DYNAPAC CA280D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA280D is a static smooth drum roller designed for heavy-duty compaction tasks. It features a single steel drum with a diameter of 60 inches and width of 83.9 inches, delivering powerful compaction performance. The roller generates a high centrifugal force of 55,303 lbs and a low force of 26,752 lbs, with a nominal amplitude of 0.1 inches and vibration frequency of 33 vpm, ensuring optimal soil and asphalt densification. Powered by a water-cooled turbocharged diesel engine (Cummins QSB 4.5), it produces 110 hp at 2200 rpm, enabling consistent operation and fuel efficiency with a 66.1-gallon fuel tank. The machine’s operating weight is approximately 27,558 lbs, providing substantial downward pressure for effective compaction. It has a maximum speed of 3.2 mph and a wheelbase of 9.5 ft to support maneuverability on construction sites. Dimensionally, the CA280D stands 9.7 ft tall to the top of the cab, with an overall length around 18.3 ft, width of 7 ft, and ground clearance of 15.8 in. It rides on large 23.1x26 tires to accommodate uneven terrain. The robust design and its static smooth drum configuration make the Dynapac CA280D suitable for compacting granular and mixed soils on roads, highways, and infrastructure projects where static rolling is preferred over vibratory action. This model offers proven reliability, efficient compaction, and operator comfort, fitting medium to large-size compaction applications.
