The invention concerns a method for the construction of a wind-power unit having a wind turbine (2) supported by a tower (1 ), the tower being composed from a plurality of vertically distributed sections (11 a-11 e). The method according to the invention comprises placing a first section (11a) on a construction site of the wind-power unit, lifting the first section (11a) a distance corresponding to at least the length of a second section (11b), placing the second section (11 b) on the construction site, attaching the first section {11a) to the second section for the formation of a composed tower part, and lifting the composed tower part a distance corresponding to the length of a next additional section (11 c). This is then carried out a number of times depending on how many sections that the tower is composed of, after which the last set out section (11 e) is anchored on the construction site. The invention also concerns a lifting device for carrying out the method and a use of the constructed wind-power unit. |
