STONE DD70 STATIC SMOOTH DRUM ROLLER

Technical Description

The Stone DD70 Static Smooth Drum Roller is a robust compaction machine designed for smooth, even surface finishing in roadwork and construction projects. It features a **57-inch wide smooth drum** that provides substantial ground contact for effective compaction. The drum operates at a vibration frequency of **55 vibrations per minute (vpm)**, enhancing soil and asphalt density by applying consistent vibratory force. The unit has an **operating width of 64 inches**, allowing efficient coverage in a single pass. The machine’s compact **turning radius of 141 inches** enables maneuverability in confined job sites. Powering the DD70 is a reliable **Cummins 4B NA (naturally aspirated) engine**, a 3.9-liter inline four-cylinder diesel engine known for its simplicity, durability, and ease of maintenance. This engine variant typically delivers between 60-100 horsepower, optimized for low-power, continuous-duty applications common in compaction equipment. Its naturally aspirated design ensures straightforward operation without turbocharging, enhancing reliability and fuel efficiency. Overall, the Stone DD70 combines effective vibratory compaction capability with a dependable powertrain and compact dimensions, making it well-suited for infrastructure, road repair, and landscape grading tasks requiring smooth, well-compacted surfaces. The mechanical simplicity of the Cummins 4B engine and the controlled vibration frequency allow for consistent compaction while minimizing operator complexity and downtime.
