PURPOSE:To perform travelling and stopping on the fixed path smoothly without slips both on a straight line and a curve by engaging a pinion, interlocked with a travel-drive unit on the self-travelling truck side, with a rack fitted at a guide rail, and providing a feeder device on the running rail side and a current collecting device on the bracket side. CONSTITUTION:A self-travelling truck 20 supported at running rails 1A, 1B through wheels 22A, 22B travels by rotating a pinion 27 engaged with a rack 11 by a travel-drive unit 24. At this time, the travel is performed on the fixed path by the guide of a guide rail 10 positioned between the running rails 1A, 1B through a guide roller 30. Travelling/ driving force can be thereby obtained at the cross direction center part of the self-travelling truck 20 without generating slips and the like, and running and stopping on the fixed path can be performed smoothly and reliably both on a straight line and a curve. In this case, a feeder device 14 is provided on the running rail side and a current collecting device 33 is provided on the bracket side. |
