DYNAPAC CA250 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA250 static smooth drum roller is a heavy-duty compaction machine designed for efficient soil and asphalt compaction. It features a robust 110 hp water-cooled turbo diesel engine (QSB 4.5) with aftercooler, delivering power at 2200 rpm. The roller’s operating weight is approximately 23,369 lbs, providing excellent ground contact force. The smooth steel drum measures 60 inches in diameter and 83.9 inches in width, ensuring wide coverage per pass. It generates a high centrifugal force of 55,303 lbs and a low centrifugal force of 26,752 lbs, with a nominal vibration amplitude of 0.1 inch, operating at a frequency of 33 vibrations per minute. The machine has a ground clearance of 15.8 inches and an overall width of 7 feet, with the height to the top of the cab at 9.7 feet and an overall length of 18.3 feet. The wheelbase is 9.5 feet, and tires are sized 23.1x26. Fuel capacity is 66.1 gallons, supporting extended operation without frequent refueling. The maximum speed is 4.7 mph, emphasizing controlled, steady compaction efforts. This heavy roller is particularly suited for large-scale road building, industrial sites, and other infrastructure projects requiring smooth, dense surfaces. Its durable construction and engine power make it reliable for continuous, high-quality compaction work in varied environments.
