DYNAPAC CA260 D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA260 D is a heavy-duty smooth drum roller engineered for efficient soil and asphalt compaction. Featuring an 84-inch (2130 mm) wide smooth steel drum with a 60-inch (1523 mm) diameter and 25 mm shell thickness, it delivers uniform compaction over a 94-inch operating width. The roller incorporates a single vibratory system operating at 1980 vibrations per minute (33 Hz), with a nominal amplitude of 0.1 inches, generating a maximum centrifugal force of approximately 55,303 lbs to optimize compaction depth and uniformity. Powered by a reliable Cummins QSB 6.7 water-cooled turbo diesel engine producing 150 hp at 2200 rpm, the CA260 D balances power and fuel efficiency with an 84.6-gallon fuel capacity. Its compact turning radius of 122 inches and overall dimensions—approximately 18.9 ft length, 6.99 ft width, and 9.69 ft height to the cab top—enhance maneuverability on tight construction sites. The machine’s operating weight is about 24,912 lbs, contributing to its effective static linear load for deep compaction. Additional features include a wheelbase of 9.42 ft, ground clearance of 15.75 inches, and 23.1x26 tires suitable for stable traction. It reaches a maximum travel speed of 5.6 mph. The Dynapac CA260 D combines robust vibration capability, powerful engine performance, and optimal dimensions, making it well-suited for a wide range of earthworks and paving applications requiring consistent, high-quality surface compaction.
