FIELD: electricity.SUBSTANCE: at replacement of generator for a wind-driven power plant it is placed inside the wind tower, and the tower (140) has a door opening (150). The beam (300) used for replacement is attached to the hook of mobile crane (500) at the first position (310). The first end of the beam (300) used replacement with the second position (320) of attachment is introduced to the tower (140) through the door opening (150). The replaced transformer (200) is fixed to the second position (320) of the first end (300) attachment. Counterbalance (400) is fixed to the second position (320) of attachment at the second end of the beam (300) used for replacement. The second end of the beam (300) used replacement is diverted or inclined until the transformer is at the height of the door opening, and the crane hook is moved until the replaced transformer is out of the door opening (150).EFFECT: simplified mounting without use of special-purpose cranes.7 cl, 5 dwg |
