<p>PURPOSE:To facilitate laying of cable even into a long distance conduit, by coupling a rod between the tips of pulling wire and cable then fixing a plate and a movable board thereto through lubricant thereby feeding lubricant as the cable moves. CONSTITUTION:When a cable 2 is pulled into a conduit 7, a rod 10 is coupled between the tip of the cable 2 and a pulling wire 1. A flange type plate 11 is secured to the rod 10 at the side close to the cable 2. A movable plate 12 is mounted on the rod 10 at the side closer to the tip than the plate 11. Then the pulling wire 1 is pulled with lubricant L being filled between the movable board 12 and the plate 11 so as to press the lubricant L through frictional force between the movable board 12 and the conduit 7 thus laying the cable 2 while applying the lubricant L onto the inner face of the conduit 7.</p> |
