SAKAI DD38HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai DD38HF is a static smooth drum roller engineered for efficient asphalt and soil compaction. It features a 54.1-inch-wide steel drum with a diameter of 29.1 inches, operating at a vibration frequency of 70 Hz (vibrations per minute) to provide effective compaction with a nominal medium amplitude of 0.1 inches and generating a centrifugal force of 8,093 pounds. Powered by a robust Kubota V2203-M 4-cylinder, vertical, water-cooled, 4-cycle diesel engine, this unit delivers reliable performance with approximately 39.7 horsepower at 2800 RPM. The engine is naturally aspirated and designed for durability and fuel efficiency. The roller operates at a width of 54.1 inches and has an operating weight of about 8,400 pounds, contributing to high compactive effort. The fuel tank capacity is 18 gallons, supporting extended operation periods, while the hydraulic system fluid capacity is 22.4 gallons ensuring smooth hydraulic performance. The maximum travel speed reaches 6.3 mph, allowing for effective maneuverability on job sites, and the electrical system runs on a 12V operating voltage with a 40-amp alternator output. This model incorporates a proven hydrostatic drive system with articulated steering, delivering precision handling during compaction tasks. The DD38HF is well suited for medium-scale construction projects and infrastructure maintenance where consistent and smooth compaction is required. Its durable components and advanced vibration system optimize soil density while minimizing the risk of aggregate displacement or surface damage.
