SAKAI SW850-II STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW850-II Static Smooth Drum Roller is a heavy-duty compaction machine designed for efficient soil and asphalt compaction. It features a 79-inch wide smooth steel drum capable of operating at a vibration frequency ranging from 42 to 67 vibrations per minute (vpm), with a nominal frequency of 66.7 vpm, enabling effective compaction over a wide range of materials. The roller has an overall width of 6.6 feet and an impressively small inside turning radius of 14 inches, providing excellent maneuverability in confined spaces. Powered by a robust Deutz R2012L04-2V diesel engine, known for reliability and efficient fuel consumption, it delivers substantial power suitable for demanding compaction tasks. This engine is a 4-cylinder, inline turbocharged model with 4.0-liter displacement, operating at a maximum speed of 2400 rpm, balancing power and operational efficiency. The operating width of the roller is 7.3 feet, slightly wider than the overall width, maximizing ground coverage during compaction. This model is well-suited for large-scale construction jobs requiring stable vibration compaction and smooth surface finishing, ensuring durability and performance with minimal downtime due to easy engine maintenance. Its compact turning radius combined with its wide drum width allows it to operate effectively in both broad open areas and on tighter job sites, providing a versatile solution in the category of smooth drum rollers. The SW850-II maintains a solid reputation for dependable operation in road building and infrastructure projects.
