DYNAPAC CA144D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA144D Static Smooth Drum Roller is a single-drum vibratory compactor designed for efficient soil and asphalt compaction in medium-duty applications. It features a 66-inch wide smooth steel drum with a 39.4-inch diameter, providing consistent ground contact and uniform compaction across the full drum width. The roller delivers a medium centrifugal force of 20,008 lbs at a vibration frequency of 35 vpm and a nominal amplitude of 0.1 in, enabling effective compaction of granular and cohesive soils as well as asphalt layers. Power is supplied by a John Deere 5030HF285 water-cooled turbo diesel engine with aftercooler, rated at 84 hp (63 kW) at 2,800 rpm, ensuring reliable performance and durability under demanding job site conditions. The machine has an operating weight of 10,582.2 lbs, contributing to high static linear load for improved compaction results. It offers a maximum travel speed of 3.8 mph (5 km/h) and a fuel tank capacity of 31 gallons for extended operating cycles. With a ground clearance of 9.6 inches, an overall width of 4.6 feet, and a tight turning radius, the CA144D provides good maneuverability in confined areas. Standard tires are 12.5-20, supporting stable operation on varied terrain. This model is well-suited for road construction, base work, and asphalt finishing where precision and consistent compaction are required.
