<p>PURPOSE:To make cable laying work efficient by equipping this system with a high frequency transmitter, a high frequency sensor, and a cable holding means opening/closing mechanism. CONSTITUTION:A transmitter 18 is arranged on the side of sending out a laying cable 10 so as to send out a high frequency signal to the laying cable 10. This high frequency signal is detected by the pickup sensor 26 mounted on each cable drawing metal tool 14. A cable holding means 16 is opened by this detection signal by means of an opening/closing mechanism 34, and the cable 10 is pulled down automatically into a tray 12. For the high frequency signal sent out to the cable 10, a return loop of a high frequency signal is formed by the capacitance to the ground, and each of a plurality of drawing metal fitting 14 holding the cable is possible of signal detection, and this can be distinguished from the cable on other laying line. Accordingly, the cables 10 can be pulled down into the tray 10 and laid all at once in the condition that the target cable 10 is specified. Hereby, the work efficiency in the cable laying work improves.</p> |
