Background
Many works such as overhead transmission line changes insulator chain, damper, repair wire all need the staff to climb on the wire, for the reliability of guarantee power supply, reduce the electric quantity loss, often adopt equipotential live working's mode to go on. It is a common working method for workers to climb a rope ladder to reach an equipotential. In the process of climbing the rope ladder by workers, the traditional method for preventing the person from falling from high altitude is to install a circulating transmission rope on the head or a lead of the rope ladder, before climbing the rope ladder, one end of the circulating transmission rope is tied on a back belt of a safety belt of the workers, and when climbing the rope ladder, the ground workers pull the other end of the circulating transmission rope to play a role in preventing falling. Because overhead transmission line's wire is apart from ground most to have two, thirty meters high, require high to climbing rope ladder personnel physical power, and the rope ladder is very unstable in the climbing process, often rocks, leads to climbing personnel to lose one's hand easily, the accident of pure falls. In case of accidental hand loss and foot loss of climbing rope ladder personnel, the impact force of the climbing rope ladder personnel during sudden falling is far greater than the arm force of the personnel pulling the protection rope on the ground. If the ground pulls the circumstances such as protection rope personnel appear reacting untimely or hand slip, will probably cause personnel high altitude accident of falling, have very big potential safety hazard.
