Definitions

• the heights of wind power plants have been continuously increased, as the unit size of power plants applied in wind farms has been continuously increased because of e.g. better profitability of energy production that can be achieved with larger units.
• the hub heights of wind power plants were normally in the order of about 30 m above the ground, whereas in the largest power plants at present, for example, in the 5 MW power plants recently designed to be taken into use e.g. in Denmark, the hub heights are as great as about 165 m.
• the mounting of wind power plants which are even clearly smaller than this last-mentioned height may be very laborious and difficult by the methods of prior art, e.g. when they are installed on top of hills or mountains which are, nev- ertheless, normally very good locations for producing wind power, in view of the wind conditions.
• Fig. 1 shows an installation construction used in a method according to the invention, seen from the direction of a transfer opening in the construction, before the parts of the wind power plant are transferred to the inside of the installation construction;
• suitable lifting devices for example, shackles
• the installation construction 1 already comprises at least one mast element 3' lifted up
• the traction cables 14a and 14b led to the inside of the installation construction 1 are connected to the next mast element 3 to be transferred to the inside, at fixing points 16a and 16b formed on its both sides.
• the traction cable 14c led to the outside of the installation construction 1 is connected to a fixing point 16c at the rear end of the next element 3 of the mast 4 to be transferred to the inside.
• the generator unit 20 of the wind power plant is fixed to the upper end of the uppermost element 3" of the mast 4 in the step when the end of this element has risen above the installation construction 1.
• the steps of transferring, connecting and lifting new lower elements of the wind power plant are repeated until all the lower elements of said mast have been placed, one on the other, and connected to each other.
• the set of propellers of the wind power plant is connected to the generator unit in the step when the generator unit at the end of the uppermost element 3" of the mast has risen so high that the propellers of the set fit between the hub connection in the generator unit 20 and the ground surface.
• the lowermost, last element 3' is connected so that it is no longer lifted up, but after being transferred into its place in the installation construction, this element is connected to the foundation 17.
• the transfer device used for transferring the elements of the wind power plant could be alternatively implemented by means of, for example, chains, lifting straps, mechanical gripping arms, roller conveyors, conveyor belts, etc. to achieve a function corresponding to that described above.
• the elements of the wind power plant can also be transferred to the inside of the installation construction in the form of parts smaller than a single element, from which the actual elements to be lifted are then assembled.
• the step of transferring also in this case there is no need for turning from the transfer position to the installation position but the parts are thus assembled inside the installation construction so that they will be ready in the correct installation position.
