PURPOSE:To attain assurance of safety under bad environment by allowing a rescue track having a traction and self-running mechanism to draw an unattended guided track to a safe place without access of a worker into the equipment if the unattended guided track is failed or in abnormality. CONSTITUTION:The rescue track 6 is driven by the induction system using inductive radio and the remote control system by an industrial television set. If the unattended track is stopped because of an abnormality, the rescue track 6 detects a low frequency current flowing into the guide wire imbeded under the floor and stops at an engagement position of the unattended guided track stopped at a loading course via a running line. The rescue track 6 tracks the induction track by using a traction mechanism 22 so as to move it to a safer place. If neither the guided track nor the rescue track 6 is operative, a video image in front is transmitted to a video receiver on ground by using a television camera 7 fitted to the rescue track 6. A receiver 12 of the rescue track 6 receives the image by using a remote control signal from an operating panel on ground, the running on the loading course and the running line is conducted so as to track the guided track. |
