<p>PURPOSE:To control the stop or start of a motor driven truck with a simple structure by providing the second control current collector to be disposed in a split zone adjacent to the rear of a slide contact split zone of the first control current collector when the truck is stopped. CONSTITUTION:When a relay CR3 provided on a control board 50 is closed, a split zone 18-1 is controlled to be stopped and shortcircuited with a power supply line 12-3. Thus, a motor driven truck 201 is stopped simultaneously when the first control current collector 36 enters the zone 18-1. At this time, the second control current collector 38 stops in the state of slidably contact with a split zone 18-2. When the first control current collector 36 of the following truck 20-2 enters the zone 18-2, the zone 18-2 is controlled to be held in stopped and shortcircuited state, and the truck 20-2 is controlled to be stopped in the state of bridge over the zones 18-2 and 18-3.</p> |
