INGERSOLL RAND DD138HFA STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD138HFA is a heavy-duty vibratory smooth drum roller designed for efficient soil and asphalt compaction. It features a 92-inch wide smooth tandem drum with a diameter of 4.5 inches, delivering a high centrifugal force of 41,715 lbs and a low centrifugal force of 36,685 lbs, both at a nominal amplitude of 0.1 inches. The drum vibrates at frequencies ranging between 2,700 and 4,000 vibrations per minute, with additional vibration frequency settings at 45 and 66.7 vibrations per minute, optimizing compaction performance across various materials. Powered by a robust Cummins B5.9-173 turbocharged and charge air-cooled six-cylinder engine, this machine produces 173 horsepower (129 kW), ensuring reliable and consistent power output. It operates on a 12-volt electrical system, supported by a 95-amp alternator. The roller has a fuel capacity of 68.5 gallons and a hydraulic system fluid capacity of 36.5 gallons, balancing operational endurance and hydraulic efficiency. The maximum travel speed is 6.6 mph (10 kph), suitable for controlled, effective compaction. With an operating weight of 30,325 lbs and a turning radius inside of about 179.6 inches, the DD138HFA maintains stability and maneuverability on job sites. The machine’s height to the top of the cab measures approximately 10.4 feet, and its overall length is 19.5 feet, making it a sizable yet agile compactor for large-scale construction and roadwork projects. This combination of power, compaction force, and precision makes the DD138HFA ideal for demanding compaction tasks.
