The 35° centerpoint articulated steering allows the front and rear tires to maintain tracking in turns.
The new BOMAG BW11RH-5 pneumatic tire roller features 35° centerpoint articulated steering, delivering a short 10-ft (3.0-m) inside turn radius. This allows the front and rear tires to maintain tracking in turns, offering full width compaction in tight, winding curves to reduce the number of passes to reach desired densities. The five front tires and four rear tires of the BW11RH-5 deliver a compaction width of 68 in (1,727 mm) with zero frame overhang, making this versatile roller the perfect machine for intermediate compaction of highways, urban development roads, parking lots, driveways and chip-and-seal applications, according to the company.
The machine’s five front tires deliver +/- 4° oscillation on the two outside tires and +/-5° oscillation at the three center to kneed and manipulate asphalt, improving mat density. The centerpoint steering joint offers +/- 10° oscillation to help maintain wheel contact with material at all times. The nine 7.5x15, 14-ply pneumatic tires offer standard fully ballasted wheel loads reaching 2,222 lb (1,006 kg) and ground contact pressure up to 82 PSI (5.7 bar).
Functional machine design of the new BW11RH-5 integrates ballast compartments into the frame. These strategically placed compartments lower machine center of gravity for excellent stability and safe operation. The BW11RH-5 offers a standard 12,231-lb (5,547-kg) operating weight, which can be increased to 20,000 lb (9,054 kg) by adding ballast to maximize compaction forces.
This new BOMAG pneumatic tire roller is powered by a liquid-cooled, 74-hp (55-kW) Kubota Tier 4 Final engine, meeting today’s most stringent emission standards. The roller’s hydrostatic transmission offers three travel speeds to match the speed of the paving train: 0-8 mph (0-12.9 kmph) in low range; 0-10.5 mph (0-16.9 kmph) in mid-range; and 0-15.5 mph (25.0 km/h) in high.
The BW11RH-5 comes standard with a 140-gal (532-l) tank. An optional pressurized spray system, complete with cocoa mats at each tire for even lubrication, is available to efficiently make use of available water and extend intervals between tank refills. When working in cooler ambient temperatures or windy conditions, optional heat shields help to maintain high tire operating temperatures, preventing asphalt pickup that could reduce mat surface quality.
A single, centrally located operator’s console on the BW11RH-5 features a swiveling seat to improve operator comfort and visibility, regardless of travel direction. A single lever provides effortless control of roller travel speed and direction. The operator’s console places controls within easy reach and provides unobstructed visibility, boosting operator productivity.
Designed with the service technician in mind, the BW11RH-5 features a wide-opening rear hood for easy access to the engine and all critical service points. All maintenance and check points are easily accessible from ground level, improving maintenance speed and safety. The maintenance-free, SAHR brakes are integrated into the travel motor, so the brakes apply automatically when the engine is shut down or with the loss of hydraulic system pressure in the transmission.
The new Tier 4 Final BOMAG BW11RH-5 pneumatic tire roller will be unveiled at World of Asphalt 2015, held at the Baltimore Convention Center, in Baltimore, Md., March 17-19. BOMAG Americas’ exhibit is located in booth #1130.
