DYNAPAC CC624 HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC624 HF is a high-performance vibratory smooth drum roller designed for efficient compaction in road construction and other heavy-duty applications. It features an 84-inch (2130 mm) wide steel drum with a diameter of 51.2 inches, capable of operating at vibration frequencies between 50 to 67 vibrations per minute (vpm). The drum delivers centrifugal forces up to approximately 37,993 lbs (169 kN) on the high amplitude setting, with a nominal amplitude of 0.1 inches for effective soil and asphalt compaction. Powered by a Cummins QSB 4.5 T3 turbocharged diesel engine, this machine produces up to 125 hp at 2200 rpm, offering robust and reliable propulsion with a maximum speed of 7.5 mph. Its hydrostatic drive system ensures smooth acceleration and precise control, with an exceptionally tight inside turning radius of 1.7 feet for enhanced maneuverability. The roller’s operating weight is around 27,778 lbs (12,600 kg), optimizing compaction pressure, while its 63.5-gallon fuel capacity supports extended operational periods. Other key dimensions include an overall width of 7 feet, height to the top of the cab of approximately 9.8 feet, and a wheelbase near 12 feet. The CC624 HF incorporates advanced hydraulic and vibration systems with axial piston pumps and driving motors, and a failsafe multidisc braking system integrated into both drums for reliable stopping power. Its ergonomic cab and optional asymmetric design improve operator comfort and visibility, making the Dynapac CC624 HF a versatile, efficient solution for heavy compaction tasks.
