STONE SW320-I STATIC SMOOTH DRUM ROLLER

Technical Description

The STONE SW320-I is a static smooth drum roller designed for efficient compaction in construction and roadwork applications. It features a 47-inch wide steel drum that provides a 52-inch operating width, enabling broad and consistent surface coverage. The drum vibrates at a high frequency of 4000 vibrations per minute (vpm), optimizing soil and asphalt compaction for enhanced material stability. Its turning radius on the inside is 103 inches, allowing for agile maneuverability in confined workspaces. Powering the SW320-I is a Kubota D1703-M-ET01 diesel engine, a robust, water-cooled, 3-cylinder 4-cycle engine that meets International Tier IV emissions standards. This engine produces approximately 35 horsepower at 2800 rpm, combining high power output with reliability and fuel efficiency. The Kubota engine features indirect injection (E-TVCS), a compression ratio of 22.6:1, and advanced noise and vibration reduction technologies for smooth operation. The roller’s design balances power, efficiency, and operator control, making it suitable for compacting soil, gravel, concrete, and asphalt in a variety of infrastructure projects. The SW320-I’s compact dimensions and strong engine performance ensure both effective compaction and ease of use in diverse job site conditions.
