ABSTRACT:
The problem of stringing power transmission lines via a line-holding structure that has an upper cross support and no side access, such as the center strand under a cross support on a tower, is solved by the methods and apparatus disclosed. The stringing apparatus is carried in a depending manner from the aircraft by a hoist line and enables the insertion of a sock line through the line-holding structure, followed by the pulling of the line therethrough. Different forms of the stringing apparatus enable an insertion with a needle-type structure, a pull-push structure, a pivoting gate structure, and a rotary annular carrier or ring segment structure. After the sock line has been strung, one end is secured to a power line which is then threaded through the line-holding structure to complete the stringing of a center strand of power line.
