Description

Key specifications
  • Operating weight: 22,000 kg
  • Rated power: 140 kW (188 hp / 190 ps) @ 2,200 rpm
  • Vibration frequency: 28/32 Hz
  • Drum diameter: 1600 mm
  • Centrifugal force: 410/345 kN


Description
  • Flexible non‑impact excitation system extends vibratory bearing life beyond 10,000 hours, reducing component wear and maintenance downtime.
  • Dual‑frequency and dual‑amplitude vibratory modes provide adjustable compaction force for variable materials and layer thicknesses.
  • The larger 1600 mm diameter drum with consistent amplitude distribution ensures uniform compaction and fewer passes to reach target density.
  • ECO fuel‑saving mode with dual engine output reduces overall fuel consumption by over 12%; inverted engine layout and accessible service points simplify maintenance.
