The BOMAG BW 151 AD-4 HF is a robust static smooth drum roller designed for efficient soil and asphalt compaction. It features a 66.2-inch wide steel drum with a diameter of 48.1 inches, providing a static linear load of 134.4 pounds per inch and a nominal amplitude of 0.1 inches at medium vibration. The drum vibrates at two frequencies, 40 and 60 vpm, optimizing compaction performance for various materials. Powered by a BF4M 2011 four-cylinder diesel engine delivering 80.5 hp at 2500 rpm, it offers reliable power for demanding compaction tasks. The roller’s operating weight is approximately 17,798 lbs, balancing compaction force and maneuverability. Key dimensions include a ground clearance of 15.8 inches, height to the top of the cab at 9.9 feet, overall length at 14.9 feet, and a wheelbase of 10.9 feet. The fuel tank capacity is 42.3 gallons, supporting extended operation with a maximum speed of 6.6 mph. Operating on a 12-volt system, the BW 151 AD-4 HF is engineered for versatility in road construction, site preparation, and earthworks, delivering uniform compaction with its static smooth drum configuration and dual vibration settings. Its design ensures operator comfort, durability, and efficiency for medium-scale compaction projects.
