DYNAPAC CA510D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA510D is a single drum vibratory smooth drum roller designed for heavy compaction tasks such as road shoulders, trenches, and repair work. It has a maximum operating mass of 18,500 kg and an operating weight of 18,300 kg including ROPS. The unit features an 83.9-inch wide smooth drum with centrifugal forces of 317 kN (71,265 lbs) at high amplitude and 231 kN (51,931 lbs) at low amplitude, with nominal amplitude values of 1.8 mm and 1.1 mm respectively. The vibratory frequencies are 29 Hz and 31 Hz, ensuring effective soil and asphalt compaction. Powered by a Cummins 6BTAA5.9-C170 Tier 2 turbocharged water-cooled diesel engine delivering 170 hp at 2,200 rpm, the CA510D provides reliable and efficient power. It has a fuel capacity of 84.6 gallons and a maximum speed up to 11 mph (18 kph). The roller boasts a theoretical gradeability of 43%, a maximum steering angle of 38 degrees, and vertical oscillation of ±9° for optimal maneuverability on uneven terrain. The hydraulic system includes axial piston pumps and motors with variable displacement, allowing precise driving, steering, and vibration control. Safety features include a failsafe multi-disc brake system located both in the drum gearbox and rear axle. Tires are sized 23.1x26 with 8-ply rating. The overall width is approximately 7.8 ft, with a height of 7.2 ft to the roller frame and 9.7 ft to the top of the ROPS/FOPS, providing durability and operator protection in tough job site conditions.
