Three frequencies (2,500vpm, 3,000vpm and 4,000vpm) with dual amplitude vibration settings make the SW800, SW850 and SW900
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 si 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, SW800N,
SW850 and SW900 not only front and rear, but also right and left. This feature keeps the machines rolling straight evenat very slow
