Abstract
A system and method of use for attaching a safety rope to an elevated portion of a tower, e.g., an electric power transmission tower, so that the rope extends along the tower's leg from the elevated portion to a lower portion, e.g., the ground, to enable a worker may be secured to the rope by a safety device, e.g., a rope grab, to protect the worker from a fall. The system comprises an air rifle for shooting a projectile having a light weight flexible filament secured to it over the elevated portion of the tower, the safety rope, and plural rope-retaining gates. Once the projectile has been shot over the tower to carry the filament over the elevated portion the safety rope is connected to the filament and pulled over the elevated portion of the tower. The safety rope is then secured in place extending vertically between the elevated portion and the ground. Plural gates are mounted on the tower's leg at spaced locations therealong to hold the safety rope close to the tower leg so that it cannot flap or blow around in the wind. A worker can then attach a safety device on the rope and climb up the tower, while being protected from a fall therefrom.
