Efficiency

* Three frequencies (2,500vpm 3,000vpm and 4,000vpm) with dual amplitude vibration settings make the SW800 and SW850 very versatile rollers, applicable to asphalt pavement as well as base course.
* The 4,000vpm high frequency setting is especially effective for Superpave compaction. With this high frequency mode, the compaction work is sped up and a smoother surface is achieved due to closer impact spaces.
* Large diameter drums keep the pavement surface smooth and avoid hairline cracks.
* The directions of vibrator's rotation are arranged so that all effective compaction force is applied to the ground and uncomfortable vibration does not reach the operator station.
* Drive motors and vibration motors are cross-mounted between front and rear drums. This design balances the SW800 and SW850 not only front and rear, but also right and left. This feature keeps the machines rolling straight even at very slow speeds.

Easy operation and operator comfort
* The 180 degree rotating MPOS (multi-position operator station) provides all around visibility as well as a view of drum edges regardless of the direction of travel. The rotation of the operator station is smooth and effortless. The instrument panel is always located in front of the operator so that the monitoring of gauges and instruments is very easy.
* Like SAKAI's other vibratory rollers, the SW800 and SW850 employ a patented,unique vibration isolation system that offers the best riding comfort and a longer service life for its rubber isolators.
