A wind turbine having a nacelle being rotatably disposed on a tower is proposed. The nacelle has a first cavity, a generator housing portion disposed upstream to the nacelle having a second cavity, a hub disposed upstream to the generator housing portion with attached rotor blades at it having a third cavity. The first, second and third cavities communicates with one another. A rail-system has at least one rail-element having a device for lifting and/or transporting. The device for lifting and/or transporting is movable along the rail-system. The rail-system at least partially extends through at least two adjacent cavities.
1. A wind turbine, comprising:
a nacelle rotatably disposed on a tower comprising a first cavity;
a generator housing disposed upstream to the nacelle comprising a second cavity;
a hub disposed upstream to the generator housing comprising a third cavity;
a rotor blade attached at the hub,
a rail-system comprising a rail-element that at least partially extends through at least two adjacent cavities; and
a device for lifting and/or transporting that is movable along the rail-system,
wherein the first cavity, the second cavity, and the third cavity are configured to communicate with one another, and
wherein the rail-system extends through the first cavity, the second cavity, and the third cavity.
2. The wind turbine as claimed in claim 1 , wherein the device for lifting and/or transporting is detachably attached to the rail-system.
3. The wind turbine as claimed in claim 1 , wherein a length of the rail-system is extendable by adding a further rail-elements and/or by a telescopic mechanism.
4. The wind turbine as claimed in claim 1 , wherein a loading opening is disposed in or at the nacelle, and/or the generator housing, and/or the hub.
5. The wind turbine as claimed in claim 4 , wherein the loading opening is closable by a hatch
6. The wind turbine as claimed in claim 1 , wherein the rail-system is extendable outside the wind turbine through a loading opening of the nacelle and/or a loading opening of the hub.
7. The wind turbine as claimed in claim 1 , wherein the rail system comprises at least two different slopes.
8. The wind turbine as claimed in claim 1 , wherein the device for lifting and/or transporting is collapsible.
9. The wind turbine as claimed in claim 1 , wherein the device for lifting and/or transporting is a hoist and/or a crane.
10. The wind turbine as claimed in claim 1 , wherein a crane and/or a hoist system is disposed on an outer surface of the nacelle and/or an outer surface of the generator housing and is connectable to the rail system.
