Wind power plant has mast segments raised up by lift device in order to insert new segment in from below

摘要

The wind power plant has a mast (4) made up of segments (8) each placed one above the other at least in part so that each new segment to be installed can be inserted beneath an existing segment which has previously been raised up by a lift mechanism (14). The mast sections are tensioned against the ground by cables or other traction means. The tensioning force can be adjusted by an electronic control device taking into account the increase in the height of the mast.
