<p>PROBLEM TO BE SOLVED: To easily remove a carrier on rails by removing the carrier from a connecting part after stopping the carrier at the connecting part detachably provided to a partial separating part of the rails so as to detach the connecting part from the rails. SOLUTION: A connecting part 14 is detachably provided between separated rails 1, while a lifting device 11 for moving up and down to attach and detach the connecting part 14 is provided. When a mobile carrier is removed, first, the mobile carrier is stopped at the center of the connecting part 14 in a rail carrying device. Next, fixing bolts and nuts in fixing parts are unscrewed. Then, after the connecting part 14 is detached from the rails 1 under a descending command to the lifting device 11, i.e., an attaching/detaching means, the mobile carrier is separated from the connecting part 14. Thereby, when the mobile carrier is removed from the rails 1, partial disassembly of the mobile carrier is not required for its removal so that the mobile carrier can be easily and certainly removed from the rails 1.</p> |
