BOMAG BW 138 AD-4 STATIC SMOOTH DRUM ROLLER

Technical Description

The BOMAG BW 138 AD-4 is a compact static smooth drum roller engineered for efficient asphalt and soil compaction in road construction and landscaping. It features a Kubota engine, delivering reliable power for consistent operation. The roller has a drum width of 54.4 inches and a drum diameter of 31.9 inches, providing a substantial contact area for effective compaction. With vibration frequencies ranging from 2,820 to 3,480 vibrations per minute (vpm), it ensures optimal surface smoothness and compaction density. The machine’s operating weight is approximately 9,235 lb, balancing maneuverability and compaction force. Its turning radius inside is 103 inches, allowing precise handling in confined spaces. Dimensions include an overall length of 8.54 ft, height to the top of the cab of 8.88 ft, wheelbase of 5.88 ft, and ground clearance of 12.8 inches. The roller achieves a maximum speed of 6.3 mph and operates on a 12V electrical system with a fuel capacity of 14.6 gallons. The static linear load is 86.3 lb/in, complemented by a nominal medium amplitude of 0.1 inches and a centrifugal force at medium amplitude of 9,666.8 lb. Designed with durability in mind, the BW 138 AD-4 offers robust construction, ease of maintenance, and effective vibration control for uniform compaction, making it suitable for small to medium-sized paving and repair projects.
