Asphalt RollersBW 11 RH-5

MAINTENANCE: EASY!

• The hood opens fully without effort.
• No lubrication points.
• Fillers can be released simply under the access step. The vertical radiator requires no additional cleaning.

EFFECTIVE BY DESIGN!

• The well-thought-out design offers optimal driving characteristics with a low centre of gravity and even weight distribution.

FLEXIBILITY: TOTAL!

• Central articulated steering, hydrostatic drive with three speeds, functional frame design: perfect features for highly flexible use and manoeuvrability.

OPERATION: SUPER EFFICIENCY!

• Profitable work and great ergonomics: Cab with extra large glass windows, clearly arranged console, intuitive operation – the operator can relax and concentrate on the task at hand.

COST-EFFECTIVENESS: HIGH!

• High speeds up to 20 km/h mean large surface coverage.
• Ideal for surface chipping.

FASTER SERVICE AT LESS COST

• The engine hood opens effortlessly and fully. To make maintenance as easy as possible, the engine and all service points are readily accessible from the ground. After all, you have more important things to do.

SMART DESIGN DETAILS

• The maintenance-free articulated joint is not welded to the frame. Also, the smart frame design guarantees long service life.

COOL RADIATOR

• The radiator is in an excellent vertical position right behind the cab. This means it stays clean and doesn’t need extra cleaning. Maintenance-free SAHR brakes also increase the ease of service on this model.

FUNCTIONAL DESIGN

• The functional frame design of the BW 11 RH-5 provides the basis for this pneumatic tyred roller’s superior driving characteristics. A machine’s centre of gravity is well known to affect its stability. The lower it is, the more stable the unit. BOMAG engineers have strategically placed the ballast compartments to ensure a lower centre of gravity, providing a high level of stability and even distribution of weight. The BW 11 RH-5’s clever frame design offers the optimum conditions for perfect work results.

BALANCED WEIGHT RATIOS

• Precisely balanced weight distribution directly affects a range of roller characteristics. Handling, acceleration, traction and the service life of components also play a role. The result is perfect driving characteristics. And superior surface quality and compaction.

TUNED DRIVE

• The state-of-the-art hydrostatic drive of the BW 11 RH-5 is in a class of its own. Whether driving fast or slow, on steep inclines or for high surface coverage: three speeds allow the right choice for any application.

ALL GOOD THINGS COME IN THREES

• The three speeds mean the driver can choose the right performance for each application. The first gear guarantees the drive maximum drive gradeability – perfect for compacting gradients. The second gear can be used universally for the most varied of applications. But whenever high productivity is required, the third gear provides top speed. A typical example is chipping work.

HIGHLY RESPONSIVE MACHINE USE

• The BW 11 RH-5’s hydrostatic steering system is equipped with a steering wheel like in cars. The hydrostatic drive allows for highly responsive driving control, even on sharp bends, as well as easy manoeuvring thanks to the smooth reversing provided by the “soft reverse” feature.

ULTIMATE ACCURACY: CENTRAL ARTICULATED STEERING

• The centrally positioned articulated steering allows the wheels to keep the entire roller width on the ground when turning. The wide steering angle of 35 degrees enables the roller to navigate the tightest of bends. This means perfect compaction results in fewer passes.
• Complete ground contact: the articulated joint can also move an additional 10 degrees. This is how to achieve even compaction on uneven surfaces.

THE FIRST CHOICE

• Thanks to the high speeds possible, the BW 11 RH-5 is also the first choice when it comes to chipping. Chip sealing is currently the most cost-effective method of renewing a road surface. In terms of service life and effectiveness it is comparable to other methods, but costs significantly less – up to 25% of the cost of road surface course renewal.

ROAD REJUVENATION

• Chip sealing is applied on top of an existing surface to protect it from tyre damage and the sun, and to prevent water ingress. This extends the service life of roads. At the same time, the macro texture increases surface skid resistance. The roller can be used to compact base material, sand and asphalt.

WATER SPRAYING SYSTEM

• The tyres need moistening, but the water supply must be regulated. Once warm, very little water is needed.
• The BW 11 RH-5 offers a choice of 5 spraying levels. In addition, the scrapers can be folded away individually, which also increases work output.

THERMAL APRONS

• Thermal aprons ensure fast heating of the tyres while maintaining an even tyre temperature. This also prevents asphalt pick-up, which can damage surfaces.

BALLAST

• The BW 11 RH-5’s wide range of applications may require different machine weights. The ballast options available enable the model to handle a wide variety of work. Choose between a 7 t and 9 t version for chipping and asphalt applications, or the 11 t version for sand and base compaction (only available with ROPS).

TYRE INFLATION SYSTEM

• The success of a compaction job largely depends on selecting the correct contact pressure. An external compressor can be used to inflate the tyres from a central adjustment point. This ensures that the tyres contact the surface evenly, producing perfect results.

TEMPERATURE SENSOR

• The asphalt temperature sensor provides a constant overview of the asphalt temperature, indicating if the material is too hot or cold. The operator therefore keeps the roller in areas where the material has the correct rolling temperature, and avoids wasting time on material that is too cold.

ADDITIONAL LIGHTING

• Some jobs require night work, especially when deadlines are tight, or during the autumn and winter season. The optional side lights on the BW 11 RH-5 provide clear visibility, especially to the sides, during over-night operations.
