Six Models Included in Hyundai Series 9 Compaction Roller Line

The Series 9 compaction roller line includes four single-drum models (HR70C-9, HR110C-9, HR120C-9 and HR140C-9) designed primarily for soil and aggregate compaction and two compact tandem-drum models (HR25T-9 and HR30T-9) designed primarily for asphalt paving and maintenance. All six models offer 360° visibility for the operator.

Engines and other components are easily accessible, thanks to the wide opening engine hood that provides 270° front and side access. The low-maintenance articulated joint features Teflon wear shells on all bearings to eliminate the need for frequent greasing. The vibration systems are designed for long life and reduced maintenance requirements.
