ABSTRACT:
In a method of hanging a cable by using spiral hangers on a messenger wire installed between a pair of electric utility poles, one end of a spiral hanger and a leading end of a pull rope are connected to a leading pulley in the vicinity of one of the electric utility poles. A spiral hanger having an inner diameter greater than the sum of the outer diameter of the messenger wire and the outer diameter of the cable is transported toward the other of the electric utility poles while surrounding the messenger wire and the pull rope. The other end of the spiral hanger is connected to one end of a succeeding spiral hanger by using a joint sleeve, and this operation is repeated. When the leading pulley arrives at the other of the electric utility poles, the spiral hangers are fixed to the messenger wire using fixing devices. After that, the pull rope is pulled so as to pull the cable connected to the tail end of the pull rope through the spiral hangers. With this operation, the cable can be installed by work performed only in the vicinity of the electric utility poles.
