INGERSOLL RAND DD-138HF STATIC SMOOTH DRUM ROLLER

The Ingersoll Rand DD-138HF is a heavy-duty smooth drum vibratory roller designed for efficient asphalt and soil compaction. It features dual smooth drums with a diameter of 55.2 inches and an operating width of 92 inches, providing uniform compaction. The roller generates high centrifugal forces of 42,264 lbs on high vibration mode and 21,829 lbs on low, both with a nominal amplitude of 0.1 inches, and vibration frequencies of 3,200 vpm and 53.3 vpm respectively, enabling deep and effective soil consolidation. Powered by a Cummins B5.9-173 6-cylinder, turbocharged, charge-air cooled diesel engine producing 173 hp (129 kW), the machine delivers reliable power and high torque for demanding applications. The engine supports a 12-volt electrical system with a 95-amp alternator. It holds a fuel capacity of 68.5 gallons and a hydraulic fluid capacity of 36.5 gallons, supporting extended operation in the field. The roller's dimensions include a ground clearance of 20.1 inches, an overall width of 7.7 feet, length of 19.7 feet, height to top of the cab of 10.5 feet, a wheelbase of 11.7 feet, and an inside turning radius of 179.6 inches, offering maneuverability in tight job sites. Weighing 28,726 lbs, it achieves a maximum speed of 6.6 mph, balancing transport efficiency with operating stability. The DD-138HF includes operator features mindful of comfort and safety and is built for durability in road construction and asphalt paving projects, making it an industry-standard in vibratory smooth drum rollers.
