SAKAI R2H-2 STATIC SMOOTH DRUM ROLLER

Technical Description

The SAKAI R2H-2 static smooth drum roller is a robust asphalt compaction machine designed for uniform and efficient compaction without vibration (0 vpm). It features a 22-inch wide drum that delivers equal static linear pressure across all drums, ensuring a smooth finish and minimized distortion of hot mix asphalt mats. The machine has an operating width of 7.3 inches and a total rolling width of 83 inches. Powered by a Kubota V3307-DI diesel engine, a 3.3-liter, water-cooled, 4-cylinder, four-stroke diesel engine with direct injection and turbocharging, it produces 74 horsepower at 2200 rpm, meeting EPA emissions standards. The roller's operating weight is approximately 30,095 lbs, with a maximum operating weight near 30,930 lbs, distributed with 14,705 lbs on the front and 15,390 lbs on the rear. Its dimensions include an overall length of 198 inches, width of 83 inches, a height of 120 inches, and a wheelbase of 134 inches. Steering is articulated center-point, allowing excellent maneuverability. The all-drum hydrostatic drive ensures consistent power delivery and a smooth finish, ideal for applications where vibratory rollers are unsuitable, such as bridge overlays and roads with underground structures. The machine includes high safety standards with an emergency brake pedal and easy maintenance features like ground-level access to engine and hydraulic components and direct access to spray nozzles. This combination of powerful engine performance, precise compaction, and operator-friendly features makes the SAKAI R2H-2 suitable for various asphalt and soil base compaction tasks requiring static rolling.
