The SW652ND double-drum compactor from Sakai oscillates or vibrates on both drums simultaneously.
The SW652ND double-drum roller from Sakai America oscillates or vibrates on both drums simultaneously. Each drum is controlled independently, which enables the roller to to achieve the required compaction faster on thin and thick lift asphalt applications, according to the company. The model's vibration mode is typical of other Sakai compactors, offering a high frequency of 4,020 vpm. The more gentle oscillation mode offers a new drum motion designed to neither over-compact the mat nor fracture the aggregate, which is especially useful when compacting thin lifts and in gaining density at the joints and during finish passes. Estimated list price: $115,000 to $135,000.
Sakai America’s 300 Series rollers include three double-drum steel and two steel/pneumatic-tire combinations, all with high frequencies of 4,000 vibrations per minute.
Sakai’s high impact, low vibration rammers – the RS45 at 110 pounds, RS65 at 160 pounds and RS75 at 180 pounds – are powered by Honda gasoline engines ranging in horsepower from 2.3 to 2.8.
