muy dilatados. con las consiguientes perdidas economicas.very dilated with the consequent economic losses.
Pues bien. para realizar las labores de mantenimiento y trabajos en altura de los aerogeneradores, se utilizan sistemas basados en plataformas colgadas de una u otra forma, y que permiten el mantenimiento de la correspondiente pala del aerogenerador.As well. To carry out the maintenance work and work at height of the wind turbines, systems based on platforms hung in one way or another are used, and that allow the maintenance of the corresponding wind turbine blade.
Aunque los sistemas de plataforma son estructuralmente simples, sin embargo presentan un problema que se centra fundamentalmente en los siguientes aspectos:Although platform systems are structurally simple, they nevertheless present a problem that focuses primarily on the following aspects:
- La plataforma ha de ser transportada hasta el aerogenerador mediante camiones o gruas especiales, lo cual supone un handicap grave debido al emplazamiento de los aerogeneradores, que suele ser en lo alto de lomas de diflcil acceso.- The platform has to be transported to the wind turbine by means of trucks or special cranes, which is a serious handicap due to the location of the wind turbines, which is usually at the top of difficult access hills.
- La plataforma esta prevista y realizada convencionalmente para permitir unicamente el acceso a las palas del aerogenerador, y lo que es peor. solamente a la cara interior de dichas palas frente al mastil.- The platform is planned and carried out conventionally to allow access to the wind turbine blades only, and worse. only to the inner face of said blades in front of the mast.
- Ademas de las palas del aerogenerador, el resto de elementos de este requiere para su mantenimiento o reparacion que los operarios escalen, con las consiguientes penalizaciones en tiempo y economia.- In addition to the blades of the wind turbine, the rest of the elements of this one require for its maintenance or repair that the operators scale, with the consequent penalties in time and economy.
El documento U201200374 del mismo solicitante de la presente invencion permite el mantenimiento de las palas pero no del rotor y de la gondola, lo que resulta una ventaja practica muy importante en este tipo de aplicaciones.Document U201200374 of the same applicant of the present invention allows the maintenance of the blades but not of the rotor and the gondola, which is a very important practical advantage in this type of applications.
