The Ingersoll Rand DD-118HF is a high-frequency vibratory smooth drum roller engineered for efficient compaction on asphalt and granular soils. Powered by a turbocharged Cummins B3.9-C125 engine delivering 125 hp (93 kW), it combines robust power with a 53.1-gallon fuel capacity and hydraulic system fluid capacity of 34.9 gallons. The machine has an operating weight of approximately 27,260 lbs and features a drum width of 87 inches and a diameter of 55.2 inches, providing extensive compaction coverage. Its high centrifugal force reaches 42,669 lbs on the high setting and 22,976 lbs on low, with a nominal amplitude constant at 0.1 inches for both ranges, and vibration frequencies of 3400 and 56.7 vpm respectively, optimizing soil densification with fewer passes. The DD-118HF has dimensions suited for versatile job site application: 19.7 feet overall length, 7.3 feet width, a cab height of 10.4 feet, and 20.1 inches ground clearance, with an inside turning radius of 148.5 inches facilitating tight maneuverability. The wheelbase measures 11.7 feet, enabling stable operation. Electrical systems operate at 12 volts with a 95-amp alternator. Its design supports faster rolling speeds and maximizes productivity on large-scale paving projects, making it ideal for highway, road, and commercial site compaction tasks where smooth finish and optimal soil density are required. Safety and operator comfort are enhanced by its cab design and operational controls.
