DYNAPAC CA512 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA512 is a medium-heavy static smooth drum roller designed primarily for soil compaction and rock fill applications. It features an 84-inch (approx. 83.9 in) smooth drum with a diameter of 61.6 inches, providing an operating width of 93 inches. The roller is equipped with a Cummins QSB6.7 T3 engine, delivering 173 horsepower at 2200 rpm to ensure reliable and efficient power output. The vibration system operates at dual frequencies of 1,740 and 1,980 vibrations per minute (29 Hz and 33 Hz), allowing adjustable compaction force with a high centrifugal force of 67,442.7 pounds. The machine’s substantial operating weight of approximately 34,392 pounds (15,700 kg) enhances its compaction effectiveness. Its design includes an inside turning radius of 126 inches and a maximum theoretical gradeability of 56%, making it capable of maneuvering on challenging job sites. The Dynapac CA512 has an overall width near 7 feet and a height to the top of the cab of about 9.7 feet, ensuring operator comfort and visibility. Fuel capacity is 84.6 gallons, supporting extended operation times, and its maximum speed reaches around 6.9 mph, suitable for both transport and work phases. Additional mechanical features include ±9° vertical oscillation to maintain ground contact on uneven terrain. The Dynapac CA512 is engineered for efficient, deep compaction across base and subbase courses, with optional cab features and accessory compatibility such as compaction meters and speed recorders for enhanced operational control.
