Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; load-lifting facilities. ^ SUBSTANCE: proposed method includes lifting of section to be mounted by crane to level of opening of mounting holder and crane tower aperture, fixing of section to be mounted and bringing it into aperture of tower by turning, mounting of section in designed vertical position and connecting section and tower. Section to be mounted is lifted ion horizontal position, and in this position upper edge of section arranged close to tower, is hinge-connected with mounting holder or with upper part of crane. Then, using crane, section is lowered until it is free hanging on hinge joint and turned to tower into designed position. ^ EFFECT: reduced labor input at mounting operations, improved safety and simplified design. ^ 6 dwg
