HAMM HD+ 120I VV HF STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 120I VV HF is a high-performance smooth drum roller engineered for efficient compaction tasks. It features a tandem roller design with two vibrating, smooth, non-split drums, each 78 inches wide and 55.12 inches in diameter, providing an operating width of 84 inches. The drums deliver vibration frequencies of 45/67 VPM, with a nominal amplitude ranging from 0.01 to 0.03 inches and centrifugal forces up to 38,925 lbs, ensuring superior soil and asphalt compaction. Powered by a robust Deutz TCD 4.1 L4 turbocharged, water-cooled diesel engine, this model outputs 154.1 horsepower at 2300 RPM. The engine meets stringent EU Stage V and EPA Tier 4 emissions standards, featuring advanced aftertreatment systems including SCR and particulate filters for low emissions and fuel-efficient operation. The fuel tank capacity is 68.68 gallons, supported by a large 302.48-gallon water tank for drum wetting. The roller weighs approximately 27,110 lbs, with a turning radius inside of 235 inches and a wheelbase of 149.61 inches, balancing maneuverability with stability. Its static linear drum loads are approximately 174.74 lbs/in at the front and 173.03 lbs/in at the rear, optimizing ground pressure distribution. Additional specifications include ground clearance of 35.43 inches on the sides and 13.39 inches at the center, total machine length around 204.72 inches, and overall height of 117.32 inches, making it suitable for diverse roadbuilding and surface consolidation applications with excellent operator visibility and control.
