SAKAI SW770ND STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW770ND static smooth drum roller is a heavy-duty compaction machine designed for efficient asphalt and soil compaction. It features a 67-inch (170 cm) wide drum with a vibration frequency of 50 vibrations per minute (vpm), allowing for stable and uniform compaction performance. The roller is powered by a reliable Isuzu engine, delivering robust power to handle demanding construction tasks. Its operating specifications include an overall length of 194.9 inches, width of 73.2 inches, and a height of 115.7 inches, making it a sizable machine suitable for large-area coverage. The wheelbase spans 141.7 inches, supporting maneuverability in varied terrain. The SW770ND has an operating weight of 24,955 pounds, distributed between 12,035 pounds on the front axle and 12,920 pounds on the rear axle, ensuring optimal ground pressure for effective compaction control. This model features an articulated center-pin joint and patented rubber isolators for durability and operator comfort. The vibration system can be switched between oscillatory and circular modes, enabling adjustment based on compaction requirements — oscillatory mode is ideal for thin layers, while circular vibration suits thicker layer compaction, enhancing versatility and efficiency. This combination of engineering features supports smooth, consistent mat surfaces, making the SW770ND well suited for road construction and pavement projects where quality, performance, and reliability are critical.
