A wind turbine support assembly comprises a mast 100, a foundation of e.g. three helical piles 400c and at least three struts 200c each pivotably connected by a pin to the mast at a first connection point 210c, at e.g. 5m along the mast, and at the other end by pivot pins 220c to respective foundation connection points. Adjustable length links 300c, e.g. turnbuckles, are pin pivoted 310c, 320c between each strut and second mast connection point, e.g. at the base. The foundation may be installed to a lower accuracy and tower may be adjusted vertical to higher accuracy using the adjustable links. Foundation end fittings on two struts may form a pivot axis (Fig. 1) about which the assembly may pivot between horizontal and vertical by hydraulic rams acting between the pivot bearing foundations and the mid point of a scissoring linkage attached to the third foundation. |
