A Generаl Cоntrаctоr is using а 25 CY articulated dump truck tо haul excess excavated material from a construction site. 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. The coefficient of traction is 0.65. Determine if the equipment is capable of doing the job. Check max usable tractive force vs. required rimpull. Determine the adjusted available rimpull of the truck in each of the indicated gears. What will be the maximum speed for the truck? Gear Speed (mph) 1 3 2 9 3 14 4 23
