Abstract: Footing used for the foundation of a wind turbine tower characterized because it provides a stable horizontal platform (1) located at the surface, upon which the tower sections and the heavy elements that are subsequently mounted, viz., gearbox, generator, hub and blades, can be set without sinking. The footing is characterized by its inverted truncated cone shape, and by the savings in material estimated at 20%, as well as for its union with the tower (4) through a pedestal (3) and its corresponding embedded tensioning elements in the footing.
