Wind turbine tower suspension means

Abstract

A method of mounting elements in a wind turbine tower, whereby the elements are partly or completely attached to the wind turbine tower by means of magnetic attraction forces. Wind turbine suspension units may be attached to the wind turbine tower, preferably completely or partly to the inner wall by means of magnetic attraction forces, which prevent structure-weakening attachments to the tower or part of the tower.
