VOLVO SD122D TF SERIES STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo SD122D TF Series is a heavy-duty smooth drum roller designed for efficient soil and asphalt compaction. It features an 84-inch (2.13 m) wide drum with a vibration frequency range of 1,850 to 2,025 vibrations per minute (30.8 to 33.8 Hz), delivering centrifugal forces of 63,171 lbf (281 kN) on high and 46,311 lbf (206 kN) on low settings. The nominal amplitude varies between 0.075 in (1.90 mm) at high and 0.046 in (1.17 mm) at low amplitude. Powered by a Cummins engine producing 162 hp (119 kW), the roller weighs approximately 26,396 lbs (11,973 kg). The SD122D offers an operating width of 90 inches and an inside turning radius of 136 inches, enabling good maneuverability on job sites. Its transport dimensions are about 19.36 ft (5.9 m) in length, 7.5 ft (2.29 m) in width, and 10.14 ft (3.09 m) in height. The model was produced between 2007 and 2012. This roller is suitable for medium to large-scale compaction projects, where high frequency and amplitude variable vibrations enhance soil density and surface smoothness. Its robust Cummins powertrain and precise vibration controls help optimize compaction efficiency on various materials, making it a reliable choice for infrastructure and road construction applications.
