The BOMAG BW 11 AS is a static smooth drum roller designed for efficient compaction in construction and roadwork applications. It features a front drum diameter of 4.1 ft and a rear drum diameter of 5.1 ft, both with a drum width of 54 inches, providing a compaction width of 62.5 inches. The machine has a standard operating weight of 17,320 lbs, which can be increased with ballast to a maximum of 24,250 lbs to enhance compaction force. Powered by a Cummins 4B3.3TAA engine delivering 78 hp at 2100 rpm, it offers robust performance with a maximum speed of 10.2 mph (16 kph). The roller has a ground clearance of 1.7 ft, an overall width of 5.3 ft, a height of 6.5 ft (9.2 ft including ROPS/FOPS), and a wheelbase of 11.7 ft, ensuring good maneuverability and stability on site. It operates on a 12-volt electrical system and includes a cooling system fluid capacity of 4 gallons, hydraulic system fluid capacity of 15.1 gallons, and a fuel tank capacity of 30.2 gallons. The roller also features a spray water system with a 170.4-gallon capacity to prevent material adhesion to the drum during operation. The maximum static linear loads are 251 pounds per inch for the drive drum and 198 pounds per inch for the guide drum, making it suitable for compacting granular and mixed soils effectively. This model is well-suited for medium-scale compaction tasks where static rolling is preferred over vibratory compaction.
