STONE DD29 STATIC SMOOTH DRUM ROLLER

Technical Description

The Stone DD29 is a smooth drum roller designed for efficient compaction tasks with a drum width of 49.2 inches and an operating width of approximately 53.7 inches, enabling effective coverage on asphalt and soil surfaces. It operates with a vibration frequency of 66.7 vibrations per minute (vpm), delivering reliable compaction force. Powered by a Kubota V2203M Tier 4A diesel engine, the roller produces a net power of 44 hp, ensuring robust and efficient performance that meets stringent emissions standards. The engine is a vertical, water-cooled, 4-cylinder unit with a displacement of 2.197 liters, designed for durability and low noise output. The DD29 roller weighs 6,335 pounds and carries 18 gallons of fuel capacity and a 22.4-gallon hydraulic fluid system, supporting extended operation with minimal downtime. It has a maximum travel speed of 6.6 mph, facilitating efficient site movement. The drum diameter is 28.9 inches with a nominal medium amplitude of 0.016 inches and produces a centrifugal force of 7,193.9 pounds, delivering consistent and effective compaction force across various applications. The hydraulic and vibration systems are engineered for optimal control and smooth operation on compacting tasks for asphalt pavements and granular sub-base materials. The Stone DD29 smooth drum roller balances power, compaction efficiency, and operational flexibility for construction and road maintenance projects.
