SAKAI SW320-I STATIC SMOOTH DRUM ROLLER

The Sakai SW320-I is a high-performance smooth drum roller designed for efficient asphalt and soil compaction. It features a 47-inch wide drum with a diameter of 27.6 inches, delivering a vibration frequency of approximately 66.7 vibrations per minute (vpm), generating a centrifugal force of around 7,055 lbs for effective compaction. Powered by a Kubota D1703-M-ET01 vertical, water-cooled, 4-cycle diesel engine, it produces 34.1 horsepower with a displacement of 1.647 liters (100.5 cubic inches), ensuring reliable power and fuel efficiency. The roller's operating weight is about 6,320 to 6,720 lbs, balancing maneuverability and ground contact for optimal rolling performance. It has an overall width of approximately 4.3 feet (around 4 ft 4 in), a compact inside turning radius near 8.6 to 9 inches, and a comfortable working height of roughly 5.75 feet to the top of the cab. The SW320-I incorporates advanced features including independent drum vibration control, counter-rotating eccentric weights, hydrostatic dual drum drive, and multi-filtered spray system to maintain drum cleanliness. The unit is equipped with a heavy-duty center hitch, excellent curb clearance, and vibration controls accessible from the instrument panel. Operator comfort and safety are enhanced by an open roll-over protective structure (ROPS), seat belt, and front lighting. Its maximum travel speed reaches 7.5 mph, fueled by a 13.3-gallon capacity tank with 12V electrical system, making it well-suited for efficient compaction in confined and varied job site conditions.
