DYNAPAC CA250D (BRAZIL) STATIC SMOOTH DRUM ROLLER

The Dynapac CA250D (Brazil) is a static smooth drum roller designed for robust soil compaction applications. It features a large smooth steel drum with a diameter of 60 inches and width of 83.9 inches, with a shell thickness of 1 inch, delivering a static linear load of 162.4 pounds per inch, ensuring effective compaction performance. The drum develops a high centrifugal force of approximately 55,078 lbs and a low centrifugal force of about 26,752 lbs, both at a nominal amplitude of 0.1 inches for precise compaction control. Powered by a Cummins QSB 4.5 Tier 3 water-cooled turbo diesel engine, the CA250D generates 110 hp at 2200 rpm, providing ample power for demanding grading and soil stabilization tasks. The roller's operating weight is around 26,015 lbs, with a fuel capacity of 250 gallons, supporting long operational cycles without frequent refueling. It achieves a maximum speed of 7.5 mph and gradeability up to 65%, suitable for steep and uneven terrains. The machine offers a wheelbase of 113.4 inches and a tight turning radius (10.2 ft inside), enhancing maneuverability on job sites. Ground clearance is 17.9 inches with curb clearance at 15.8 inches, allowing navigation over obstacles. The roller’s overall height is 7.2 feet (9.7 feet including ROPS/FOPS), and its tire size is 23.1 x 26. Overall, the Dynapac CA250D combines strong compaction capabilities, efficient powertrain, and durable construction, optimized for high productivity in soil compaction applications commonly found in road construction, embankments, and infrastructure projects.
