Technical Description
The BOMAG BW 138 AC is a light articulated tandem static smooth drum roller designed for asphalt compaction in road construction, repair work, and paving applications. It features a compact design with a 54.3 in (1,380 mm) drum width and a 57.5 in operating width, making it ideal for footpaths, small roads, and confined job sites. The machine is powered by a Deutz diesel engine, delivering reliable performance for continuous rolling and finishing tasks. With an operating weight of approximately 9,259 lb (4,150 kg) for the BW 138 AC-5 variant and a static linear load of 15.6 kg/cm, it provides effective compaction on thin asphalt layers while maintaining maneuverability. The roller has a tight inside turning radius of 142.2 in (3,612 mm), enhancing agility in tight spaces and around obstacles. Its articulated frame and tandem drum configuration ensure uniform compaction in a single pass, with both drums in constant contact with the surface for consistent results. Standard features include hydrostatic travel and vibration drive, a pressure sprinkler system with interval control, and two spring-loaded, tiltable scrapers per drum to prevent material build-up. The machine is equipped with a multi-function travel lever, multi-function display with operating hour meter, working lights, and a lockable engine hood for security and operator convenience. Designed for versatility, the BW 138 AC is suitable for soil and asphalt compaction, patching, and finishing work, offering a balance of power, precision, and ease of operation in a lightweight tandem roller package.
