DYNAPAC CC422HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC422HF is a heavy-duty vibratory smooth drum roller designed for efficient compaction in road construction and similar applications. It features dual smooth steel drums, each 66.2 inches wide and 51.2 inches in diameter, delivering a high centrifugal force of 26,078 lbs and a low force of 16,636 lbs for precise compaction control. The roller operates with a nominal vibration amplitude of 0.1 inches at two vibration frequencies of 50 and 63 vibrations per minute, optimizing soil and asphalt density. Powered by a robust 124.8 hp (92 kW) 4AA BT3.9-C engine, it reaches a maximum speed of 6.9 mph. The machine has a static linear load of 479.4 pounds per inch, enhancing its compactive effort. Its operating weight is approximately 22,928 lbs, providing substantial downward pressure for effective surface leveling. The roller's articulated frame with a cab height of 9.8 feet and an overall length of 16.3 feet ensures operator comfort and maneuverability on job sites. This model combines powerful compaction capabilities with reliable performance, making it suitable for medium to large-scale asphalt or soil compaction projects where uniform surface density and smoothness are critical.
