DYNAPAC CA302D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA302D is a robust static smooth drum roller designed for efficient soil and asphalt compaction. Powered by a 125 hp (93 kW) water-cooled, turbocharged diesel engine (Cummins QSB 4.5), it operates at 2200 rpm, delivering reliable performance with a fuel capacity of 66.1 gallons. The roller features a large smooth drum measuring 83.9 inches wide and 60.8 inches in diameter, producing centrifugal forces of up to 67,443 lbs on high and 32,822 lbs on low settings, with a nominal amplitude of 0.1 inches and a vibration frequency of 33 vibrations per minute. It has an operating weight of approximately 27,999 lbs, ensuring adequate ground contact for effective compaction. The machine's dimensions include a ground clearance of 15.8 inches, an overall width of 7 feet, a wheelbase of 9.5 feet, and a cab height of 9.8 feet. Maximum travel speed is 5.6 mph (8 kph), supported by large 23.1x26 tires. The CA302D’s combination of controlled vibration and substantial centrifugal force makes it suited for heavy-duty compacting tasks on roadways, highways, and large construction sites requiring smooth, uniform soil or asphalt surfaces.
