Abstract
The invention relates to methods of handling wind turbine blades and mounting said blades on a wind turbine, said method comprising the steps of lifting a wind turbine hub to the nacelle of wind turbine with a lifting system and mounting the hub on the nacelle. Further, the method comprises the steps of gripping at least one wind turbine blade with a lifting system including at least one gripping unit for handling wind turbine blades, lifting said at least one wind turbine blade into close proximity to said hub, and mounting said at least one wind turbine blade on said hub. The invention also relates to a gripping unit for handling a wind turbine blade during transport.
Claims54
Method of handling wind turbine blades and mounting said blades on a wind turbine, said method comprising:
- lifting a wind turbine hub to a nacelle of a wind turbine and mounting the hub on the nacelle or lifting the wind turbine hub and the nacelle as one and mounting the nacelle, including the hub, on a wind turbine tower,
- establishing a rigid connection to surface areas on sides of a wind turbine blade with a lifting system for handling wind turbine blades,
- lifting the wind turbine blade with the lifting system for handling wind turbine blades,
- lifting said wind turbine blade to a vertical position below and in close proximity to said hub, and
- mounting said wind turbine blade on said hub.
Method of handling wind turbine blades and mounting said blades on a wind turbine, said method comprising:
- lifting a wind turbine hub to a nacelle of a wind turbine and mounting the hub on the nacelle or lifting the wind turbine hub and the nacelle as one and mounting the nacelle, including the hub, on a wind turbine tower,
- gripping at least one wind turbine blade with a lifting system including at least one gripping unit for handling wind turbine blades,
- lifting said at least one wind turbine blade into close proximity of said hub, and
- mounting said at least one wind turbine blade on said hub.
System for handling wind turbine blades and mounting said blades on a wind turbine, said system comprising:
- a gripping unit for establishing a rigid connection to surface areas on sides of a wind turbine blade and a lifting assembly.
Gripping unit, for handling a wind turbine blade comprising:
- a gripping means for establishing a rigid connection to surface areas on sides of the wind turbine blade.
A gripping unit for handling a wind turbine blade, comprising:
- a yoke structure;
- a first clamping jaw disposed on the yoke structure;
- a second clamping jaw disposed on the yoke structure generally opposite the first clamping jaw;
- an eyelet for connecting the gripping unit to a lifting system;
- wherein at least one of the first and second clamping jaws are actuatable so as to selectively grip the wind turbine blade between the first and second jaws;
- and
- wherein the gripping unit is liftable and maneuverable by the lifting system.
