<p>PURPOSE:To enable a following electric motor truck to be stop-controlled in good order, by hold-controlling divided sections and power feed lines in a stop- short-circuiting state between them and the motor control circuit of the following electric motor truck, when an electric motor truck is stopped. CONSTITUTION:When a distance between a divided section 18-1 and a power feed line 12-3 is stop-short-circuit-controlled by a truck controller 52, the first control current-collecting element 36 of an electric motor truck 20-1 enters the divided section 18-1, and at the same time, a relay CR1 is ON-driven to stop. At the same time, the hold circuit 64 of the electric motor truck 20-1 is controlled in the state of waiting for a following truck. When the first control current-collecting element 46 of the following electric motor truck 20-2 enters a divided section 18-2, the divided section 18-2 is hold-controlled in a stop-short- circuited state, and the following electric motor truck 20-2 is stop-controlled.</p> |
