Hyundai Construction Equipment Americas recently announced enhancements and an addition to its compaction-roller product line. A new tandem-drum model, the HR26T-9, joins two previously available models, and Hyundai's four single-drum rollers — the HR70C, HR110C, HR120C and HR140C — now feature Tier IV Final-compliant engines.
Hyundai's compact, tandem-drum roller models are designed for asphalt paving and maintenance, while the single-drum roller models are well suited for soil and aggregate compaction. All Hyundai compaction roller models offer 360-degree visibility for the operator.
“The Hyundai compaction roller product line combines the most up-to-date compaction technologies with quiet, fuel-efficient engines, a safe and convenient operator environment and easily accessible maintenance points for outstanding overall performance and value,” said Juston Thompson, product specialist, Hyundai Construction Equipment Americas. “This product lineup gives solid options to users across the compaction market's highest-volume segments.”
Compact Tandem-Drum Models Designed for Paving
The new Hyundai HR26T-9 model has an operating weight of 6,400 lb. (2,900 kg) and drum width of 47 in. (120 cm), with a working width of 49 in. (125 cm). A Tier IV Interim-compliant Deutz D 2011 L2i diesel engine rated at 31 hp (23 kW) powers the HR26T-9.
While the Hyundai tandem-drum roller models are primarily designed for asphalt paving applications, contractors also may use these compact machines for soil compaction. The tandem-drum rollers feature front and rear scrapers to keep the drums free of material buildup. They also provide 55-gal. (208.2 L) water-spray systems that can sprinkle both the pavement surface of 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 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 armrests and safety belt, and lockable dashboard.
Single-Drum Models for Soil Compaction
Hyundai single-drum roller models now meet Tier IV Final emissions regulations with Deutz and Cummins engines that range in horsepower from 73 to 132 (54 to 97 kW). The HR70C model features a Deutz TD2.9 L4 engine. The HR110C, HR120C and HR140C models all feature a Cummins QSF 3.8 engine.
The four single-drum models are designed primarily for soil compaction applications. The compaction drum is available as a smooth or pad-foot surface. A pad-foot kit is available for use with the smooth drum. Continuous tractive force adjustment automatically assures maximum traction. Two-stage vibration provides both surface and deep compaction.
In the smooth-drum configuration, Hyundai's single-drum roller models have operating weights ranging from 15,650 to 30,865 lb. (7,100 to 14,000 kg). Drum widths range from 67 to 83 in. (170 to 210 cm). Gradeability without vibration ranges from 45 to 50 degrees.
Industry Leading Warranties
Hyundai compaction rollers are protected by Hyundai's three-year, 3,000-hour full-machine standard warranty. Hyundai compaction rollers also have lifetime warranties on articulation joints. An optional program, Hyundai Extend, offers a customized extended warranty with the industry's longest term coverage.
