<p>PURPOSE:To simply and quickly lay a cable with a small force throughout a whole length of a cable tray by employing a cable laying equipment capable of automatically feeding out the cable in a direction in which a tension in the cable can be reduced and by pulling a pilot rope connected to the tip of the cable. CONSTITUTION:A plurality of cable laying equipment 100, which is formed to send out a cable 7 with a roller 20 in the direction which reduces a tension applied to the cable 7, are separately installed at certain intervals in the longitudinal direction of a cable tray 1. To the tip of a cable to be laid, a pilot rope 70 is connected, which has a smaller weight per unit length than that of the cable 7 and a length equivalent to the longest span between the cable laying equipment 100 installed separately. This pilot rope 70 is attached to the first cable laying equipment 100 and then subsequently attached to the other following cable laying equipment 100 while being pulled along the cable tray 1, and the cable can be laid without directly holding the middle of the cable 7.</p> |
