The invention relates to a nacelle lifting tool and method for lifting the nacelle (1) of a wind generator in relation to the rotating ring (2). The inventive tool is formed by first and second fixing means which replace brake callipers (4) that are disposed on front and rear lifting means. The aforementioned lifting means are supported by supports (13) which are fixed in the form of braces to the vertices of a regular polygon formed by beams (12). The inventive method consists in removing the brake callipers (4) in order to install the fixing means in an alternating manner and fixing said means vertically. The first and second fixing means include rear (10) and front (11) callipers and the lifting means include hydraulic jacks (16, 17).
