The Sakai SW320 is a static smooth drum roller designed for efficient soil and asphalt compaction, featuring a smooth drum of 27.6 inches in diameter that delivers a centrifugal force of approximately 7,059 lbs at a vibration frequency of 4,000 vibrations per minute (vpm). Powered by a Kubota D1703 diesel engine, this 3-cylinder, vertically mounted, water-cooled unit generates 34.1 horsepower at 2,800 rpm, combining reliability and efficient fuel consumption with a 13.3-gallon fuel tank capacity. The roller weighs around 6,327 lbs and offers an operating width of 47 inches for broad compaction coverage. Its design includes a ground clearance of 9.9 inches and a compact overall footprint with an 8.7-foot length, 4.4-foot width, and 5.8-foot height to the top of the cab, easing maneuverability in varied construction environments. The machine has a tight inside turning radius of 103 inches supported by a 6.4-inch wheelbase, facilitating effective navigation around job sites. Additional features include independent vibration controls and superior shock isolation for operator comfort, along with a 12-volt operating system. The SW320 achieves a maximum speed of 7.5 mph, suitable for various compaction projects requiring smooth, consistent surface finishes. Its robust hydrostatic drive system and chamfered drum edges ensure efficient, precise compaction with excellent curb clearance and drum visibility, making it a versatile choice for contractors.
