SAKAI R2H-1 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai R2H-1 Static Smooth Drum Roller is engineered for high-quality asphalt and granular base compaction with uniform static pressure across its large front and rear drums, each measuring approximately 5.4 feet in diameter. Powered by a Hino W04D-F diesel engine delivering 75.1 hp at 2050 rpm from a 244.7 cu in displacement, this roller achieves a maximum speed of 10 mph with efficient hydrostatic all-wheel drive. Its operating width is 83 inches, ideal for smooth, consistent compaction over wide surfaces. The roller features a robust overall construction, with an operating weight of up to 30,930 lbs (max ballast) ensuring high linear static loads of 882 pounds/inch on the drive drum and 932 pounds/inch on the guide drum, promoting superior density without vibration. The machine measures 16.5 feet in length, 6.9 feet in width, and 8.6 feet in height, extending to 10.1 feet with ROPS/FOPS for operator safety. A tight turning radius of 165 inches and an 11.2-foot wheelbase provide maneuverability on confined job sites. Ground clearance is 1.2 feet, balancing stability and accessibility on uneven terrain. The roller’s articulated design and static operation preserve asphalt integrity while delivering a smooth finish free of mats pushing or shoving. It is suited for municipal paving, bridge decks, and applications requiring vibration-free compaction, providing efficient, durable, and precise performance for consistent results in diverse paving environments. Maintenance access is simplified for engine and hydraulic systems, supporting reliable uptime on site.
