The BOMAG BW 161 AD static smooth drum roller is engineered for efficient asphalt and soil compaction, featuring dual 4.1 ft diameter drums with a width of 66.2 in, providing a robust 13,938 lbs centrifugal force in high mode to ensure thorough compaction. It is powered by a naturally aspirated 4-cylinder Deutz BF4L 913 engine delivering 102 hp gross and 93.9 hp net at 2150 rpm, balancing power with fuel efficiency. This machine has an operating weight of approximately 21,460 lbs and a maximum speed of 8.1 mph, facilitating effective work cycle times on site. Its compact dimensions include a 6.2 ft width, 15.8 in ground clearance, and 9.6 ft height to the top of the cab, allowing versatility in various environments. The vibration system produces nominal amplitudes of 0.1 in at frequencies of 30 and 45 vpm, optimizing compaction quality while minimizing surface damage. The hydraulic and fuel capacities are 219.3 and 34.1 gallons respectively, supporting extended operation. Equipped with a 12-volt system, this roller emphasizes reliability and ease of maintenance. Its design prioritizes operator comfort and control, meeting productivity demands in road construction and maintenance applications. Overall, the BW 161 AD combines powerful compaction forces, efficient engine output, and practical dimensions to deliver high-performance smooth drum rolling for asphalt and soil compaction tasks.
