DYNAPAC CA252D STATIC SMOOTH DRUM ROLLER

The Dynapac CA252D is a medium-range vibratory smooth drum roller designed for efficient compaction of base and subbase courses in road construction and earthworks. It features a single smooth steel drum with a diameter of 60 inches (1,523 mm) and a width of 83.9 inches (2,130 mm), providing a wide compaction surface. The roller delivers a high centrifugal force of 55,303 lbs (246 kN) at a nominal amplitude of 0.1 inches (1.7 mm), enabling effective soil and asphalt compaction, with a low amplitude force of 26,752 lbs (119 kN) for precision tasks. Vibration frequency is set at 33 vibrations per minute (Hz), enhancing compaction efficiency. Powered by a Cummins QSB 4.5 water-cooled turbo diesel engine with aftercooler, it produces 125 hp (93 kW) at 2200 rpm, ensuring robust performance. The roller operates at a maximum speed of 5.6 mph (8 kph) and has an operating weight of approximately 23,016 lbs (10,700 kg), balancing power and maneuverability. It is equipped with 23.1x26 tires for effective traction. The machine features an operator cab standing 9.8 feet tall, with 15.8 inches ground clearance and an overall length of roughly 18.3 feet and width of 7 feet, designed for operational comfort and site accessibility. Fuel capacity is 66.1 gallons (250 liters), allowing extended working hours between refueling. Hydrostatic service and parking brakes, along with axial piston hydraulic systems for driving, steering, and vibration functions, ensure responsive control and safety on job sites. The Dynapac CA252D is optimized for reliability and versatility in diverse compaction applications.
