A wind turbine comprising:
- a tower,
- a nacelle mounted on the tower, and
- a movable container selectively mountable on a lower part of the nacelle, the movable container having sidewalls that define an interior of the moveable container and housing a hoisting mechanism located within the interior of the movable container, the hoisting mechanism comprising at least one winch and at least one cable coupled to the at least one winch,
- wherein the at least one winch and the at least one cable are configured to be operatively coupled to the nacelle to hoist the moveable container to the lower part of the nacelle to a mounted position in which the moveable container is attached to the lower part of the nacelle and to lower the moveable container away from the lower part of the nacelle, and
- wherein the at least one winch and the at least one cable are configured to be operatively coupled to a wind turbine component to lower the wind turbine component from the nacelle and to hoist the wind turbine component to the nacelle while the moveable container is in the mounted position.
