Top 100: Eight-Amplitude Flexibility

September 28, 2010

Ingersoll-Rand DD-125HFThe Ingersoll Rand DD-125HF is designed, says the manufacturer, to keep up with pavers moving at faster placement speeds, without the need for additional compactors on the job. With its patented eight-amplitude system, the DD-125 provides a wide range of vibration parameters for maximum versatility. A patented impact meter on the unit indicates the relationship between vibration frequency and rolling speed, thus providing a measurement of drum impacts per foot. An easy-to-read gauge allows the operator to select optimal impact spacing for a given roller speed. Weighing 28,043 pounds, the unit produces a maximum centrifugal force of 35,190 pounds. Estimated list price: $125,000 to $130,000.
