EquipmentWorld.com | September 2015 17 marketplace | by Amy Materson | AMaterson@randallreilly.com Hyundai Construction Equipment's lineup of new Series 9 rollers includes four single-drum models designed for soil and aggregate compaction, and two compact tandem-drum models for asphalt paving and maintenance. All six models deliver 360-de- gree operator visibility, up-to-date compaction technologies, quiet and fuel-effi cient engines and easily accessible maintenance points. The engine and other components are easily acces- sible through a wide opening engine hood that provides 270-degree front and side access. Soil compaction models The four Series 9 single-drum compaction roller models, the HR70C-9, HR110C-9, HR120C-9 and HR140C-9, have compaction drums available with a smooth or pad-foot surface and an optional pad-foot kit offers easy installation. The units feature a Perkins engine for the HR70C-9 and Deutz engines on the remain- ing models in the lineup. The models range in horsepower from 84 to 140, have operat- ing weights in the smooth-drum confi gura- tion ranging from 15,652 to 30,644 pounds, have drum widths from 67 to 83 inches and gradeability without vibration from 45 to 50 degrees. Hyundai's HA control delivers a continu- ous tractive effort at the axle and drum, allowing for automatic adapta- tion to various soil types and conditions. Dual frequencies and amplitudes provide two levels of vibration for effi cient surface and deep soil compaction. Paving compaction models The HR25T-9 and HR30T-9 tandem-drum roller models are specifi cally designed for aggregate paving applications; however, the machines also can be used for soil compaction. Both models have front and rear scrapers to prevent mate- rial build-up on the drums, and 55-gallon-ca- pacity water spray systems that sprinkle both the pavement surface and the drums, with sprinkling operator-adjustable intervals. The 5,400-pound HR25T-9 model has a drum width of 40 inches, and the 6,600-pound HR30T-9 model has a 50-inch drum width. Both models achieve maximum gradeability without vibration of 35 degrees, and are powered by a 30.2-horsepower Deutz D 2011 L2 I diesel engine.
