The HAMM HD+ 90i PH VV is a heavy-duty smooth drum tandem roller designed for efficient and high-quality compaction. It features two smooth, non-split vibration drums each measuring approximately 66.2 inches in width and 47.3 inches in diameter with a thickness of 0.7 inches, providing substantial static linear load of 157.4 pounds per inch. The drums generate centrifugal forces of up to 16,860 lbs (high) and 13,488 lbs (low), optimizing compaction effectiveness. Powered by a DEUTZ TCD 2.9 L4 diesel engine, it delivers 74.3 hp net power across 4 cylinders, ensuring reliable performance with a fuel capacity of 45.8 gallons. The roller weighs around 25,926 lbs fully operational and offers a maximum speed of 3.8 mph, suitable for various construction site needs. With a ground clearance of 31.5 inches and overall dimensions of 189 inches length, 6.1 feet width, and 9.8 feet height at the cab top, it balances maneuverability and stability. The machine features articulated steering with a 10-degree steering angle and a turning radius inside of 19.4 feet, enhancing its operational flexibility. The water spray tank capacity is 220.4 gallons to keep drums moist, preventing asphalt adhesion during compaction. Its wheelbase spans 141.8 inches and track width is 6 feet, supporting the roller's weight distribution. The HAMM HD+ 90i PH VV combines advanced hydraulic and engine technology to deliver powerful, energy-efficient compaction, ideal for asphalt and soil compaction projects requiring consistent, high-quality results.
