Upgrades by Sakai America Inc. to its static three-wheel R2H-4 roller do more than just meet the current EPA Tier IV emissions standards. Sakai engineers used the opportunity to make a proven design even better.

The Sakai R2H is a static roller for use on thin lifts and other jobs whose specifications restrict use of vibration. Its ability to reach tough density targets with a smooth mat finish comes from its big 64-in. (162.5 cm) diameter drums that deliver 365 pounds per linear inch compaction force.

The Sakai R2H redesign not only raises its emissions compliance to the EPA's current standards but features improved airflow to the engine, increased performance, more efficient hydraulic systems and a new drum configuration that makes maintenance and upkeep even easier.

Denver Weinstiger, Sakai VP of sales and product support, said, “This static three-drum model is a favorite design because it permits the use of great compaction force without shoving or pulling the material. That means you achieve a consistently dense mat in fewer passes. Fewer passes results in faster completion. Plus, the smooth mat the R2H-4 leaves requires less finish work after reaching your compaction target.”

The upgrade retains innovations such as Sakai's super-heavy-duty articulating and oscillating center hitch design for superior chassis stability, ground contact and operator control; neutral-activated dynamic hydrostatic braking, one of three separate braking systems found only on Sakai products for maximum operational safety, according to the manufacturer.
