Abstract
A pitch motor trolley and a method for operating a pitch motor trolley are disclosed. Wind turbines use pitch motors to change the pitch of its blade. At times, the pitch motor may need to be replaced, which can be difficult. The pitch motor trolley can move the pitch motor into/out of the hub, and includes a base structure, another structure connected to the base structure at one end and at another end to a track, and a trolley/hoist moving along the track. The base structure can be connected to a part of the nacelle for the pitch motor trolley to move the pitch motor through the nacelle into the hub (and vice versa). The base structure may also be connected to a part of the hub for the pitch motor trolley to move the pitch motor through a ceiling in the hub to the ground (and vice versa).
