DYNAPAC CA511 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA511 Static Smooth Drum Roller is a heavy-duty compaction machine designed for efficient soil and asphalt compaction. It features a robust 84-inch wide smooth steel drum that applies uniform static pressure over a large surface area. Powered by a Deutz BF6L 913 turbocharged 6-cylinder diesel engine, it delivers 154 hp (115 kW) with a displacement of 6.128 liters, ensuring reliable high torque and fuel-efficient operation suitable for demanding compaction tasks. The engine's rated speed is approximately 2800 rpm, with a torque output of 510 Nm at 1700 rpm. The CA511 has an operating mass of about 33,510 lbs (15,200 kg), with a maximum operating mass near 34,360 lbs (15,590 kg), providing substantial weight for effective compaction force. Its turning radius is 130 inches inside, allowing maneuverability on varied job sites, while its operating width measures 95.5 inches. The drum vibrates at frequencies between 1,620 and 1,920 vibrations per minute, enhancing compaction capability on cohesive and granular materials. Fuel capacity is 70 gallons (265 liters), enabling extended operation without refueling. The machine offers a maximum theoretical gradeability of 47%, facilitating operation on moderately steep surfaces. Equipped with advanced hydraulic systems for traction, vibration, steering, and braking, the Dynapac CA511 combines power, precision, and durability for medium to large-scale earthwork and road construction projects. Its design supports reliability and ease of maintenance in challenging construction environments.
