SAKAI SW504 STATIC SMOOTH DRUM ROLLER

Technical Description

The 2020 Sakai SW504 Static Smooth Drum Roller is a robust compaction machine designed for medium-duty asphalt and soil compaction tasks. It features dual 51" wide by 31" diameter smooth drums mounted on a heavy-duty center hitch with excellent side and curb clearance, enabling efficient maneuvering in confined spaces. The machine weighs 8,955 lbs and operates with a powerful 43 HP Kubota D1803 Final Tier 4 diesel engine, delivering reliable power and compliance with emissions standards. The hydrostatic drive system powers both drums independently, providing smooth, controllable traction and vibration. The drums employ independent vibration with a frequency of 3,300 vibrations per minute (VPM), producing centrifugal forces of 5,955 lbs on low and 7,710 lbs on high settings with nominal amplitudes of 0.011" and 0.014", respectively, ensuring effective compaction. Operator controls are conveniently located on an instrument panel, simplifying operation. Vibration isolation is achieved via durable rubber mounts, enhancing machine longevity and operator comfort. The roller includes an 81.9-gallon water tank with triple-filtered spray nozzles for drum wetting to prevent asphalt sticking. Stopping power is provided by a combination of hydrostatic service brakes, SAHR parking brakes, and a combined footbrake for safety and reliability. Standard lighting and sound safety features improve operational visibility and alertness in job site environments. Overall, the SW504 strikes a balance between power, durability, ease of use, and environmental compliance for reliable paving and compaction in commercial and municipal applications.
