The Hyundai Series 9 compaction rollers product line includes two compact tandem-drum models designed primarily for asphalt paving and maintenance. Both models offer 360-degree visibility for the operator. While the Hyundai HR25T-9 and HR30T-9 tandem-drum roller models are primarily designed for aggregate paving applications, contractors also may use these compact machines for soil compaction.
Both models feature front and rear scrapers to keep the drums free of material build up. They also provide 55-gallon-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 lb. (2 450 kg) and drum width of 40 in. (1,016 mm). The HR30T-9 model has an operating weight of 6,600 lb. (2 994 kg) and drum width of 50 in. (1,270 mm). 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 (22.5 kW).
All Hyundai Series 9 compaction roller models are designed with serviceability in mind. Engines and other components are easily accessible, thanks to the wide opening engine hood that provides 270-degree, 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.
