The BOMAG BW 190 AD-4 AM is a heavy-duty static smooth drum roller designed for high efficiency in soil and asphalt compaction. It features a single smooth steel drum with a diameter of 48.1 inches and a width of 78.8 inches, providing a static linear load of 170.8 pounds per inch for effective ground pressure. The drum operates with two vibration frequency settings at 46 and 57 vibrations per minute, and a nominal amplitude of 0.1 inches in medium mode, offering versatile compaction capabilities. Powered by a 134 hp (100 kW) Deutz TCD 2012 L04, 4-cylinder engine running at 2300 rpm, the machine balances strong power output with fuel efficiency, supported by a 52.9-gallon fuel tank and 2.6-gallon engine oil capacity. The BW 190 AD-4 AM has an operating weight of 26,896 pounds, optimal for achieving deep compaction and smooth finishes on asphalt or soil layers. Its dimensions include a ground clearance of 13.8 inches, an overall length of approximately 14.9 feet, a height of 9.9 feet to the top of the cab, and a wheelbase of 10.9 feet, allowing good maneuverability and operator visibility on construction sites. The 12-volt operating system powers essential functions. This unit provides reliable, high-quality compaction performance suitable for medium to large-scale road construction and maintenance projects where smooth surface finish and density are critical. Its robust build and adjustable vibratory settings ensure efficient compaction with minimal passes.
