<p>PROBLEM TO BE SOLVED: To realize a cable laying method with which the slipping down problem of a long cable can be solved, without using additional expensive auxiliary facility, and in addition, no damage is given to the surface of the cable at the time of laying the cable on a long-distance slope. SOLUTION: At laying of a cable 1 on a long-distance slope, such as gallery, etc., many rollers 2 are arranged along a cable laying route. The cable 1 is laid by making the cable 1 run on an advancing path formed of the rollers 2. Braking rollers 22 which give braking forces to the running cable 1 are mixedly arranged among the rollers 2, so as to give frictional forces to the cable 1 at multiple points.</p> |
