<p>PURPOSE:To independently control the movement of a vehicle without mounting a controller on each vehicle by dividing feeder wires provided in parallel with rails of the vehicle into a plurality of zones, and connecting the divided wires to respectively control circuits, thereby supplying voltages individually and independently to the zones. CONSTITUTION:Rails 2 of a movable hook 1 are laid in an endless manner circularly through a rolling step 3, an annealing step 4 and a delivering unit 5 in a wire manufacturing factory. Two feeder lines 6 are provided along the rails 2, and at least one of the lines 6 is divided at the prescribed positions into current feeder wires 6a-6f, which are connected to a control circuit 7 in a stationary control board, and the circuit 7 is applied with voltages respectively controlled for the wired 6a-6f. A drive motor 10 and movable roller 12 connected through a reduction gear 11 to the motor 10 are arranged in the hook 1. Two current collectors 8 are provided in contact with the wires 6 on the hook 1, the collectors 8 are contacted longitudinally at the side of the wires 6a-6f, and improper energization of the divided portions can be eliminated.</p> |
