Bomag Americas used the World of Asphalt show in Baltimore to put the spotlight on its new BW120SL-5 tandem vibratory roller. The machine, first launched at The Rental Show in February in New Orleans, features a vibration frequency 7-percent higher than previous models at 4,320 vibrations per minute.
Creating a 0.020-inch amplitude, the BW120SL-5 produces 8,993 pounds of centrifugal force on asphalt and base materials.
It can be operated in either manual mode or in Intelligent Vibration Control mode; the latter designed to provide precise compaction with the fewest passes required. In addition, vibration can be operated on either the rear or front drums independently, or in tandem.
The BW120SL-5 offers a Tier 4 final, 25 horsepower Kubota engine, and a maintenance-free articulation joint that provides up to 40 percent gradeability and 10-degree oscillation.
Other features include:
- Pressurized water spray system on both drums, with two filters and four spray nozzles
- Up to 2 inches of crab steering offset
- Vibration-isolated operator’s platform and suspended seat
- No daily grease points
- Wide-open, rugged hood for easy maintenance access
- Foldable ROPS
