INGERSOLL RAND DD-118HA STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD-118HA is a vibratory smooth drum roller engineered for heavy compaction tasks. It features a **78.8-inch wide steel drum** with a diameter of approximately 55.2 inches, operating at a **vibration frequency of 3000 vpm (50 Hz)**. The machine delivers substantial compaction force, with a **centrifugal force of 42,070 lbs in high mode and 16,880 lbs in low mode**, both at a nominal amplitude of 0.1 inches. Powered by a **Cummins B3.9-C125 turbocharged diesel engine**, this inline 4-cylinder, 3.9-liter engine produces **125 horsepower at 2200 RPM**, providing reliable and efficient power for demanding construction applications. The DD-118HA has an **operating width of 87 inches**, an overall length of 19.67 feet, width of 7.26 feet, and a height to the top of the cab of 10.37 feet, ensuring good maneuverability and operator visibility. Its **inside turning radius is 148.5 inches**, allowing for efficient operation in confined spaces. The roller’s operating weight is approximately **27,260 lbs**, supported by a fuel capacity of 53.1 gallons and hydraulic fluid capacity of 34.9 gallons, ensuring extended work periods between refills. Additional features include 12 V electrical system and a 328-gallon water tank to aid drum surface moisture control during compaction. This robust, versatile roller is ideal for asphalt and granular base compaction, offering high productivity with enhanced vibration capabilities and substantial operating weight for deep compaction in road construction and large paving projects.
