STONE SW990 STATIC SMOOTH DRUM ROLLER

Technical Description

The STONE SW990 Static Smooth Drum Roller is a heavy-duty compaction machine designed for asphalt and soil applications, featuring an 84-inch wide double drum that ensures efficient surface coverage. It operates with a vibration frequency range of 2,500 to 4,000 vibrations per minute, providing adjustable compaction force for various material types. Powered by a Deutz TCD2012L06-2V engine, this roller delivers reliable performance and durability. The machine’s operating width is 90 inches, and it boasts an inside turning radius of 172 inches, allowing for maneuverability in confined areas. Comparable models, such as the Sakai SW990, offer an operating weight of approximately 30,800 lbs, centrifugal force near 41,590 lbs, and engine power of 166 horsepower at 2400 rpm, which aligns with the STONE SW990’s robust engineering standards. The roller’s vibration amplitude ranges between 0.013 and 0.022 inches, optimizing compaction while minimizing surface damage. This combination of high vibration frequency and amplitude, along with substantial operational weight, makes it well-suited for achieving precise smoothness and density in paving and compaction tasks. Its design incorporates reliability, power, and versatility to meet demanding construction and asphalt applications.
