<p>PURPOSE:To lay a cable in a spiral suspension wire without rotating a heavy cable supplying means by providing a winding means which winds the laid cable spirally in front of the cable supplying means. CONSTITUTION:The suspension wire 12 is inserted into the cable supplying means 24, the winding means 38 having a rotatable roller 44 is fitted in front of it, and an intruding means 22 which has an expanding jig 30 is provided atop of it through a rotary joint 46. The means 24 is provided with a feed-out guide 48 and the means 22 is provided with a receiving guide 50. When a cable insertion space 16' is spiral, the means 22 rotates while expanding an entrance 16'a by the jig 30, but neither the means 24 nor 38 rotates, so the cable 20' is laid by being wound around the means 38 between guides 48 and 50 and the devide is rehung after one-span laying. For this purpose, the winding means is provided to lay the cable in the spiral suspension wire without rotating the heavy supplying means.</p> |
