Hamm unveiled its new line of HD+ i-series tandem asphalt compactors at Conexpo. “The big change here is that we are now using Tier 4 Interim engines,” said Richard Evans, vice president of sales for Hamm.
On display at Conexpo were the 6.4tonne Hamm HD+ 70i VT, combining smooth drum with pneumatic tyres; the 10.4tonne HD+ 110i VO oscillation roller, combining standard vibration with Hamm oscillation compaction; the 12tonne HD+ 120i VV HF, a high-frequency roller; and the 14tonne HD+ 140i VV, with stand

Hamm has also launched the HD+ 80i weighing 7.3tonnes, and the HD+ 90i weighing 9.1tonnes. Both models come with a variety of options, including conventional vibration, high frequency compaction, exclusive Hamm oscillation compaction, split drums, and a smooth drum/pneumatic combination option.
All the rollers are equipped with the Hammtronic machine management system, aimed to optimise performance while minimising fuel consumption, by operating the engine in the optimum load range at all times. The engines in the HD+ 70i and HD+ 80i are already Tier 4 Final compliant, so won’t require updating again.
"These machines have been developed specifically to meet the criteria of the North American contractor," said Evans.
The fully adjustable seat – with integral control levers – moves with the operator’s console from side to side and swivels through 180 degrees, aimed to give much better control and visibility, particularly to the drum edges.
"In addition, if you are a big guy, the steering column tilts up out of the way when you are climbing in or out of the seat," Evans said. "Also, the drive levers are wide, so you have plenty of room for your legs."
