HAMM HD+ 120I VO STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 120i VO is a tandem static smooth drum roller designed for high-performance asphalt compaction. It features a 78-inch wide smooth, non-split drum with a 55.2-inch diameter and 0.8-inch thickness, delivering a static linear load of 177 pounds per inch. The roller is equipped with a vibration and oscillation drum system, providing selectable high and low centrifugal forces of 38,892 lbs and 21,356.9 lbs, respectively, with nominal amplitude of 0.1 inch and vibration frequencies of 40 and 50 vpm. The rear oscillation drum generates an oscillation force of 39,341.6 lbs at 36 vpm with a tangential amplitude of 0.1 inch and an oscillating angle of 10 degrees, enabling efficient, high-quality compaction with reduced dynamic loads. Powered by a DEUTZ TCD 4.1 L4 four-cylinder diesel engine, the machine produces 154.3 hp (115 kW) at 2,300 rpm and meets EPA Tier 4 emissions standards. It has an operating weight of 30,137.2 lbs, a fuel capacity of 68.7 gallons, a DEF tank capacity of 5.3 gallons, and a 302.5-gallon water spray tank. With an overall length of 208.7 inches, width of 7.1 feet, and a ground clearance of 35.5 inches, the HD+ 120i VO offers excellent maneuverability with an inside turning radius of 20.7 feet and a maximum speed of 3.8 mph.
