DYNAPAC CA302DCO STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA302DCO is a static smooth drum roller engineered for medium to heavy compaction tasks. It features a 60.8-inch diameter and 83.9-inch wide steel drum, delivering a centrifugal force of approximately 58,450 lbs at a nominal amplitude of 0.1 inch with a vibration frequency of 28 vibrations per minute, ideal for asphalt and granular base compaction. Powered by a Cummins QSB 4.5 water-cooled turbo diesel engine with an aftercooler, it produces 125 hp, ensuring efficient operation. The roller has an operating weight of 28,109 lbs and a maximum speed of 5.6 mph. Its dimensions include a ground clearance of 15.8 inches, overall length of 18.3 feet, width of 7 feet, height to the top of the cab at 9.8 feet, and a wheelbase of 9.5 feet. It is equipped with 23.1x26 tires providing excellent traction and stability. Fuel capacity is 66.1 gallons, supporting extended operation. The hydrostatic drivetrain employs axial piston pumps and motors for both driving and vibration control, enabling smooth and responsive maneuvering. Safety features include a failsafe multi-disc braking system in the drum gearbox and rear axle. The roller's heavy static linear load and broad drum width make it suitable for large-scale road construction, site preparation, and asphalt compaction projects requiring high uniform density and smooth surfaces. Overall, the Dynapac CA302DCO combines powerful engine performance, robust build, and advanced vibration control to deliver reliable, effective compaction in diverse construction environments.
