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.
