STONE DD90 STATIC SMOOTH DRUM ROLLER

Technical Description

The STONE DD90 Static Smooth Drum Roller is engineered for high-efficiency compaction in road construction and large paving projects. It features dual smooth drums, each with a width of 66 inches, enabling an operating width of 75.2 inches for effective surface coverage. The roller’s inside turning radius is 140 inches, providing maneuverability on job sites. Equipped with a robust Cummins QSB 4.5L Tier 3 engine, this model delivers between 109 to 170 horsepower, optimizing power and fuel efficiency while meeting emission standards. The drum vibration frequency operates at 41.7 vibrations per minute, enhancing compaction quality through controlled dynamic forces. The machine’s static weight contributes significantly to its compaction ability, complemented by the vibration system for improved soil or asphalt density. Designed with a focus on operator visibility and control, the DD90 supports productivity and operator safety. Its durable construction includes machined drum surfaces with chamfered edges for consistent contact and smooth performance. The hydrostatic drum drive system provides reliable traction and speed control, capable of speeds up to approximately 7.9 mph, with a theoretical gradeability of 26%. Overall, the STONE DD90 balances power, precision, and durability for demanding compaction tasks, making it suitable for highway, airport, and heavy construction applications. The Cummins engine technology ensures efficient operation with electronic fuel management and turbocharged air-air intercooling for improved power delivery and reduced emissions. This smooth drum roller is optimized for professional contractors requiring consistent, high-quality compaction performance.
