DYNAPAC CC334HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC334HF is a static smooth drum roller engineered for efficient asphalt and soil compaction in medium to large-scale projects. It features a 68-inch wide drum with a diameter of 45 inches and a shell thickness of 0.7 inches, delivering uniform compaction. The machine operates at two vibration frequencies, 2870 and 4010 vibrations per minute, enabling adaptability to different materials and compaction requirements. Powered by a Cummins engine rated at 100 hp at 2,200 rpm, the CC334HF combines robust performance with fuel efficiency, supported by a 34-gallon fuel tank. Its operating width ranges from 73.5 to 74 inches, and it possesses a maximum operating mass of 21,800 pounds, providing substantial ground contact for effective compaction. The static linear load of 146 pounds per inch on both front and rear drums contributes to its high compaction force. The roller has a compact turning radius inside of 195 inches, enhancing maneuverability on confined job sites. Designed for challenging terrains, it offers a maximum theoretical gradeability of 35% and vertical oscillation of ±7°, ensuring stability and consistent contact with uneven surfaces. The front and rear modules each weigh 9,900 pounds, evenly distributing weight to optimize performance. This model embodies Dynapac's focus on operator comfort, ease of handling, and durability, making it a reliable choice for contractors seeking a powerful and steady smooth drum roller for road construction and maintenance applications.
