Technical Description
The Sakai SW320-1 is a robust smooth drum roller designed for efficient soil and asphalt compaction. It features a 47-inch wide steel drum with a diameter of 27.6 inches, delivering a vibration frequency of approximately 66.7 Hz (4,000 vpm) and a centrifugal force of 7,059 lbs, ensuring high compaction efficiency. Powered by a Kubota D1703 diesel engine, this model produces 34.1 horsepower at 2,800 rpm, with a displacement of 100.6 cubic inches, providing reliable and consistent power output. The engine is water-cooled, 3-cylinder, and offers excellent durability and noise reduction through Kubota's advanced design technologies.
The roller’s operating weight is roughly 6,327 lbs, balancing load distribution with about 3,085 lbs on the front axle and 2,865 lbs on the rear axle. It achieves a maximum speed of 7.5 mph, with a compact turning radius inside of 8.6 inches for enhanced maneuverability. Dimensions include an overall width of 4.37 feet, length of 8.7 feet, height of 5.75 feet, wheelbase of 6.4 feet, and ground clearance of 9.85 inches, ideal for diverse job site conditions. The machine incorporates dual hydrostatic drum drives, independent vibration control for each drum, and a non-corrosive water spray system to maintain drum cleanliness during compaction. Safety and operator comfort are addressed with an open ROPS and seatbelt system, vibration controls at the instrument panel, and excellent drum edge visibility. This combination of features makes the Sakai SW320-1 a versatile and efficient compactor suitable for a variety of construction applications.
