BOMAG BW 211 D-3 STATIC SMOOTH DRUM ROLLER

Technical Description

The BOMAG BW 211 D-3 is a robust static smooth drum roller designed primarily for efficient compaction of sand, gravel, and water-bound base layers. It features a powerful 131.5 hp Deutz BF4M2012C four-cylinder diesel engine rated at 2300 rpm, delivering reliable performance in various earthwork applications. The machine operates at a maximum speed of 8.4 mph (13 kph) with a fuel capacity of 66.1 gallons, ensuring extended runtime on site. Its smooth steel drum has a diameter of 59.1 inches and a width of 83.9 inches, providing a substantial compaction surface. The BW 211 D-3 generates centrifugal forces of 53,055 lbs at high frequency and 38,218 lbs at low frequency, with vibration frequencies ranging from 1800 to 2160 vibrations per minute (vpm). The nominal amplitude is constant at 0.1 inches for both high and low settings. The static linear load measures 413.9 pounds per inch, optimizing soil density. Dimensionally, the roller measures approximately 18.5 feet in length, 7.4 feet in width, and 9.8 feet in height to the top of the cab, with a ground clearance of 19.3 inches and a wheelbase of 9.5 feet, ensuring stable and versatile handling. It operates on 12 volts electrical system and is equipped with 23.1/18-26 tires suited for construction terrain. The operating weight stands at approximately 22,928 lbs, balancing compaction power with maneuverability. The BW 211 D-3’s features and engineering make it suitable for a range of soil compaction tasks, with maintenance and operator comfort well integrated into its design.
