WIND TURBINE ASSEMBLY SYSTEM AND RELATED METHOD
The invention relates to a system for assembling a wind turbine without using cranes, which has lifting systems arranged peripherally to the tower , with a lifting platform, a base and an internal lifting mechanism. The lifting platform engages with different coupling tools that can be supported on an auxiliary column and thereby raise or lower the consecutive modules of the tower.

SCREWED CONNECTION FOR A MODULAR BLADE
The invention relates to a screwed connection for a modular blade, formed by a single bolt which connects inserts disposed on the flange of the beam, screwing together two opposing modules . A spacer is added to the central portion of the bolt and the bolt is pretensioned by means of stretching, with the modules being separated mechanically using a mechanical separator or thermally with the application of heaters to the bolt and coolers to the spacer.
