SAKAI SW330-1 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW330-1 is a static smooth drum roller designed for efficient asphalt compaction and surface finishing. It features a 51-inch wide steel drum with a diameter of 27.6 inches, providing a high centrifugal force for effective compaction. Powered by a Kubota D1703-M-ET01 diesel engine delivering 35 hp at 2800 rpm, this unit offers reliable and robust performance. The engine is a 1.7-liter, 3-cylinder, water-cooled, 4-cycle vertical diesel with E-TVCS indirect injection for enhanced power, fuel efficiency, and low noise. The roller operates at a vibration frequency of 66.7 Hz (4,000 vibrations per minute), enabling optimum impact spacing for high compaction efficiency without sacrificing operational speed. Key dimensions include an overall length of 104 inches, width of 56 inches, height of 69 inches, and a 77-inch wheelbase. Its operating weight is approximately 6,550 lbs, with near-equal loads distributed on the front (3,175 lbs) and rear (3,375 lbs) drums to ensure balanced ground contact. The roller has a tight turning radius of 8.3 inches inside, facilitating maneuverability in confined spaces. Fuel capacity of 13.3 gallons supports extended operation, and the machine’s maximum speed is 7.5 mph. Additional features include hydrostatic transmission, articulated steering, and an ergonomic operator station designed for safety and ease of maintenance with removable water spray nozzles and multifunction braking systems. This combination makes the Sakai SW330-1 suitable for a broad range of compacting tasks, especially in road construction and asphalt paving applications requiring smooth, uniform surfaces.
