Method and device for erecting a wind turbine to generate electric power stabilizes a crane boom by a support fastened to a wind turbine tower or a heavy lifting auxiliary crane on the top of the tower.

摘要

A wind turbine has a tower (26), a machine housing with an electric generator and a blade rotor to drive the generator both hoisted and mounted after the tower is erected. While raising the heaviest parts of the wind turbine, hoisting apparatus is supported on the tower to ensure appropriate stability. A crane (1) boom (4) is stabilized by a support fastened to the tower or a heavy lifting auxiliary crane (28) on the top of the tower.
