The globally popular and powerful “tandem rollers with a plus” series has been growing: at Conexpo 2014, Hamm is displaying for the first time in the US new models of the articulated HD+ rollers with operating weights of 7 t ( 14,000 lbs.) and 8 t (16,000 lbs.).

Hamm has again expanded the range of HD+ series rollers by nine machine types with service weights of 7 t (14,000 lbs) and 8 t (16,000 lbs). The new HD+ 70i (7 t / 15,000 lbs.), roller drum width (1.50 m / 5 ft) and HD+ 80i (8 t/ 16,000 lbs.), roller drum width (1.68 m / 5.5 ft) are available as vibratory, oscillatory, combi and high frequency rollers. The HD+ 80i will also be offered with a split drum.

Equipped with state-of-the-art engine technology, the HD+ 70i and HD+ 80i rollers comply with the very stringent Tier 4f exhaust gas regulations in force since 2014. The Deutz 55.4 kW 4-cylinder diesel engine is fitted with a diesel oxidation catalyser (DOC) to reduce particulate emissions.

The larger rollers HD+ 90i and HD+ 110i (85 kW) as well as HD+ 120i and HD+ 140i (115 kW) are available with new Tier 4i-compliant engines now.

Since its launch in 2010, the HD+ series has received multiple awards for its successful design and usability, amongst them the iF design award 2010 in gold, the red dot design award 2010, the American “Good Design Award” and the French “Observeur du design”. This makes it the most highly accoladed construction machine in the world.
