BOMAG BW 278 STATIC SMOOTH DRUM ROLLER

Technical Description

The BOMAG BW 278 static smooth drum roller is a high-performance tandem roller designed for efficient asphalt compaction in road construction. It features a 78-inch-wide drum with a 48-inch diameter, delivering a static linear load of 967.2 lb/in for consistent mat density. The roller offers dual vibration amplitudes with a high nominal amplitude of 0.1 in and selectable vibration frequencies of 3,400 vpm (57 Hz) and 3,800 vpm (63 Hz), providing centrifugal forces of 30,349.3 lbs (high) and 37,071 lbs (low) to match varying mix and lift requirements. Powered by a Cummins 4B3.9 QSB-C130 engine, it produces 130.1 hp (97 kW) for reliable performance and smooth operation. The machine has an operating weight of 21,750 lbs and an operating width of 92.5 in, with a low-profile design that enhances operator visibility. Standard features include a pressurized water spray system, joystick controls, and a sliding/pivoting seat for improved ergonomics and control. With a maximum speed of 10.1 mph (16 km/h), a 60-gallon fuel tank, and generous service capacities, the BW 278 is built for long shifts and demanding paving applications, ensuring high productivity, excellent smoothness, and uniform density on asphalt surfaces.
