Sakai SW502S-1

Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam.


  • Sakai's new Eco compaction mode (ECM), which reduces fuel consumption up to 20%
  • High-low amplitude selector switch on the SW502S-1 and TW504 allows for use in wider applications.
  • Excellent gradability.
  • Vibration frequency 4,000 vpm allows high-speed compaction with optimum impact spacing (SW/TW354).
  • Built in safety features prevent accidental starting, starts only when the Forward, Neutral & Reverse lever is in the neutral position and press down the parking brake switch.
  • Emergency brake pedal is standard.
  • 1m x 1m visibility.
  • Sprinkler system with anti-clog package, i.e., a plastic water tank, triple-protection filtration, etc., and with perfect draining winterization.
  • Oil bath lubrication for drum vibrator mechanism.
