SAKAI SW850ND-II (OSC/VIBE) STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW850ND-II (OSC/VIBE) is a high-performance static smooth drum roller designed for versatile compaction tasks, including asphalt and base material projects. It features a 79-inch wide drum with a diameter of 54 inches, enabling a substantial compaction footprint. The roller operates with a vibration frequency of 2,820 vibrations per minute (47 Hz) and a nominal amplitude range of 0.022 to 0.024 inches, generating a centrifugal force up to 38,440 lbs (171 kN) for effective soil and asphalt compaction. Powered by a robust Deutz engine delivering 95 kW (127.38 hp) with a 4.038-liter displacement, the SW850ND-II combines power and precision to optimize compaction efficiency. The machine weighs 13.37 tons (29,475.98 lbs) and has transport dimensions of 5.82 meters length, 2.205 meters width, and 2.325 meters height, ensuring manageable mobility between sites. Its oscillation and vibration capabilities (OSC/VIBE) enhance its suitability for no-vibration and vibrating compaction applications, particularly where structural integrity is critical, offering an adaptable solution for various paving requirements. This model’s combination of extensive drum width, powerful vibration force, and reliable engine configuration makes it a preferred choice for contractors needing consistent and high-quality ground compaction.
