SAKAI SW850 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW850 is a smooth drum vibratory roller designed for efficient asphalt compaction. It features a robust drum with a diameter of 55.2 inches providing centrifugal forces of 31,698 lbs (high) and 33,272 lbs (low) to ensure thorough compaction. The roller operates with high vibration frequency settings up to 4000 vpm, which accelerates compaction and produces a smooth, dense surface. Powered by the A-6BG1 engine delivering 120.7 hp at 2300 rpm, it balances performance with fuel efficiency supported by a 66.1-gallon capacity fuel tank. The SW850’s dimensions include an overall length of 19.1 feet, width of 7.3 feet, height to top of cab of 10.3 feet, and 13-inch ground clearance, facilitating maneuverability on various job sites. Its turning radius inside measures 169 inches with an 11.2-foot wheelbase. Operating weight is approximately 27,227 lbs, contributing to effective soil and asphalt densification. The design incorporates an articulated frame and operator station with excellent visibility, enhancing control and comfort. The machine’s water sprinkler system with corrosion-proof tanks keeps the drum wet for optimal performance in asphalt compaction. This model’s maximum speed is 6.9 mph, suitable for precise rolling control. The SW850 is widely recognized for its durability, ease of maintenance with accessible engine and hydraulic compartments, and high compaction force, making it highly suitable for road construction and paving projects requiring reliable smoothness and density.
