DYNAPAC CA251 STATIC SMOOTH DRUM ROLLER

The Dynapac CA251 is a heavy-duty static smooth drum roller designed for efficient compaction of roads, airfields, dams, and similar construction projects. It features an 84-inch-wide drum and operates at a width of 93 inches, providing a static linear load of 133.28 lbs/in to ensure high compaction quality. The roller's turning radius on the inside is 148 inches, facilitating maneuverability on-site. Powered by a choice of engines—standard Deutz F6L 912 delivering 107 hp at 2400 rpm, or an optional Cummins 6BT 5.9 producing 152 hp at 2400 rpm—it offers robust performance and adaptability to different job requirements. The CA251’s vibration system operates at frequencies between 1800 and 1980 vibrations per minute, aiding in asphalt and base course compaction. The machine's operating mass ranges from approximately 21,054 lbs (CECE) up to a maximum of 23,148 lbs, balanced with front and rear module weights of 11,155 lbs and 9,899 lbs respectively. It reaches speeds up to 14.29 mph and handles a theoretical maximum gradeability of 40%, suitable for varied terrain. The roller includes a fuel tank with a 70-gallon capacity and a compact hydraulic system (approx. 6.6 to 6.9 gallons). Dimensions measure roughly 211.8 inches in length and 85.6 inches in height, accommodating an 8-ply tire size of 23.1 x 26. The CA251 integrates safety features like ROPS and is engineered for ease of maintenance, making it a reliable choice for large-scale compaction tasks.
