SAKAI SW770HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW770HF is a high-frequency vibratory tandem smooth drum roller designed for efficient asphalt compaction. It features a 67-inch (1.7 m) drum width and delivers a high-frequency vibration range of 2,500 to 4,000 vpm (42–67 Hz), enabling rapid density achievement and a smooth hot mix asphalt mat. The machine is powered by an Isuzu 4JJ1XDIA Tier 3 diesel engine, a 3.0 L, turbocharged, intercooled inline-four unit that provides reliable performance and maintains power at higher elevations. With an operating weight of 23,810 lb (10,800 kg), the SW770HF offers a front axle load of 11,465 lb and a rear axle load of 12,345 lb, delivering strong compaction force and stability. It has a maximum travel speed of 14 km/h (8.7 mph) and a wheelbase of 141.7 in (3.6 m), providing good maneuverability on job sites. The articulated center-pin joint ensures excellent steering response and a tight turning radius, while the full-coverage operator station provides excellent visibility over the drums, edges, and sprinkler nozzles. The roller includes a dual water pump system, anti-clog sprinkler package with triple filtration, and automatic water shutoff in neutral for improved reliability and ease of maintenance. Designed for high productivity and operator comfort, the SW770HF is a robust solution for asphalt paving and road construction applications.
