DYNAPAC CA512D STATIC SMOOTH DRUM ROLLER

The Dynapac CA512D is a high-performance static smooth drum roller designed for effective compaction in road construction and soil stabilization. It features a robust John Deere QSB 6.7 T3 water-cooled turbo diesel engine with aftercooler, delivering 173 hp (129 kW) at 2200 rpm. The roller operates at a maximum speed of 6.9 mph (10 kph) and has a fuel capacity of 84.6 gallons, supporting extended operation times. The CA512D has an operating weight of approximately 34,392 lbs (15,700 kg), providing a strong static load for compaction. Its drum specifications include an 83.9-inch width and 61.6-inch diameter, equipped to exert centrifugal forces of 53,504.6 lbs at low frequency and 67,442.7 lbs at high-frequency vibration, with vibration frequencies ranging between 29 and 33 vibrations per minute (vpm). Both nominal vibration amplitudes are 0.1 inches, optimizing soil consolidation. Dimensions include a ground clearance of 17.8 inches, an overall width of 7 feet, and a length of 19.7 feet. The turning radius inside measures 10.5 feet, facilitating maneuverability on site. The wheelbase is 9.9 inches, and the machine rests on robust 23.1x26 tires. This model is engineered for durability and efficiency in medium to large-scale compaction tasks, combining power, stability, and precise vibration control for reliable performance in diverse ground conditions. Its static smooth drum optimizes surface finishing while minimizing ground disturbance.
