INGERSOLL RAND DD12S STATIC SMOOTH DRUM ROLLER

The Ingersoll Rand DD12S is a compact vibratory smooth drum roller designed for efficient soil compaction in a variety of construction and infrastructure applications. It features a robust 16.1 hp (12 kW) engine with a 34.8 cubic inch displacement, providing reliable power for consistent performance. The roller’s smooth drum is 35.5 inches wide and 21.9 inches in diameter, delivering a high centrifugal force of approximately 3,305 lbs to achieve effective compaction. With a nominal amplitude of 0.1 inches and a vibration frequency of 66.7 vibrations per minute, the DD12S optimizes compaction energy for better soil density with fewer passes. The unit has a ground clearance of 13.3 inches and an overall length of 6.7 feet, making it maneuverable in tight spaces. Standing 7.4 feet tall to the top of the cab and with an operating weight of about 2,903.5 lbs, this model balances portability with stability. It operates on a 12-volt electrical system supported by a 15-amp alternator, with a fuel capacity of 7.1 gallons and a hydraulic fluid capacity of 9 gallons, supporting extended use on site. The wheelbase measures 4.6 feet, giving the machine solid traction and control. These specifications make the Ingersoll Rand DD12S ideal for compacting granular and mixed soils in roadwork, utilities, and paving projects where precise, smooth compaction is required, especially in confined or urban job sites.
