Abstract
A maintenance platform for suspension on support cables, in particular for maintaining rotor blades of wind turbines, wherein the maintenance platform is formed by at least two sub-platforms defining a working plane, wherein said sub-platforms are swivably connected to each other by a swivel joint with a swivel axis substantially perpendicular to the working plane.
Claims5
A maintenance system in combination with a wind turbine attached to a tower, the wind turbine comprising at least two rotor blades attached to a rotor hub and forming a rotor plane extending infinitely outwardly in a direction essentially perpendicular to a rotational axis of the rotor hub, the maintenance system comprising:
- a maintenance platform comprising:
- at least two sub-platforms defining a working plane, wherein said sub-platforms are swivably connected to each other by a swivel joint having a swivel axis substantially perpendicular to the working plane,
- first, second and third support cables, wherein the first, second and third support cables are each attached to one of the at least two sub-platforms and none of the support cables intersect the rotor plane, and
- wherein the first support cable is suspended from a cable suspension member which is attached to the rotor hub, wherein said cable suspension member bears the first support cable on an opposite side of the rotor plane from the tower and at least one of the second and third support cables is directly attached to a nacelle of the wind turbine.
