VOLVO DD90 STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD90 static smooth drum roller is a high-performance compaction machine designed for large-scale asphalt and road construction projects. It features a 66-inch-wide and 48-inch-diameter drum that delivers powerful vibratory compaction with frequencies ranging from 1,850 to 2,500 vibrations per minute (vpm), providing centrifugal forces between 5,840 and 26,000 pounds. Powered by a Cummins engine producing 110 horsepower, the DD90 has an operating weight of 21,820 pounds and a fuel capacity of 45 gallons, supporting efficient and extended operation. The hydraulic system holds 35 gallons of fluid, and the roller operates on a 12-volt electrical system with a 95-amp alternator. Its compact dimensions, including an overall width of 5.5 feet and an inside turning radius of 18 feet, enable effective maneuverability on job sites. The maximum speed of the DD90 is 7.4 miles per hour, allowing for controlled and precise compaction. The machine’s nominal amplitude is 0.1 inches in both high and low settings, ensuring uniform soil and asphalt compaction. At a height of 9.25 feet to the top of the cab, it ensures good operator visibility and safety. The DD90’s hydrostatic drive system provides smooth, responsive steering and propulsion, making it suitable for varied pavement conditions and large-area compaction tasks with excellent reliability and productivity.
