DYNAPAC CA280/300 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA280/300 static smooth drum roller is designed for high-efficiency compaction with a drum width of 83.9 inches (2130 mm) and a drum diameter of 60 inches (1524 mm). It operates with a vibration frequency of 33 Hz and delivers nominal amplitudes of 0.1 inches for both high and low settings, producing centrifugal forces of 55,303 lb (high) and 26,752 lb (low). Powered by a QSB 4.5 engine delivering 110 hp at 2200 rpm, it ensures reliable performance for demanding construction tasks. The roller's operating weight is approximately 27,117 lb (12,300 kg), providing strong static linear load for effective soil and asphalt compaction. The machine measures 18.21 feet in length, 6.99 feet in width, and 9.69 feet in height to the top of the cab, with a wheelbase of 9.45 feet and ground clearance of 15.75 inches. It supports a fuel capacity of 66.1 gallons and a maximum speed of 4.7 mph, balancing power, weight, and maneuverability for smooth compaction across various surfaces. This model is part of Dynapac’s range of smooth drum rollers suitable for medium to large compaction projects, combining durable engineering with operational efficiency.
