DYNAPAC CA270D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA270D is a heavy-duty static smooth drum roller designed for efficient soil compaction in demanding applications such as road construction, airfields, dams, and industrial sites. It features a powerful Cummins 4BT 3.9 102C water-cooled turbocharged engine with intercooler delivering 102 hp at 2300 rpm. The machine has a substantial operating weight of approximately 26,676 lbs, providing a static linear load of 184.8 pounds/inch for effective compaction. Its single smooth drum measures 60 inches in diameter, 1 inch thick, and 83.9 inches wide, offering excellent ground contact. The roller achieves a maximum centrifugal force of 55,753 lbs at high amplitude with a nominal amplitude of 0.1 inches, suitable for deep and uniform compaction without causing material displacement. It has a wheelbase of 113.4 inches and a turning radius inside/outside of 10.2 ft / 17.8 ft, ensuring good maneuverability on-site. The operator’s station is protected by ROPS/FOPS at a height of 9.7 ft, with overall machine height at 7.2 ft without the protective structure. Ground clearance and curb clearance are 17.9 inches and 19.5 inches, respectively, enhancing versatility over rough terrain. Fuel capacity is 250 gallons, supporting extended work periods, and the roller’s max travel speed is 6.3 mph. The machine's gradeability of 57% enables operation on steep inclines. Tires measure 23.1 x 26, complementing the smooth drum for traction when required. Overall, the Dynapac CA270D combines robust power, precise compaction capability, and durability for heavy construction demands.
