STONE DD90HF STATIC SMOOTH DRUM ROLLER

The Stone DD90HF Static Smooth Drum Roller is a high-performance compactor designed for heavy-duty asphalt and soil compaction projects. It features a 66-inch wide, 48-inch diameter smooth drum for effective surface leveling and consolidation. The equipment has an inside turning radius of 140 inches and an operating width of 75.2 inches, enabling maneuverability in various job site conditions. Powered by a Cummins QSB 4.5 Tier 3 turbocharged and intercooled engine delivering approximately 140 HP at 2000 RPM, it ensures reliable and efficient operation. The compactor employs a dual-frequency vibratory system with a high vibration frequency of 63.3 Hz (3,800 vpm) and a nominal amplitude of 0.1 inches, which provides optimal compaction force for asphalt and granular materials. The operating weight is about 21,705 lbs, balancing static weight for effective ground pressure without compromising mobility. Fuel capacity is 45 gallons, supporting extended work periods, paired with a 35-gallon hydraulic fluid system. The hydraulic closed-loop system drives both drums independently, enhancing traction and compaction uniformity. Max travel speed reaches up to 8.7 mph, ensuring efficient site coverage. Electrical systems operate at 12V with a 95-amp alternator. The drum shell thickness is 0.75 inches for durability. Offering centrifugal forces of up to 38,430 lbs on high amplitude, the DD90HF is engineered for highway and heavy paving applications, combining robust power, advanced vibration control, and operational efficiency in one versatile machine. This makes it suitable for large-scale projects requiring consistent and thorough compaction.
