INGERSOLL RAND DD-90HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD-90HF is a heavy-duty vibratory smooth drum roller designed for efficient asphalt compaction. It features a dual 66-inch wide and 48-inch diameter drums providing centrifugal forces of 38,430 lbs on high and 16,030 lbs on low settings, with a constant amplitude of 0.1 inches for both high and low modes. The vibration frequencies operate at 63.3 and 47.5 vibrations per minute, enhancing compaction smoothness and effectiveness. Powered by a turbocharged 4-cylinder Cummins B3.9-C diesel engine delivering 110 hp (82 kW), the unit provides robust performance with reliable torque and fuel efficiency. The engine's specifications include a hydraulic fluid capacity of 35 gallons and a fuel capacity of 45 gallons, supporting prolonged operation. The roller has a maximum travel speed of 8.7 mph (13 kph) and an outside turning radius of 206 inches, allowing for maneuverability on job sites. Operating weight is approximately 21,705 lbs with a height to the top of the cab of 9.3 feet and an overall length of 16.5 feet. The electrical system runs on 12 volts with a 95-amp alternator supplying power for operational components. The DD-90HF is engineered for optimal operator comfort with a rotating station and adjustable seat, and advanced vibration controls that ensure consistent compaction quality across various asphalt mixes and lift thicknesses, making it suitable for high-production paving projects.
