DYNAPAC CA121D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA121D is a static smooth drum roller designed for efficient soil and asphalt compaction in confined or medium-scale projects. It features a single smooth drum measuring 37.1 inches in diameter and 53.8 inches in width, delivering a centrifugal force of 12,139.7 lbs at medium amplitude with a nominal amplitude of 0.1 inches. The roller provides a static linear load of 216.2 pounds per inch, ensuring consistent compaction quality. Powered by a reliable e 3029 TF engine producing 71.1 horsepower (53 kW), the CA121D reaches a maximum speed of 3.8 mph (5 kph), suitable for precise and controlled compaction tasks. The machine's operating weight is approximately 9,149 lbs, with compact dimensions including an overall length of 11.8 feet, a width of 4.9 feet, and a height of 7.7 feet to the top of the cab, enabling operation in limited spaces. Vibration frequency is set at 32 vibrations per minute, optimizing soil particle rearrangement during compaction. Its robust build and ergonomic design target trench compaction, road shoulders, and other restricted areas requiring static smooth drum operation. The CA121D combines maneuverability, power, and effective compaction, making it suitable for construction and maintenance activities involving soil stabilization and asphalt surface preparation. Overall, the Dynapac CA121D offers a balanced blend of power, efficiency, and precision for compaction applications.
