Hamm’s “earthshaking” full line of technically advanced, Tier IV-interim emissions compliant H i-series of soil compactors is making waves in North America.

Since its introduction, the 43,383-lb. (19,678 kg), 84-in. (213 cm) wide H 20i has earned its place as a leader in the dirt roller market, and led the way for its six-cylinder brother machines, the 41,310-lb. (18,738 kg), H 18i, and the 54,077-lb. (24,529 kg) H 25i.

Now, the four-cylinder, 24,617-lb. (11,166 kg) H 11ix, 28,034-lb. (12,716 kg) H13ix, 25,434-lb. (11,536 kg) H 11i, 28,863-lb. (13,092 kg) H 13i, and 35,610-lb. (16,152 kg) H 16i soil compactors are available for North America. In addition to the standard smooth drum models, all H-series compactors are available in padfoot (“P”) configurations, and the H 13i VIO combines conventional vibration with Hamm Oscillation compaction in a single drum.

“The big six-cylinder, Tier IVi machines — the H 18i, H 20i and H 25i — were introduced in 2012,” said Richard Evans, vice president of sales of Hamm. “Now the full line of four-cylinder H11ix, H13ix, H 11i, H 13i and H 16i is available.”

Hamm’s H-series now incorporates Hammtronic drive control system on all models.

“Hammtronics now is standard on all H-series machines, and it eliminates the manual traction control button, with ASC [automatic slip control] integrated within the Hammtronic drive,” Evans said. “Gradeability is enhanced with no manual input, so the machines are simpler to operate. As with the HD+ series, Hammtronics offers power-on-demand for enhanced fuel economy and less wear on components, and programmable speed control for more consistent compaction.”

The six- and four-cylinder engines in the Hi series are more powerful than in previous models, while delivering Tier IV-interim emissions control.

“When you combine the additional power with the standard Hammtronics system you have a very useful machine of great benefit to the customer,” Evans said.

The new models come with an innovative air filter, which is extremely simple to clean and replace. They also provide as standard a secure storage space below the engine cover in which to keep a toolbox for example.

The new H11ix and H13ix models develop 114 hp and do not require a diesel particulate filter (DPF). The new H 11i, H 13i and H 16i rollers develop 141 hp while combining modern combustion technology, exhaust gas aftertreatment and a DPF with automatic regeneration to reduce emissions. Their three-point swivel joint makes them maneuverable with optimum directional stability. Due to their large front and rear angles of slope, they are able to work well in the most difficult terrain, according to the manufacturer.
