The Dynapac CA144 D is a vibratory smooth drum roller engineered for compaction in trenches, road shoulders, and confined spaces, particularly effective in refilling work. It features a 66-inch wide smooth drum with a 39-inch diameter and 0.87-inch drum shell thickness, delivering a vibration frequency of 2100 vpm (35 Hz) and a centrifugal force of 20,008 lbs at nominal medium amplitude of 0.1 inches. The machine weighs 10,600 lbs operating mass, with a maximum mass of 13,000 lbs, and exerts a static linear load of 68 lbs/in. Its compact design includes an inside turning radius of 88 inches, an overall width of 71 inches, and a length of approximately 155.5 inches, facilitating maneuverability in tight work areas. Powering the CA144 D is a robust John Deere 5030 TF270 diesel engine producing 84 hp at 2800 rpm, fueled by a 31-gallon tank, ensuring efficient and reliable operation. The roller’s max speed reaches 4 mph, and it boasts a wheelbase of 6.1 feet, ground clearance near 9.57 inches, and max theoretical gradeability of 46%. The ROPS height measures about 98.7 inches, while tire size is 12.5-20. Designed for versatility and durability, the CA144 D excels in compacting various soil types on roads, pipelines, and restricted job sites with consistent vibration and static load performance to optimize soil density and stability. Its vibration and drum specifications enable effective compaction with good accessibility even on slopes, making it suitable for repair work on dams, car parks, and airfields.
