INGERSOLL RAND DD-112HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD-112HF is a robust vibratory smooth drum roller designed for effective asphalt compaction. Powered by a Cummins B3.9 4-cylinder diesel engine, it delivers 125 horsepower to ensure strong performance on job sites. This model features dual drum widths of approximately 78.7 to 78.8 inches and a drum diameter near 55.1 to 55.2 inches, providing substantial surface coverage. It operates with a dual-amplitude vibration system offering high frequency at 4,200 vibrations per minute (vpm) and low frequency at 3,000 vpm, with nominal amplitudes of 0.032 inches for high and 0.013 inches for low settings. The machine generates centrifugal forces of up to 42,070 pounds in high mode and 33,090 pounds in low mode, which contributes to efficient compaction. The DD-112HF has an operating weight of around 27,670 pounds, distributed between the front and rear drums. It has a turning radius of 148.5 inches (inside to drum edge), an operating width of 87 inches, and a ground clearance of 20.08 inches. The overall dimensions include a length of 19.67 feet, width about 7.26 feet, and height to ROPS/FOPS of 124.4 inches. The roller is suited for asphalt construction projects requiring versatile compaction with dual-amplitude vibration control and strong centrifugal force, backed by a reliable Cummins engine.
