Sakai has upgraded its SW654 series vibratory tandem rollers with a new Tier 4 Final, 3.3-liter Kubota diesel engine.
The machines, which the company says are designed for compaction on thin lifts, bridge decks, aging structures or over existing utilities, also include the new ECO Compaction Mode that reduces fuel consumption up to 37 percent.
“This upgrade raises the performance bar for all rollers just that much more, coupling the economics of maximum uptime with reduced cost of operation,” says Denver Weinstiger, vice president of sales and product support.
The series includes the single eccentric shaft SW654, the split drum SW654B and the twin-eccentric shaft SW654ND. They feature 42-inch-diameter, 58-inch-wide drums that reach 3,000 vpm in low frequency and 4,000 vpm in high frequency. Linear pressure ranges from 395 PLI on the SW654 to 715 PLI on the SW654ND.
