The BOMAG BW120SL-5 tandem vibratory roller has a 4,320 vpm (72 Hz) vibration frequency to quickly complete asphalt compaction projects. The roller’s drive motors and maintenance-free articulation joint deliver up to 40% gradeability and +/-10-degree oscillation for reliable performance when compacting soil and base material, according to the company. Combined, these features help the BW120SL-5 complete new development construction, road repair, road construction finishing, and landscaping projects.
Offering 0.020-in (0.50-mm) amplitude, the BW120SL-5 roller generates 8,993-lb (40-kN) centrifugal force to deeply penetrate asphalt and base materials. Operators can select either manual vibration or Intelligent Vibration Control (IVC), designed to deliver optimum compaction results with minimal passes. Vibration can be imparted to both drums, front drum only, or rear drum only to tailor vibration needs to jobsite conditions.
The roller’s rugged bolt-on center articulation joint includes a maintenance-free design with no grease points for a reliable, low-cost operation. Its 25-hp Kubota diesel engine meets Tier 4 final emissions standards without requiring a diesel particulate filte, eliminating the need for filter regeneration. The operator’s console features an ergonomic, easy-to-understand control layout.
The BW120SL-5 has a pressurized water spray system for both drums. Two filters on the water system help keep water particles from entering the pressurized system, and the four spray nozzles feature a quick-disconnect design for fast and easy unplugging. The operator selects from five different timing intervals for water spray, extending operating intervals between refilling the 43.6-gallon water tank. The spray nozzles are shielded to ensure uniform drum coverage with water, even when operating in windy conditions. Two spring-loaded scrapers per drum clear the drum of debris in either travel direction and are tiltable for easy cleaning.
