SAKAI CR271 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai CR271 is a vibratory tandem smooth drum roller designed for efficient compaction in asphalt and construction applications. It features a 35.5-inch wide drum with a diameter of 22 inches, delivering a vibration frequency of 4,000 vpm (66.7 Hz) and a centrifugal force of 2,975 lbs, which ensures optimal impact spacing and compaction efficiency. The roller's operating weight is approximately 3,265 lbs (1,480 kg), providing sufficient ground pressure for uniform surface finishing. It has a compact turning radius of 6.3 inches inside, enhancing maneuverability in confined spaces. Powered by a reliable Honda GX630R gasoline engine, this unit produces 20.8 horsepower at 3,600 rpm, driven by a 688 cc, air-cooled, 4-stroke V-twin OHV design known for quiet operation, fuel efficiency, and durability. The engine includes features such as a digital CDI ignition with variable timing, two-barrel inner-vent carburetor for precise fuel metering, a rev limiter, and an electric start system. The roller has a fuel capacity of 7.9 gallons and a water sprinkler system capacity of 40 gallons for drum wetting to prevent material adhesion during operation. Additional design highlights include chamfered drum edges, superior shock absorption, high curb clearance, and excellent operator visibility supported by steel hood and decking construction. The CR271 operates at speeds up to 4.7 mph (7.5 km/h) with a gradeability of 25%. Its compact size, powerful compaction capabilities, and dependable Honda engine make it suitable for diverse asphalt and soil compaction tasks in construction projects.
