ABSTRACT:
A line stringing apparatus particularly suitable for stringing the center line of a tower entirely from an aircraft while suspending a threading member (11) to which a threading line (16) is attached. An elongated threading member (11) carries a hook-shaped leading line coupling part (12) that is oriented so that the shank portion (21) is lengthwise of, the bend portion (22) is transverse to, and a free end portion (23) extends back toward the trailing end of the threading member. A hook-shaped trailing line coupling part (13) is opposite to, spaced from, and faces the hook of the leading line coupling part. The trailing shank portion (41) is arranged substantially lengthwise of, the trailing bend portion (42) is substantially transverse to, and the trailing free end portion (43) extends back toward the leading end of the threading member. The trailing shank portion pivots about a pivot (49) that is substantially transverse to the threading member to swing between a horizontal position and an upright position when suspended by the aircraft. An upper catch (61 ) and a lower catch (62) on the same bracket on the threading member temporarily secure the threading member to the tower.
