Helicopter Stringing Blocks are used for overhead line OPGW or conductors stringing operation with helicopters, to stringing pilot wire rope.
Helicopters are widely in construction of overhead transmission Lines now. Most of western countries have used helicopters for assembly of steel towers, transmission line stringing, and transmission line inspection and maintenance.
As the leading manufacture of power line stringing equipment and tools in China, Ningbo Dongfang started design and manufacture helicopter stringing tools from 1998. Cooperated with National Power Company and institute, we carried first helicopter stringing operation (test) in the west of China in 2001. We designed and manufactured single sheave, three sheaves and five sheaves helicopter stringing blocks with different structures. Our helicopter stringing blocks have been exported to more than 10 countries in the world.
