Technical Description

The Sakai SW330-I is a compact smooth drum roller designed for efficient asphalt and soil compaction in small to medium-sized projects such as municipal streets, driveways, and parking lots. It features a 51-inch wide smooth drum with a drum diameter of 27.6 inches, delivering a vibration frequency of 66.7 Hz (4,000 vibrations per minute) and a centrifugal force of 7,055 pounds, ensuring high compaction efficiency and clean surface finishes. The roller is powered by a Kubota D1703-M-ET01 diesel engine, a 3-cylinder, vertical, water-cooled, 4-cycle engine with a displacement of 1.647 liters (100.6 cu in), producing 34.1 hp at 2800 rpm. The engine's indirect injection system and Kubota’s advanced combustion technology provide reliable, quiet, and fuel-efficient operation. The SW330-I measures approximately 4.7 feet in operating width, 8.7 feet in overall length, and 5.75 feet to the top of the cab, with an operating weight around 6,500 to 6,900 pounds. It has a tight turning radius of 8.3 inches inside, hydrostatic transmission, and safety features including excellent 360-degree visibility and an automobile-style emergency brake system. The fuel capacity is 13.3 gallons, and it achieves a maximum speed of 7.5 mph. Its design includes high curb clearance and articulated steering for maneuverability and smooth compacting performance on diverse job sites. The machine’s maintenance is user-friendly with tool-free water spray nozzle removal to aid in surface finishing during operation.
