Hyundai Construction Equipment Americas’ Series 9 compaction rollers product line includes four single-drum models designed primarily for soil and aggregate compaction and two compact tandem-drum models designed primarily for asphalt paving and maintenance. All six models offer 360-degree visibility for the operator.
The four Hyundai Series 9 single drum compaction roller models feature fuel-efficient and reliable engines including a Perkins engine for the HR70C-9, and Deutz engines on models HR110C-9, HR120C-9, and HR140C-9.
The single-drum models are designed primarily for soil compaction applications. The compaction drum is available as a smooth or pad-foot surface. The optional pad-foot kit is designed for easy installation.
Hyundai’s HA control delivers a continuous tractive effort at the axle and drum for automatic adaptation to various soil types and conditions. Dual frequencies and amplitudes provide two levels of vibration for both surface and deep soil compaction.
The Hyundai Series 9 single-drum roller models range in horsepower from 84 to 140 hp, in operating weight for smooth-drum configuration from 15,652 to 30,644 lbs., in drum width from 67 to 83 in., and in gradeability without vibration from 45 to 50 degrees.
While the Hyundai HR25T-9 and HR30T-9 tandem-drum roller models are primarily designed for aggregate paving applications, they may also be used soil compaction. Both models feature front and rear scrapers to keep the drums free of material build up. They also provide 55-gal.-capacity water-spray systems that can sprinkle both the pavement surface and the drums, with operator-adjustable sprinkling intervals. Each model offers the largest drum in its weight class for optimum compaction results.
Other standard equipment on both Hyundai tandem-drum roller models includes ROPS roll bar, hydrostatic drive, hydrostatic vibration system at both drums, automatic vibration mode (double/single vibration), spring-loaded brakes on both drums, manual emergency stop switch with touch sensitive switch at the seat, spring-mounted driver's compartment, four headlights, driver's seat with arm rests and safety belt, and lockable dashboard.
The HR25T-9 model has an operating weight of 5,400 lbs. and drum width of 40 in. The HR30T-9 model has an operating weight of 6,600 lbs. and drum width of 50 in. Both models achieve maximum gradeability without vibration of 35 degrees, and are powered by a Deutz D 2011 L2 I diesel engine rated at 30.2 hp.
