PURPOSE:To lead in wiring/piping material in stabilized state while suspending in the center by ensuring a space for containing the wiring/piping materials in a duct and arranging the running paths on the opposite sides of the duct thereby running a suspension vehicle while supporting on the opposite sides thereof. CONSTITUTION:A rigid priming wire P is inserted into a duct 1 from one end thereof and connected, at the other end thereof, with a wiring/piping material X suspended from a suspension vehicle 2. The priming wire P is then pulled back and the suspension vehicle 2 runs on a running path 12 in the duct 1 thus leading in the wiring/piping material X while suspending up to one end of the duct 1. Subsequently, a tension rope P1 is pulled from the other side of the duct 1 to actuate the releasing means for the preceding suspension vehicle 2 thus falling the wiring/piping material X at a lead-in position in the duct 1. The released vehicle 2 moves toward the other end of the duct 1 and strikes against an adjacent vehicle 2 to actuate the releasing means thereof. The operation is repeated and the vehicle 2 is separated sequentially from the material X thus laying the material X. |
