HAMM HW 90B 12T STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HW 90B 12T is a static smooth drum roller engineered for compaction applications requiring consistent, non-vibrating pressure. This three-wheel configuration features an 79-inch drum width and a compact 154-inch inside turning radius, enabling precise maneuverability in confined work areas. The machine weighs 12.6 tons and maintains a static line load of 60.2 kg/cm, delivering uniform ground contact for optimal compaction results. Powered by a Deutz BF4L2011 turbocharged diesel engine producing 53.5 kW (71.7 hp), the roller achieves a maximum travel speed of 12.3 km/h. The static vibration frequency eliminates dynamic compaction forces, making it ideal for finishing work on asphalt and aggregate surfaces where vibration could cause material displacement. Transport dimensions are 4.89 meters in length, 2.66 meters in width, and 3.22 meters in height, with drums measuring 1.55 meters in diameter. The roller incorporates hydrostatic traction drive technology for smooth operation and precise speed control. Its ergonomic design includes two operator seats, a pressurized sprinkler system for dust control, and a 400-liter water tank enabling extended operating periods. The HW 90B 12T delivers professional-grade compaction performance suitable for highway construction, parking lot finishing, and other applications demanding smooth, static rolling action without vibration-induced disturbance.
