The Ingersoll Rand DD-14S is a compact vibratory smooth drum roller engineered for efficient soil and asphalt compaction. It features a tandem smooth drum design with a drum width of 35.4 inches and a diameter of 22.1 inches, providing an operating width of 40.1 inches. The roller’s dual vibratory system operates at 4000 vibrations per minute (vpm) with a frequency of 66.7 Hz and delivers a centrifugal force of 3,507 pounds at a nominal amplitude of 0.1 inches, optimizing compaction efficiency. Powered by a reliable Kubota D722 engine producing approximately 16.9 horsepower, the DD-14S operates with a hydraulic transmission and maintains a maximum speed of 5 mph. The machine’s compact footprint includes an overall length of 6.68 feet, width of 3.24 feet, and a height to the top of the cab at 7.36 feet, with a turning radius of 108 inches inside and outside, allowing for excellent maneuverability in confined spaces. The DD-14S weighs 3,172.5 pounds and is equipped with a fuel capacity of 7.8 gallons and a hydraulic fluid capacity of 9.1 gallons. Electrical systems run on 12 volts with a 40-amp alternator. The wheelbase measures 4.6 feet, reinforcing stability during compaction operations. This model is suited for small to medium compaction tasks requiring precise vibration control and smooth surface finishes, making it ideal for contractors working on sidewalks, driveways, and patching applications. The rugged design and quality Kubota engine ensure dependable performance and durability in varied construction environments.
