WO2025176918A1

WO2025 176918 A1

Method for assembling blades and counterweights

The present invention relates to a method for assembling blades and counterweights on a direct drive wind turbine, characterised in that both the blades and the counterweights, either passive or active, are vertically lifted and lowered from the ground to the bushing by means of cables that are controlled by a lifting and lowering mechanism provided inside the bushing. The invention is also characterised in that the assembly method is combined with a wind turbine self-hoisting system.

WO 2025/133417 A1

Method for assembling and automatically lifting a wind turbine tower 

The invention describes a method for assembling and automatically lifting wind turbine towers using robotic systems. Ferrules made of wedges are built in situ along circular guides, with simultaneous internal and external welding, inspection, and painting. Work is carried out at two levels using vertically raised guides supported by columns. As ferrules are completed, they are lifted by a triangular system moving between columns. Once joined horizontally, these form tower sections. The method is suitable for tubular and frustoconical towers of 6–8 m in diameter and at least 200 m in height.

WO2024156924 A1

Wind turbine self-lifting system and method of assembly

The invention relates to a self-lifting system formed by three masts with their corresponding winches, pulleys and cables, a lifting triangle that moves up and down between said masts and supporting bases, wherein the three masts are braced against each other. The system has a temporary foundation for supporting the tower sections (9, 9′, 9″) and the tripod or transition part during the assembly process. The lower flange of the sections incorporates a connection ring, where the complementary elements formed by struts and horizontal beams extending from the vertices of the triangle are assembled and joined to each other by a crossbar. The struts and the horizontal beams move in a retractable manner and fold by means of associated systems in order to release the tower segments. The method of assembly used lifts different types of tubular and mixed wind turbines with lower latticework.

WO2023194631 A1

Method for rearing the root of a blade 

The present invention relates to a method for repairing the root of a blade having the following sequence: loosening the bolts of the root of the blade by removing the nuts in the bearing of the bushing . Lowering the blade to the ground using the Bladerunner® system.

WO2023214097 A1

Aligment and insertion system for lowering blades without using a crane

The invention relates to a system for lowering blades without using a crane, which solves the alignment and insertion problem resulting from the tilt and coning of the blade along the first/last 200-400 mm and the problem of space inside the hub.

WO2024062139 A1

Lightning-protection device in a modular blade

A lightning protection device for the metal joint of a modular blade composed of two parts: the tip area or outboard module, where the lightning strikes and is conducted to the blade joint, and the root area or inboard module through which The beam is conducted from the joint to the hub of the wind turbine.

WO2024028521 A1

Method for obtaining an improved segmented blade

The invention relates to a method for obtaining an improved segmented blade, wherein, for a blade 95 m long with the joint disposes 25-30 m from the blade tip. The cord and overall itchiness in the 20 m of the outboard module are reduced by 75% the outboard module is extended by 1 m joining elements per cap are reduced form 10 to 8, and the blade mass form 800 kg to 640 kg, reducing the impact of the joint mass on the rest of the wind turbine; and loads at the blade root are reduced by 11% without affecting wind turbine productivity.

WO2024133978 A1

Guiding systems for exchanging a wind turbine blade an use method

The invention relates to a guiding system for exchanging a wind turbine blade, which uses an internal lifting and lowering system fixed to a rotor. The guiding system is characterised in that it comprises semi-rigid passive retaining lines that form a safe catenary or track for lowering the blades without same hitting the tower or the ground as a result of incident winds of up to 15 m/s.

WO2024156924 A1

Wind turbine self-lifting system and method of assembly

The invention relates to a self-lifting system formed by three masts with their corresponding winches, pulleys and cables, a lifting triangle that moves up and down between said masts and supporting bases, wherein the three masts are braced against each other. The system has a temporary foundation for supporting the tower sections and the tripod or transition part during the assembly process.

WO2023281127 A1

Method for lifting and lowering blades without using a crane, and devices used

Disclosed is a method for lifting and lowering blades without using a crane, which uses an aligning and inserting device to solve the problem caused by the tilt and coning of the first/last 200-400 mm of the blade. The device comprises at least one hoist and a pair of cables coordinated by a pulley and screwed to a bearing by means of connecting elements at the ends thereof.

WO2024200881 A1

New transition piece for a wind turbine

The invention relates to a new transition piece for a wind turbine, formed by a hollow cylindrical monotubular segment with multiple connected rings, the upper part of the transition piece being the tower ferrule, the upper third comprising platforms and ribs, and the bottom part being a radial platform with brackets.
