining member is movable substantially along said axial direction between: (a) a non-restraining position; and (b) a restraining position in which the restraining member engagement formations are able to engage the locking element engagement formations. At least a portion of the restraining member has an arcuate form that substantially matches the curvature of the locking element.
