DYNAPAC CA144 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA144 is a static smooth drum roller designed for efficient compaction in trenches, roadworks, and confined spaces. It features a 66-inch wide drum with a diameter of 39.4 inches, optimized to provide a nominal amplitude of 0.1 inches and a centrifugal force of 20,008 pounds at a vibration frequency of approximately 2,100 to 2,300 vibrations per minute (35 to 38 Hz). The roller delivers a gross power of 84 horsepower, enabling a maximum travel speed of 3.8 mph. It has an operating weight of 10,582 pounds, ensuring adequate ground contact for effective soil compaction. The machine measures 12.99 feet in length, 4.57 feet in width, and stands 8.23 feet tall to the top of the cab, with a wheelbase of 6.1 feet and ground clearance of 9.57 inches. Its fuel tank holds 31 gallons, supporting extended operation periods. The smooth drum with drum drive design provides excellent maneuverability even on steep slopes, making it suitable for a variety of soil types where even, static compaction is required. This model balances power, size, and precision for versatile compaction applications, particularly in confined or trench environments.
