HAMM HD+ 120VO STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 120VO is a high-performance smooth drum roller designed for efficient compaction in road construction and earthworks. It features a 78-inch wide drum with a diameter of 55.2 inches and a thickness of 0.8 inches, providing a substantial contact area for effective soil and asphalt compaction. The machine’s operating width is 83 inches, and it has a compact turning radius of 208 inches for enhanced maneuverability on site. Powered by a DEUTZ TCD 2012 L04 2V engine, delivering 134.2 horsepower, this roller balances power and fuel efficiency with a fuel capacity of 47.6 gallons. The HD+ 120VO operates at a maximum speed of 3.8 mph, with vibration frequencies ranging between 40 and 50 vibrations per minute (vpm). It employs vibration and oscillation drum technology, which optimizes compaction by transmitting energy both vertically and tangentially, improving homogeneity and quality of compaction. The machine's centrifugal force reaches up to 35,744.7 pounds in high amplitude mode, with dual amplitude settings of 0.1 inches nominal amplitude. The oscillation frequency of the rear drum is 36 Hz, with an oscillation force of 170 kN, enhancing surface smoothness without material displacement. Additional features include a robust operating weight of approximately 29,740 pounds with the cabin, a water spray tank capacity of 306.5 gallons for dust suppression, and a steering angle of 10 degrees combined with +/- 10 degrees oscillation angle for smooth operation on uneven terrain. Overall dimensions are 196.86 inches in length, 7.04 feet wide, and 10.01 feet tall to the top of the cab, making it a versatile and efficient compaction machine for various construction applications.
