FIELD: power engineering construction, mounting of wire in extended spans. SUBSTANCE: method is realized with use of two helicopters. Ends of wire is fed from drum by first helicopter to first support. Drum is installed in unreeling gear hung from external suspension. After attachment of end of wire to nearest support wire is unreeled up to center part of span by movement of first helicopter where it is stopped. At same time attached section of wire is fed into roller near nearest support and is clung to second helicopter. Then both helicopters are moved towards far support. While first helicopter approaches is second helicopter stops over center part of span and first helicopter lays unreeling unit with drum on ground. Rope of pulling mechanism installed close to far support is attached to wire coming off unreeling unit, wire is disconnected from unreeling unit which is brought away by first helicopter. Wire is pulled by pulling mechanism. In this case second helicopter with roller keeps wire above obstacles. On completion of pulling roller is unloaded by descent of second helicopter, is disengaged and brought away. EFFECT: increased productivity of wire mounting. 3 dwg
