HAMM HD 12 VO (VIB/OSC) STATIC SMOOTH DRUM ROLLER

The HAMM HD 12 VO is a compact tandem smooth drum roller designed for efficient soil and asphalt compaction with both vibration and oscillation capabilities. It features a 47.2-inch wide front and rear smooth drums, each 28.3 inches in diameter and 0.6 inches thick, providing even and consistent compaction. The front drum operates with dual vibration frequencies of 52 Hz and 67 Hz (3,120 and 4,020 vpm), delivering centrifugal forces up to approximately 8,550 lbf, while the rear drum oscillates at frequencies of 30 and 39 Hz with oscillation forces of about 5,170 and 8,992 lbf, respectively, and an oscillation angle of 8 degrees to enhance ground contact and compaction quality. Powered by a Kubota diesel engine (D1503 or D1703), the roller provides 30.7 gross horsepower with a fuel capacity of 11.1 gallons, allowing for sustained operation. Key dimensions include a total operating width of 51.6 inches, an overall length near 99.6 inches, a wheelbase of 66.9 inches, and a ground clearance of 22.45 inches. The machine has a maximum operating weight up to approximately 7,650 lb, ensuring stability during compaction tasks. Its articulated steering offers an inside turning radius of about 93.3 inches, promoting maneuverability on site. The HAMM HD 12 VO also integrates a pressure water spray system with a 47.6-gallon tank to prevent drum sticking and enhance surface finish. Designed with an ergonomic, vibration-isolated operator platform and a clear view of the drum edges, it supports precision operation and user comfort in a variety of compacting applications.
