INGERSOLL RAND DD158HFA STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD158HFA is a heavy-duty vibratory smooth drum roller designed for efficient soil compaction. It features a 59-inch diameter drum capable of exerting a centrifugal force of up to 44,910 lbs at high settings and 38,280 lbs at low settings, both with a nominal amplitude of 0.1 inch. The drum vibration frequency ranges from 2,500 to 3,400 vibrations per minute, with selectable vibration frequencies of 41.7 Hz and 56.7 Hz, enabling optimized compaction for various soil types. Powered by a Cummins QSB 5.9-C turbocharged, charge air-cooled inline 6-cylinder diesel engine, the roller delivers a net power output of 185 hp (138 kW). The machine operates with a hydrostatic two-speed transmission allowing a maximum travel speed of 6.6 mph (10 kph). It has an operating weight of 33,810 lbs and a width of 92 inches, with an overall length of 12.3 feet and a cab height of 10.5 feet. The fuel tank capacity of 68 gallons and a 35-gallon hydraulic fluid reservoir support long operation periods. Electrical systems run at 12 volts with a 95-amp alternator supply. Designed for robust compaction tasks, the DD158HFA combines powerful vibration parameters with reliable Cummins engine performance and strong hydraulic systems, making it suitable for road construction and earthwork projects requiring consistent, high-quality soil compaction.
