Caterpillar‘s 990H wheel loader comes with the same cycle times, standard hauler pass matches and impeller clutch torque converter as the 990G Series II, but offers lower engines emissions and increased efficiency. Engineered for mining, handling bulk materials and performing high-volume earthmoving, the standard-lift 990H loads 60- to 70-ton capacity trucks and the high-lift version loads 100-ton capacity trucks. Rated payload with the standard lift is 16.5 tons and bucket capacity ranges between 11 to 12 cubic yards. The machine’s Cat C27 12-cylinder engine rates at 627 horsepower with a displacement of 1,648 cubic inches. The air-to-air aftercooling system reduces engine emissions and helps maintain performance at high altitudes.
