INGERSOLL RAND DD-70HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD-70HF Static Smooth Drum Roller is a robust compaction machine designed for soil and asphalt applications. It features a ground clearance of 22 inches and an overall length of 14.5 feet, with a top cab height of 9.2 feet, providing excellent visibility and maneuverability. Equipped with a 64-inch wide smooth drum, the roller generates a high centrifugal force of 21,080 lbs and a low centrifugal force of 7,820 lbs, both at a vibration frequency of up to 4,000 vibrations per minute (vpm). The nominal amplitude remains consistent at 0.1 inches across both high and low settings, optimizing compaction effectiveness. Powered by a naturally aspirated Cummins 4-cylinder 4B 3.9 engine producing 80 hp (60 kW), the unit balances power and efficiency. The hydraulic system holds 17 gallons of fluid, with a fuel capacity of 37 gallons supporting extended operation. The hydraulic and electrical systems operate at 12 volts with a 95-amp alternator supply. The machine’s maximum speed reaches 6.6 mph, and its operating weight is approximately 14,895 lbs, which contributes to effective compaction force without sacrificing mobility. The inside and outside turning radius are both 189 inches, offering good maneuverability for site conditions. This double drum roller particularly excels in high-frequency vibration compaction, ideal for granular and mixed soils, providing a balance of weight, power, and vibration to meet various job site requirements efficiently.
