DYNAPAC CA2500D (3.3) STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA2500D (3.3) is a static smooth drum roller engineered for medium to heavy-duty compaction tasks on base and subbase courses including rockfill and granular soils. Powered by a water-cooled, turbocharged Cummins QSB3.3 diesel engine delivering 110 hp at 2200 rpm, it combines engine efficiency with robust compaction performance. The machine features an 83.9-inch wide smooth steel drum with a diameter of 59.1 inches and thickness of 1 inch, capable of generating a centrifugal force of up to 46,086 lbs in high vibratory mode and 22,481 lbs in low mode, with a nominal amplitude of 0.1 inches. Its static linear load is 145.6 pounds per inch, providing effective compactive effort over a wide surface area (84 cubic inches pad surface area). Designed for excellent maneuverability and operational safety, the CA2500D offers a curb clearance of 17 inches, ground clearance of 12.6 inches, and a gradeability of 51%, enabling it to work efficiently on challenging slopes. The heavy-duty rear axle and hydrostatic driving system ensure reliable traction and smooth operation at speeds up to 8 mph. The roller’s dimensions (overall length 218.9 inches, height to top of ROPS 9.3 feet, wheelbase 111.9 inches) and turning radii (inside 10.2 ft, outside 17.8 ft) allow precise handling on site. With a fuel capacity of 190 gallons and an operating weight near 22,928 lbs, the CA2500D balances power, endurance, and operator comfort for extended compaction applications. Standard safety and ergonomic features include ROPS/FOPS protection and a hydraulically controlled system ensuring durability and operational efficiency on diverse compaction projects.
