BOMAG BW 278 AD-4 STATIC SMOOTH DRUM ROLLER

Technical Description

The BOMAG BW 278 AD-4 is a high-performance static smooth drum roller engineered for efficient soil compaction in road construction and earthworks. It features a 48-inch diameter smooth drum with a static linear load of 162.4 pounds per inch, providing uniform compaction. The dual vibration frequencies of 57 and 67 VPM with a nominal amplitude of 0.1 inches optimize compaction depth and effectiveness. Powered by a Cummins QSB4.5 4-cylinder diesel engine delivering 130 hp at 2200 rpm, the roller offers robust performance with a maximum speed of 10.1 mph. The machine weighs 25,800 lbs and has an operating width of 84.5 inches, allowing for efficient coverage and maneuverability with a 198-inch inside turning radius and 10-inch wheelbase. Key dimensions include 15 inches of ground clearance and an overall height of 9.3 feet to the top of the cab. The cooling system fluid capacity is 4.8 gallons and the engine oil capacity is 4.3 gallons, supporting durable operation. With a 60-gallon fuel tank and 12-volt electrical system, the BW 278 AD-4 is suitable for extended job site use. Its structure offers stability and comfort for the operator, making it ideal for compacting granular and mixed soils to achieve stable, dense subgrades and bases essential for road and infrastructure projects. This model balances power, precision, and efficiency to meet demanding compaction specifications in diverse terrain conditions.
