High-frequency Compactors

The DD-118HF and DD-138HF high-frequency compactors offer eight amplitude settings that enable you to achieve the required density without fracturing aggregate particles in the mix.

• Vibration frequencies of 3,400 and 3,200 vpm with centrifugal force of 42, 680 and 42,260 lbs.
• SMART start system for consistent mat quality and density
• Impact meter enables operator to precisely control optimal rolling speed for the desired drum impact spacing
• Dual water spray drum wetting system
• Four- and six-cylinder Cummins engines
• Hydrostatic direct drive to both drums
