DYNAPAC CA610D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA610D is a high-performance static smooth drum roller designed for heavy compaction tasks. It features a single smooth drum with a width of 83.9 inches (2130 mm) and a shell thickness of 50 mm, providing an effective compaction width of 2.13 meters. The roller has an operating weight of approximately 20,700 kg (46,297 lbs) with ROPS and a maximum operating mass up to 21,000 kg, optimized for stability and deep compaction of base and subbase materials. The machine is powered by a Cummins 6BTAA5.9-C170 turbocharged diesel engine delivering 127-129 kW (170-173 hp) at 2200 rpm, ensuring reliable performance and fuel efficiency with an 84.6-gallon fuel capacity. The CA610D offers adjustable vibration frequencies at 29 Hz and 31 Hz with nominal amplitudes of 1.8 mm (high) and 1.1 mm (low). It generates a centrifugal force of up to 71,265 lbs (317 kN) at high amplitude, enhancing soil and rockfill compaction. The static linear load reaches 66 kg/cm, contributing to effective compaction pressure. Its hydraulic system uses axial piston pumps and motors for precise driving and vibration control, complemented by a hydrostatic service brake and failsafe multidisc parking brake. Dimensionally, the roller measures 6.18 m in length, 2.4 m in width, with a height up to 3 m including ROPS. It achieves a gradeability of 43%, an inside turning radius of 3.2 m, and features a ground clearance of 17.8 inches, allowing maneuverability on uneven terrain. Tires are sized at 23.1 x 26 for optimized traction.
