The BOMAG BW 120 SLC-5 combination roller features a steel vibratory drum at the front and four smooth rubber tires at the rear. The deep penetrating vibration of the drum force, combined with the kneading effect of the pneumatic tires, improve surface smoothness, says the company.
Powered by a 24.8-horsepower Kubota diesel engine that meets Tier 4-F emissions standards without a diesel particulate filter (DPF), the BW 120 SLC-5 has a 47.2-inch-wide front drum and delivers a 4,320-vpm vibration frequency and 0.020-inch amplitude. The roller’s center articulation joint provides plus-or-minus 10-degree oscillation to keep the drum and wheels in contact with material. The articulation joint is maintenance-free, and its bolt-on construction simplifies replacement when required.
Serviceability features include elimination of daily grease points, wide-opening hood for access to the engine compartment, and centralized electronics. Quick-disconnect spray nozzles for the front drum and tires, plus a central-tank water drain, facilitate water-system maintenance. The roller’s centralized lifting point speeds loading/unloading on a trailer, and its foldable ROPS reduces transport height.
