Abstract: The invention relates to a wind turbine with internal transport devices which comprises: a power train including a generator (41) located in front of the rotor (15) and actuated directly by said rotor (15), a tower (11) and a supporting structure (13) mounted on the tower (11); the rotor (15), which is supported by a main non-rotating shaft (29) connected to the supporting structure (13) by means of at least one bearing, comprising a hub (17) and at least one blade; the generator rotor (45) being rigidly connected to the rotor hub (17) and the generator stator (43) being rigidly connected to the main shaft (29), the main shaft (29) being a hollow shaft which includes one or more transport devices, such as a device (61) for transporting hanging loads or a carriage (71) for making it easier to replace parts of the generator and/or to transport persons.

Abstract: A blade root extender for a wind turbine assembled between the blade root and a hub fixed to the wind turbine's nacelle. The extender is made up of a hollow, corrugated cylinder and one or two terminal flanges with holes for some preloaded stud bolts that apply pressure to the blade root extender.

Abstract: Wind turbine having a rotor, a nacelle frame (13) housing with electrical generation means coupled to the rotor hub (11), braking means and control means of the drive train rotational position, the nacelle frame (13) and the rotor hub (11) having an arrangement for preventing the rotor hub (11) rotation when certain maintenance or assembly activities should be carried out, the arrangement including at least one sliding pin (21) in the nacelle (13), first actuating means (31) for pushing/pulling it axially into/from at least one corresponding hole (23) in the rotor hub (11) and means for allowing vertical and lateral adjustment displacements of the sliding pin (21) so that it can remain concentrically aligned with the hole (23) when it is inserted into it.

Abstract: A movable independent crane system for moving or replacing components during maintenance operations and for mounting wind generators, including an auxiliary portal crane providing a portal structure designed to be movable around a pod about a rotation shaft. The mobile independent crane system includes raising devices being part of the crane system and designed to allow self-raising of the crane system because the mobile independent crane system is anchored to the pod through an anchoring unit and because the mobile independent crane system is designed to operate over the pod and outside the pod sides.
