DYNAPAC CA250/260 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA250/260 static smooth drum roller is designed for heavy-duty compaction tasks with an 84-inch wide, 60-inch diameter smooth steel drum delivering effective surface consolidation. It operates with a vibration frequency of 33 Hz (1980 vpm), providing centrifugal forces of 55,303 lbs (high amplitude) and 26,752 lbs (low amplitude), both at a nominal amplitude of 0.1 inches, ensuring optimal compaction performance. Powered by a 110 hp water-cooled, turbocharged diesel engine (QSB 4.5 model), it runs at 2200 rpm and balances power and fuel efficiency with a 66.1-gallon fuel capacity. The roller weighs approximately 23,369 lbs and features dimensions conducive to maneuverability and stability: an overall length of 18.21 ft, width of 6.99 ft, height to cab top of 9.69 ft, wheelbase of 9.42 ft, and ground clearance of 15.75 inches. The roller’s tires measure 23.1x26 for robust traction. Its maximum speed reaches 4.7 mph, providing controlled operation on job sites. This smooth drum roller is optimized for asphalt and granular soil compaction in medium to large construction applications, delivering consistent density and surface smoothness with precise drum vibration and weight distribution.
