SAKAI SW990-1 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW990-1 is a heavy-duty static smooth drum roller designed for efficient compaction in asphalt and soil applications. It features dual smooth drums, each 84 inches wide, delivering extensive ground coverage. The machine has a total operating weight of 30,800 lbs, balanced nearly evenly between the front drum (15,235 lbs) and rear drum (15,565 lbs), providing optimal soil or asphalt compaction pressure. Powered by a Cummins engine, the roller supports a vibration frequency range from 42 to 67 vpm, with a centrifugal force varying between 15,285 lbs (low) and 41,590 lbs (high), enabling high-efficiency compaction and precise control over soil density. The low amplitude vibration is 0.013 inches, ideal for achieving smooth finishes without damaging surfaces. The machine offers a tight inside turning radius of 14.3 inches, facilitating maneuverability in confined spaces. Its spray system holds 318 gallons, supporting continuous drum wetting to prevent material buildup and ensure smooth operation. The operating width is 7.5 feet, making it suitable for a variety of paving and compaction tasks. This model combines robust performance and durability, aimed at large-scale construction projects requiring powerful, consistent compaction with manageable machine dimensions and operational efficiency.
