INGERSOLL RAND DD118HFA STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD118HFA is a high-performance vibratory smooth drum roller designed for superior soil compaction. It features a robust Cummins B3.9-C125 inline 4-cylinder diesel engine delivering 125 hp (93 kW) at 2200 RPM, optimized for industrial applications with turbocharged aspiration and electronic fuel system management. The engine provides reliable power with a fuel capacity of 53.1 gallons and a 12-volt electrical system supported by a 95-amp alternator, ensuring consistent operation. The roller’s drum has a diameter of 55.2 inches and operates with a centrifugal force of 42,062 lbs at high vibration and 33,092 lbs at low vibration, both with a nominal amplitude of 0.1 inches. Its vibration frequency ranges between 3000 and 4200 vibrations per minute, enabling effective soil densification. The machine measures approximately 19.7 feet in length, 7.3 feet in width, with an operating width of 87 inches, and stands 10.4 feet tall to the top of the cab. It offers a ground clearance of 20.1 inches and an inside turning radius of 148.5 inches for maneuverability on job sites. Weighing 27,260 lbs, it achieves a maximum speed of 6.6 mph, balancing power and mobility for effective compaction in road construction and other heavy-duty applications. The DD118HFA’s engineering focuses on combining power, precision vibration settings, and operator comfort to maximize productivity and compaction quality.
