INGERSOLL RAND SD-122DX STATIC SMOOTH DRUM ROLLER

The Ingersoll Rand SD-122DX is a high-performance smooth drum vibratory roller designed for efficient soil and aggregate compaction. Powered by a 156 hp Cummins QSB5.9-30T turbocharged diesel engine, it delivers robust compaction force with a high centrifugal force of 63,171 lbs and low centrifugal force of 46,311 lbs. The roller features an 84.1-inch wide smooth steel drum with a diameter of 58.7 inches, providing uniform compaction over large surface areas. Operating at vibration frequencies between 1,225 and 2,025 vibrations per minute (vpm), with nominal vibration amplitudes of 0.1 inch, the SD-122DX offers precise control over compaction intensity. It includes dual vibration frequency settings at 30.9 and 33.8 Hz to suit various ground conditions. The total operating weight is approximately 26,460 lbs, ensuring strong downward force for dense compaction. Key operational dimensions include a ground clearance of 19.1 inches, a turning radius of 136 inches, and an overall length of 19.4 feet, combined with a 90-inch operating width for optimized maneuverability and site coverage. The hydraulic system holds 22.2 gallons of fluid, supporting smooth machine functionality, while a 67.9-gallon fuel tank ensures extended operating periods. Mounted on 23.1x26-18PR R3 tires, the roller balances traction and mobility for construction site versatility. This model is well-suited for roadwork, large construction projects, and general compaction tasks requiring high force and consistent smooth drum performance.
