<p>PURPOSE:To improve the accuracy of the stopping position by providing stopping zone rails at the positions to be stopped at self-traveling truck, and applying a voltage of reverse polarity to rails disposed at both sides of the stopping zone rail. CONSTITUTION:Stopping zone rails 20, 21 insulated by insulating pieces 16-19 are provided at the positions to be stopped at self-traveling truck of power supply rails 12, 13. When current collectors of trucks moving from a left direction completely arrive on the rails 20, 21, it becomes no voltage state that a power source is disconnected, and the truck moves in the output route rails 24, 25 by its inertia. When the collector enters on the rails 24, 25, a reverse voltage is applied Accordingly, a drive motor is reversely driven, the truck is reversely driven, and again enter the rails 20, 21.</p> |
