Sakai has launches its SW654 Series vibratory double-drum compactors that have a Kubota 73-horsepower engine that meets Tier 4-Final standards. Eco Compaction Mode (ECM) reduces fuel consumption up to 37 percent.
Vibratory compaction by the 58-inch-wide, 42-inch-diameter drums is achieved at 3,000 vpm in low frequency or 4,000 vpm in high frequency. High-frequency rear drum dynamic linear pressure ranges from the SW654 roller’s 395 pli to the SW654ND roller’s 715 pli.
The SW654 has a single eccentric shaft and a split drum. The SW654B and SW654ND have twin-eccentric shafts.
Tandem vibratory rollers compact freshly placed asphalt mats to specific densities using two, smooth steel drums that vibrate to consolidate the material. Many have sophisticated systems that continually measure density as compaction progresses and adjust compaction effort to avoid over-compaction. Using GPS and proprietary software, some rollers can capture a digital record of compaction results
