DYNAPAC CC522C STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC522C is a high-performance vibratory smooth drum roller designed for efficient compaction in road construction and other infrastructure projects. It features a 55.2-inch diameter steel drum with a width of 76.8 inches, delivering a static linear load of 455.2 pounds per inch to ensure optimal compaction force. The machine operates at a vibration frequency of 51 vibrations per minute, with a nominal amplitude of 0.1 inches at both high and low settings. Centrifugal forces are 31,024 lbs on high and 15,737 lbs on low to enhance compaction efficiency. Powered by a Cummins 4AA BT3.9-C engine, the roller produces 124.8 horsepower at 2200 rpm, offering robust performance and reliability. It reaches a maximum speed of 6.9 mph, balancing compaction quality with operational efficiency. The CC522C has an operating weight of approximately 25,794 pounds, a height of 10 feet to the top of the cab, an overall length of 16.7 feet, and a width of 6.9 feet, facilitating stability and ease of maneuverability on job sites. This model is suited for asphalt and soil compaction where smooth surface finishing is critical, combining powerful vibration, static load, and durable construction for consistent results. Its articulated steering and vibration on both drums increase versatility and control, making it a preferred choice for medium to large compaction applications.
