DYNAPAC CA4000D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA4000D is a robust static smooth drum roller designed for heavy compaction applications. It features a single vibratory drum measuring approximately 60 inches in diameter and 84 inches in width, with a drum shell thickness of 1.4 inches, delivering a high centrifugal force of up to 60,700 lbs and a nominal amplitude of 0.1 inches for efficient soil and asphalt compaction. The roller has an operating weight of about 32,850 lbs, with a static linear load of 229.6 pounds per inch, ensuring deep, uniform compaction. Powered by a Cummins QSB4.5 water-cooled, turbocharged engine with intercooler, the CA4000D generates 160 hp at 2200 rpm, providing reliable power for demanding tasks. It has a fuel capacity of 71.9 gallons and can reach a maximum speed of 7.5 mph, optimizing job site productivity. Key machine dimensions include a wheelbase of approximately 118 inches, overall length near 236 inches, ground clearance around 17.8 inches, and a height with ROPS/FOPS of 9.5 feet. The machine supports a 57% gradeability and features a turning radius of 10.9 ft inside and 18.4 ft outside, facilitating maneuverability in confined spaces. Equipped with hydrostatic drive in forward and reverse and multidisc fail-safe brakes, the CA4000D ensures precise control and operator safety. Its padfoot features a pad height of 4.1 inches and pad surface area of 22.7 square inches, enhancing compaction on cohesive soils. This model is suited for smooth finish applications, offering automatic vibration control and reliable performance across road construction and earthwork projects.
