The Dynapac CA150A is a static smooth drum roller designed for robust compaction tasks in road construction and related applications. It features a single smooth steel drum with a width of 66 inches (1.68 meters) and a diameter of 48 inches (1219 mm), providing an effective compaction width of approximately 5.5 feet. The drum operates at a vibration frequency of 45 vibrations per minute (vpm), delivering a static linear load of about 22.1 kg/cm, suitable for medium to heavy compaction requirements. Powered by a reliable John Deere or Cummins tier 3 3.3-liter, 4-cylinder, water-cooled turbo diesel engine, the CA150A produces 80 hp at 2200 rpm, ensuring efficient performance and fuel management with a 59.4-gallon (225 L) tank capacity. The machine’s operating mass ranges between 16,314 lbs (7,400 kg) and 16,755 lbs (7,600 kg), with a maximum operating mass reaching up to 18,298 lbs (8,300 kg) depending on configuration. It offers a compact footprint with an overall length of 15.67 feet (4776 mm), width of 5.5 feet (1852 mm), and an inside turning radius of 9 feet, enabling maneuverability on various sites. The roller’s maximum theoretical gradeability is between 40% and 55%, allowing effective operation on inclines. Equipped with robust 13.00-24, 8-ply tires, and capable of speeds up to 7.5 mph (3.1 mph), the CA150A combines power, stability, and precision for consistent, high-quality smooth asphalt or soil compaction. Its ROPS (Rollover Protective Structure) enhances operator safety during operation. This machine is optimized for medium to large-scale pavement and base compaction projects where smooth, static compaction is required.
