The truck is powered by a 250 HP four-cycle naturally respirated engine, and the gear train efficiency is 0.82. The site elevation is 3,500 feet. When fully loaded, the truck has a gross weight of 45 tons, with 65% of the weight carried by the rear (driving) wheels. The haul road has an 8% uphill grade and a tire penetration of 1.8 inches.
