Offering high 4,320 vpm (72 Hz) vibration frequency, the BOMAG BW120SL-5 tandem vibratory roller features Intelligent Vibration Control (IVC) to increase compaction efficiency. With IVC, the exciter system guarantees consistent compaction of the material with reliable results achieved in minimal passes. Adding the optional BOMAG Economizer to the roller removes the guesswork out of compaction and eliminates over-compaction by measuring and displaying material stiffness via a simple-to-read LED light gauge on the dash.
The BW120SL-5 roller generates 8,993-pound (40-kN) centrifugal force to deeply penetrate asphalt and base materials. The flexible machine allows the operator to choose between vibration for both drums, front drum only or rear drum only to tailor vibration needs to jobsite conditions. The roller’s powerful drum drive motors deliver up to 40 percent gradeability for reliable performance when compacting soil and base material. Combined, these features make the rental-friendly BW120SL-5 the perfect all-around tandem vibratory roller for quickly completing new development construction, road repair, road construction finishing and landscaping projects.
The roller’s durable centre articulation joint delivers +/- 10-degree oscillation to keep the drum in contact with the material on irregular surfaces. Its bolt-on construction offers easy removal and a maintenance-free design with no grease points delivers reliable, low-cost operation, making it the right roller for rental yards. The centre joint provides up to 2 inches (50 mm) of offset crab steering to increase visibility to the front drum and simplify compacting along edges and road finish work.
The BW120SL-5 roller’s overall low-maintenance design increases uptime and production in the field. No grease-daily points reduce daily maintenance time and costs, while a wide-opening hood offers unimpeded access to the engine and central electronics panel. Easy accessibility to the water pump, spray nozzles and central tank water drain allows service personnel to quickly maintain the water system. A centralized lifting point enables the roller to be quickly loaded and unloaded on a trailer, while a foldable ROPS structure reduces machine transport height.
The BOMAG BW120SL-5 roller’s pressurized water spray system and large 43.6-gallon (165-L) water tank provide long operating times between refills. The operator can select from five different water spray timing intervals to further extend operating intervals between refilling. The spray nozzles are shielded to ensure uniform drum coverage, especially when operating in windy conditions. Two filters on the water system help keep particles from entering the pressurized system, and the spray nozzles feature a quick-disconnect design for fast and easy unplugging. Front and rear spring-loaded scrapers clear each drum of debris in either travel direction and can be tilted for easy cleaning.
The BW120SL-5 tandem vibrator roller is powered by a 25-hp (18.5-kW) Kubota diesel engine that meets Tier 4 Final emissions standards without requiring a diesel particulate filter (DPF), eliminating the need for and extra expense associated with filter regeneration. The operator’s console features an ergonomic, easy-to-understand control layout for intuitive machine control for varying levels of operator experience.
