SAKAI SW780HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW780HF is a double-drum static smooth roller designed for precise compaction tasks requiring high linear pressure without vibration. It features a drum width of 79 inches and an overall machine width of 7 feet, providing extensive coverage in a single pass. The drum operates at a static frequency range of 2,500 to 4,000 vibrations per minute (vpm). Powering the SW780HF is a robust Isuzu 4JJ1XDIA diesel engine, a 3.0-liter inline four-cylinder turbocharged and intercooled unit known for its durability and efficiency, providing reliable performance under demanding conditions. The engine offers a balance of power and fuel economy with a direct common rail injection system. This configuration makes the SW780HF suitable for applications like asphalt finishing, small to medium road construction projects, and situations where vibration is restricted or undesirable, such as thin lift compaction and finishing on sensitive surfaces. Its static smooth drum design ensures uniform compaction and a high-quality smooth finish on asphalt or granular base layers. The combination of a wide drum, high static linear pressure, and a dependable Isuzu engine makes this roller an effective choice for achieving optimal compaction density and surface smoothness in pavement construction and maintenance projects.
