BOMAG BW 161 AD-4 STATIC SMOOTH DRUM ROLLER

Technical Description

The BOMAG BW 161 AD-4 is a robust articulated tandem smooth drum roller designed for asphalt compaction and soil stabilization, ideal for road construction, parking lots, and light earthworks. It features a powerful 114 hp Kubota V3307 CR-T water-cooled diesel engine with emissions certification 3b/4, delivering high performance and fuel efficiency. The roller has an operating weight of approximately 21,164 lbs (gross weight 23,369 lbs), with a drum diameter of 48 inches and a drum width of about 6.1 feet. It exerts a centrifugal force of 20,233 lbs at high amplitude, combined with vibration frequencies ranging from 40 to 55 vibrations per minute, and a nominal amplitude of 0.1 inches, allowing effective compaction with dual amplitude and frequency settings. The machine is equipped with advanced braking systems, including a multi-disc parking brake and hydrostatic service brake, and employs an oscillatory articulation steering system for superior maneuverability. Its wheelbase measures 142.5 inches, with ground clearance of 9.8 inches and a maximum travel speed of 7.5 mph. The BW 161 AD-4 includes a large water spray tank capacity of 198.1 gallons to prevent asphalt from sticking to the drum during operation. Static linear loads are 170 pounds per inch at the front and 146.7 pounds per inch at the rear axle, which weigh 11,244 lbs and 9,921 lbs respectively. The unit operates on 12 volts and offers high operator comfort with easy service access, incorporating innovations such as BOMAP compaction documentation and the ECONOMIZER system for efficient and fuel-saving operation. This roller is engineered for durability, precision, and productivity in demanding compaction jobs.
