Construction methods and construction equipment of wind power generation equipment

摘要

PROBLEM TO BE SOLVED: To dispense with a large crane for setting a wind power generating device and to carry out the work quickly, safely and securely.;SOLUTION: A tower 4 is constructed by connecting a plurality of segmentation towers upward one by one. A mast 5 comprising a plurality of steps of mast nearly in a U shape in plan view is arranged so as to surround the tower 4 and capable of telescopically rising/descending. The lower end part of the tower 4 and the lower part of the mast 5 are supported by a jacket type foundation structure 2. While stably supported by the established part of the tower 4, the mast 5 is successively raised. A lifting mechanism 15 installed on the upper part of the mast 5 lifts the segmentation towers for completing the tower 4. A generator 6 and a rotor blade 8 are lifted and installed on the upper part of the tower 4. After that, the mast 5 is lowered/contracted to be removed/dismantled from the jacket type foundation structure 2.;COPYRIGHT: (C)2005,JPO&NCIPI
