DYNAPAC CA255 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA255 is a medium-heavy single drum vibratory smooth drum roller designed for efficient soil compaction in road construction, airfields, harbors, dam construction, and industrial sites. It features a robust 105 hp Kirloskar 4R1040TA3 water-cooled turbocharged engine with an intercooler, delivering power at 2200 rpm and a fuel capacity of 250 gallons for extended operation. The roller has an operating weight of approximately 26,676 lbs and a curb clearance of 19.5 inches, with a gradeability of 34% and ground clearance of 17.9 inches, allowing effective operation on varied terrains. The drum measures 60 inches in diameter and 83.9 inches wide, with a thickness of 1 inch. It produces a high centrifugal force of 55,303 lbs and a nominal amplitude of 0.1 inches, ensuring strong compaction performance. The static linear load is 173.1 pounds per inch, providing consistent pressure over the compaction width. Its maneuverability is supported by a wheelbase of 113.4 inches and turning radii of 10.2 ft inside and 17.8 ft outside. Hydraulically, it employs axial piston pumps with variable displacement for driving and vibration functions, combined with a hydrostatic service brake and failsafe multidisc parking brake on the rear axle. The roller's tires are sized 23.1 x 26. Operator safety is enhanced by ROPS/FOPS protection, with a height of 9.8 ft to the top of the structure. The Dynapac CA255 balances power, durability, and precision control, making it suitable for various medium to heavy compaction projects requiring smooth surface finishing.
