SAKAI SW652 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW652 static smooth drum roller is a high-performance compaction machine designed for efficient asphalt and soil compaction. It features a robust overall width of 4.8 ft (1.48 m) and dual smooth drums each 58 inches wide and 42 inches in diameter. The roller operates at a high vibration frequency ranging from 3,000 to 4,020 vibrations per minute (vpm), enabling rapid and uniform density achievement on hot mix asphalt (HMA) mats. Powered by a Kubota V3307-DI-T-KDN turbocharged, water-cooled, 4-cylinder diesel engine with a displacement of 3.331 liters, the engine delivers 55.4 kW (74.3 HP) at 2,600 rpm. This engine meets EPA Interim Tier 4 emission standards, balancing power with low emissions and fuel efficiency. The SW652-1 model weighs 7.35 metric tons (16,204 lbs) and exerts a substantial centrifugal force of 69 kN (15,510 lbf) for deep compaction. It reaches a travel speed of up to 13 km/h (8.1 mph), facilitating efficient site coverage. The roller includes advanced features such as a rugged articulated center-pin joint, patented rubber isolators that extend drum life, an anti-clogging sprinkler system with automatic shutoff in neutral, and a full operator view of drum surfaces for precise control. Safety features include an emergency brake pedal and high visibility standards. The vibration system employs a single eccentric shaft-driven hydraulic vibrator for reliability and performance. This machine is ideal for municipal and highway construction, parking lots, and sports courts where smooth, consistent compaction is essential.
