Title:
クレーンを使用しない風力発電設備のローターブレードの取付け方法
Document Type and Number:
Japanese Patent JP2006513356
Kind Code:
A
Abstract:
It has already long been known to use mobile cranes for mounting rotor blades to a wind power installation. Such cranes pick up the rotor blade at the base of the wind power installation and take it to the rotor blade connection of the hub of the wind power installation so that the rotor blade can be connected to the hub. That connection is usually made by screw means, in which case screw bolts are let into the connecting flange of the rotor blade and project into corresponding bores in the rotor blade connection of the hub so that nuts can be screwed on to the screw bolts. The object of the invention is attained by a blade mounting method having the features of claim 1. Advantageous developments are set forth in the appendant claims. A method of mounting or dismantling a rotor blade of a wind power installation without using a crane to a rotor blade connection on a hub of a rotor of the wind power installation, wherein at least one cable is stretched between a part in the hub region of the wind power installation and the bottom region of the wind power installation and the rotor blade is moved along the cable upwardly upon mounting or downwardly upon dismantling.
