The BOMAG BW 124 DH-40 is a robust single drum vibratory smooth drum roller designed for efficient compaction of granular and mixed soils. Powered by a reliable Deutz D2011 L03i 3-cylinder diesel engine, it delivers 44.3 hp (33 kW) at 2500 rpm, featuring air-oil cooling and meeting emissions level 3a/4i standards. The roller has a compact build with an overall length of 131.9 inches, width of 4.3 feet, and height to the top of the cab of 8.2 feet, plus a ground clearance of 12.6 inches providing excellent maneuverability. It features a 47.3-inch wide smooth drum with a diameter of 37.8 inches, producing a centrifugal force of up to 18,546.8 lbs at medium vibration and a nominal amplitude of 0.1 inches for precise compaction. The vibration frequency operates at 2460 vpm (vibrations per minute), ensuring effective soil compaction. The machine weighs approximately 7,275 lbs operating weight and has a maximum speed of 5.6 mph. Its hydrostatic steering system with oscillatory articulation and dual hydraulic travel pumps enhances control and gradeability, enabling it to manage slopes up to 55%. Braking is managed through hydromec parking brakes and hydrostatic service brakes for safety and responsiveness. Tires are 9.5-24 4PR, designed for stability on various surfaces. Fuel capacity is 15.9 gallons, supporting long operation periods. The BW 124 DH-40 combines compact design, powerful engine, and advanced vibration technology for versatile, reliable soil compaction on small to medium-sized sites with excellent operational efficiency and ergonomics.
