DYNAPAC CA624 HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA624 HF is a heavy-duty static smooth drum roller designed for efficient asphalt and soil compaction. It features an 84-inch (approximately 2130 mm) drum width with a drum diameter of 51.2 inches, providing a broad compaction surface and effective static linear load distribution. The roller is powered by a Cummins QSB 4.5 T3 turbocharged, water-cooled diesel engine, delivering approximately 125 hp at 2200 rpm, combining high power with fuel efficiency and reliability. It achieves vibration frequencies of 3,060 to 4,020 vibrations per minute, optimizing compaction force and surface finish. The CA624 HF has an operating width of 91 inches and a turning radius inside of 242 inches, enabling maneuverability on-site. The machine’s operating weight is around 27,778 pounds, providing the mass required for deep compaction. Hydraulic systems incorporate dual axial piston pumps and motors for driving and vibration, while hydrostatic service brakes and failsafe multi-disc parking brakes ensure operator control and safety. Its fuel capacity is 63.5 gallons, supporting long operational shifts. Key dimensions include an overall length of 16.38 feet, width of 7.61 feet, height to cab top of 9.81 feet, wheelbase of 12.11 feet, and ground clearance of 12.21 inches. The maximum speed is approximately 7.5 mph. The CA624 HF’s centrifugal force peaks at nearly 38,000 pounds during high amplitude vibration, making it suitable for demanding compaction tasks on large-scale paving and construction projects. This roller combines robust engine performance, precise vibration control, and durable structural design for superior compaction efficiency in asphalt and granular layers.
