INGERSOLL RAND DD28HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD28HF is a vibratory smooth drum roller designed for efficient soil and asphalt compaction. It features a 49.3-inch wide and 28.9-inch diameter smooth drum with a high centrifugal force of 8,205.6 lbs, delivering strong compaction performance. The drum vibrates at a frequency of 70 vibrations per minute with a nominal amplitude of 0.1 inches, optimizing consolidation of materials. Powered by a V2203M engine, the roller produces 44 horsepower (33 kW) enabling a maximum speed of 6.3 mph (10 kph). The machine has substantial ground clearance of 19.1 inches and a wheelbase of 5.7 inches, with an overall length of 8.5 feet and width of 4.5 feet, making it maneuverable for various job sites. The hydraulic system carries 22.5 gallons of fluid and the fuel tank capacity is 18 gallons, supporting extended operation periods. An alternator rated at 40 amps supplies electrical power, with the system operating at 12 volts. The machine’s total operating weight is approximately 6,751 lbs, providing necessary mass for effective compaction without sacrificing transportability. The operator cab height reaches 8.3 feet, ensuring visibility and control during operation. This model’s balance of power, vibration technology, and dimensions make it suitable for medium-scale compaction tasks in road construction and site preparation.
