SAKAI SW790 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW790 Static Smooth Drum Roller is engineered for efficient compaction with an overall width of 7 feet and a drum width of 84 inches, making it well-suited for asphalt and soil compaction in road construction and industrial projects. It operates at a frequency of 50 vibrations per minute (vpm), providing smooth and uniform density across surfaces. The machine features an Isuzu 4JJ1XDIA engine, a reliable 3.0-liter, inline 4-cylinder diesel powerplant with direct high-pressure common rail fuel injection and turbocharging. This engine delivers robust performance with approximately 95 kW (127 HP) and ensures consistent power output, optimized fuel efficiency, and reduced emissions. The roller’s empty weight with rollover protective structure (ROPS) is approximately 28,085 pounds, contributing to its substantial static compaction force. Sakai’s patented technologies, such as durable rubber isolators for the drum and a high-reliability sprinkler system with anti-clog features, enhance operational reliability and ease of maintenance. The articulated center-pin joint provides excellent maneuverability and stability, while safety is assured with a standard emergency brake pedal. Designed with operator comfort and visibility in mind, the SW790 offers a full view of the drum surface and edge. Suitable for highway paving, commercial parking lots, and large infrastructure projects, the SW790 combines powerful engine performance, robust chassis construction, and advanced compaction capabilities for high-quality, smooth surface finishes.
