The Dynapac CA150D is a static smooth drum roller designed for efficient compaction with high operational performance. It features a single 48-inch diameter, 66-inch wide smooth drum with a 0.9-inch thickness, delivering a static linear load of 382.7 pounds per inch. The drum’s vibration system operates at frequencies between 31 to 43 vibrations per minute (vpm) with a nominal amplitude of 0.1 inches, providing strong and consistent compaction force—with centrifugal forces of 33,721 lbs at high and 24,504 lbs at low settings. Powered by a Cummins QSB3.3 water-cooled turbo diesel engine, producing 80.5 hp (60 kW) at 2200 rpm, it ensures reliable and efficient performance. The roller has a maximum speed of 5 mph and a fuel capacity of 225 gallons, suitable for extended job site operation. It supports an impressive gradeability of 55%, allowing effective operation on inclined surfaces. The overall machine dimensions include a length of approximately 188 inches, a width of 6.1 feet, and a height of 6.8 feet to the frame and 9.3 feet to the top of the cab or ROPS/FOPS structure. The operating weight is around 20,283 lbs, with reduced weight in ROPS-only configuration (approximately 15,873 lbs). Equipped with 420-70B24 tires, the CA150D combines stable driving and compaction performance to accommodate various construction and paving projects requiring smooth asphalt or granular soil compaction.
