VOLVO DD120B STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD120B static smooth drum roller is a robust compaction machine designed for efficient soil and asphalt compaction. It features a wide 78.7-inch (2000 mm) steel drum providing an operating width of 88.5 inches for effective coverage. The machine has an inside turning radius of 148.5 inches, ensuring maneuverability in confined workspaces. Powered by a Volvo Deutz D4 four-cylinder, water-cooled diesel engine, it delivers reliable performance with a power output of approximately 148 hp (110.4 kW). The engine incorporates advanced direct fuel injection and complies with stringent emission standards, enhancing fuel efficiency and reducing emissions. The roller generates a vibration frequency ranging from 50 to 70 vibrations per minute, producing a centrifugal force of 42.67 kip (189.8 kN) to achieve optimal compaction results. With an operating weight of roughly 12.7 metric tons, the DD120B balances substantial ground pressure for compaction with machine stability. It has transport dimensions of about 19.67 feet in length, 7.38 feet in width, and 10.46 feet in height, facilitating logistical handling. The roller's travel speed reaches 7.08 mph (11.4 km/h), supporting efficient site mobility. Designed for asphalt and soil applications, the DD120B integrates Volvo’s water spray system to prevent asphalt sticking and enhance compaction uniformity. This model is widely recognized for its durability, ease of operation, and maintenance-friendly features suitable for medium to large-scale construction projects requiring consistent compaction performance.
