AbstractA cable is previously introduced into a pipe in which the cable is to be laid. A wagon is caused to move through the pipe and the cable is raised up with the aid of an arm disposed at the fore part of the wagon until it abuts against the inner wall of the pipe. The cable is then fixed to the inner wall of the pipe by using fixing means disposed at the rear part of the wagon.
