HAMM HD+ 120I VV STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 120i VV is a high-performance smooth drum roller designed for efficient compaction in road construction and maintenance. It features two vibration drums, each 78 inches wide, with a drum diameter of 55.2 inches and thickness of 0.8 inches, providing strong centrifugal forces of 38,892 lbs (high) and 21,356.9 lbs (low) to achieve optimal soil compaction. The drums operate at a vibration frequency of 40 to 50 vibrations per minute, with a nominal amplitude of 0.1 inches for both high and low settings. Powered by a Deutz TCD 4.1 L4 engine, the roller delivers 154.3 hp (115 kW) from its 4-cylinder diesel powerplant, supported by a 68.7-gallon fuel capacity. Its robust design supports a maximum operating weight near 29,520 lbs, with the ability to maintain a max speed of 3.8 mph (5 kph). The machine features a ground clearance of 35.5 inches and an overall length of 208.7 inches, width of 7.1 feet, and cab height of 9.8 feet, offering good maneuverability with a wheelbase of 153.6 inches and a steering angle of 10 degrees. The HD+ 120i VV includes a large 302.5-gallon water spray tank to support drum wetting for effective dust control during compaction. Its hydrostatic drive and advanced electronic machine management system (HAMMTRONIC) optimize fuel efficiency, engine speed, drive torque distribution, and vibration control, enhancing performance, safety, and operator comfort. Its 3-point articulation design enables smooth steering and excellent driving stability on job sites. This roller is ideal for large-scale, precise compaction operations requiring consistent and efficient soil and asphalt compaction.
