DYNAPAC CA301 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA301 is a static smooth drum roller designed for efficient compaction in road construction, airfields, dams, and similar infrastructure projects. It features an 84-inch (2137 mm) wide smooth drum and an inside turning radius of 148 inches (3.76 m), allowing for precise maneuverability. Driven by a Cummins engine delivering 107.29 hp (80 kW) at 2400 rpm, the CA301 provides robust power and fuel efficiency with a 70-gallon (265 L) fuel tank and 7.1 gallons (27 L) of coolant capacity. The roller achieves a vibration frequency between 1800 and 1980 vibrations per minute (vpm) for enhanced compaction effectiveness. Its operating mass is approximately 25,022 lbs (11,350 kg), with a maximum operating mass of 26,015 lbs (11,800 kg), producing a static linear load of 176.96 lbs/in (31.5 kg/cm). The unit supports a maximum theoretical gradeability of 40%, and a vertical oscillation of ±9°, enabling it to handle uneven terrain with stability. It has a speed range from 0 to 14.3 mph (0 to 23 km/h), suitable for both operational and transportation movements. The machine’s mass distribution is managed efficiently with front and rear modules weighing 14,793 lbs (6,710 kg) and 10,229 lbs (4,640 kg), respectively. Additional features include an automatic parking brake applied when the engine stops or hydraulic pressure is lost for improved safety. This model is designed for high-rate compaction of asphalt, concrete, base, and subbase courses with reliable responsiveness and operator control.
