trolley assist (Trolley Assist is an alternative power source for diesel haul trucks, which are outfitted with pantographs to draw power from an overhead power line. This allows trucks to use the diesel generator on level or downhill drives while employing electric power for climbs. The greater power of the electric drives speeds the truck faster on the uphill drives. The diesel engine can idle during uphill drives, reducing fuel consumption. This is especially useful for deep mines with many uphill drives. ixtra) |
