Abstract

Ved montering af vinger (22, 24) vindmøller af den art der ikke omfatter gearkasser, forekommer der problemer med monteringen af vingerne, eftersom møllenavet ikke kan drejes under montagen. Dette medfører ofte tids- og omkostningskrævende flytninger af de løftekraner der skal løfte nævnte vinger til og fra deres tilslutningspunkter på møllens nav (26). Desuden medfører de kendte montagemetoder at vingen ikke føres vinkelret ind i navet, hvilket medfører behov for komplicerede operationer med kranen. Der angives en fremgangsmåde til afhjælpning af nævnte problemstillinger, der går ud på at foretage en drejning af nacellen (40) imellem montering af vingerne, hvorved der opnås en direkte indføring af vingen i navet, hvor der opereres med en kort kran ud lægger arm (32), og hvor der ikke opstår noget behov for flytning af kranen (30).When installing blades (22, 24) wind turbines of the kind that do not include gearboxes, problems occur with the blades mounting since the mill hub cannot be rotated during assembly. This often involves time and costly relocation of the lifting cranes to lift said blades to and from their connection points on the mill hub (26). Furthermore, the known mounting methods mean that the blade is not inserted perpendicular to the hub, which necessitates complicated operations with the crane. There is disclosed a method for solving said problems, which involves turning the nacelle (40) between the mounting of the blades, thereby obtaining a direct insertion of the blade into the hub, operating with a short crane laying arm ( 32) and where there is no need to move the crane (30).
