INGERSOLL RAND SD-122F STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand SD-122F is a heavy-duty smooth drum roller engineered for efficient soil compaction in large-scale construction projects. It features an 84.1-inch wide, 59.1-inch diameter drum equipped with 120 pads, each 5 inches tall, delivering substantial compaction force with centrifugal forces of 65,869 lbs on high and 64,071 lbs on low settings. The drum operates at vibration frequencies ranging from 1,225 to 2,025 vpm (approximately 27.6 to 33.8 Hz) with a nominal amplitude of 0.1 inches, ensuring consistent and deep soil compaction. Powered by a turbocharged Cummins engine rated at 156 hp, the SD-122F offers reliable power combined with a two-speed hydrostatic transmission enabling maximum speeds up to 7.9 mph. It has a ground clearance of 1.6 feet, an overall length of 19.4 feet (excluding blade) and a turning radius of 136 inches for maneuverability on job sites. The machine’s operating width is 90 inches supported on durable 23.1x26 8PR R1 tires, designed for robust traction and stability. Additional systems include a 95-amp alternator, 12-volt electrical operating voltage, and hydraulic fluid capacity of 22 gallons, supporting operational efficiency. The roller weighs approximately 28,235 pounds and has a fuel capacity of 68 gallons, allowing for extended operation without frequent refueling. Ideal for compaction of asphalt, granular and cohesive soils in highway, airport, and large commercial site construction, the SD-122F offers a balance of power, precision, and durability for demanding compaction needs.
