The invention relates to a system and method for locking a rotor of a wind turbine during extended maintenance. A rotor lock assembly for locking the rotor of the wind turbine comprises at least one removable rotor lock. Each removable rotor lock is provided with a shell comprising an opening and a mounting part, a pin shaft positioned in the opening and a locking mechanism, wherein the opening extends from the first end to the second end of the removable rotor lock, and the mounting part is suitable for being mounted on a bearing shell adjacent to a rotor lock plate of the rotor. 本发明涉及用于在延长的维护期间锁定风力涡轮转子的系统和方法。一种用于锁定风力涡轮的转子的转子锁组件包括至少一个可移除的转子锁。可移除的转子锁具有包括开口和安装部分的壳体、定位在开口内的销轴以及锁定机构。开口从其第一端延伸到第二端。安装部分适于安装到与转子的转子锁板相邻的轴承壳体。
