VOLVO DD118HFA STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD118HFA is a high-performance static smooth drum roller designed for efficient soil and asphalt compaction. It features a robust Cummins turbocharged and charge air-cooled engine delivering up to 148 hp, enabling it to handle demanding compaction tasks. The roller’s drum measures 78.7 inches in width and 55.2 inches in diameter, providing broad compaction coverage. It operates at a variable vibration frequency range of 3,000 to 4,200 vibrations per minute (50 to 70 Hz) with a nominal amplitude of 0.1 inches at both high and low settings. This allows adaptability for different material thicknesses and stiffness, optimizing compaction quality and productivity. The DD118HFA generates a centrifugal force up to 42,062 lb at its highest amplitude, ensuring effective compactive effort. Its compact overall width ranges from 6.6 to 7.26 feet with a tight inside turning radius of 12.4 feet, which facilitates maneuverability in confined spaces. Weighing approximately 27,260 lb and carrying a fuel capacity of 53.1 gallons, the machine can operate for extended periods with a maximum travel speed of 6.6 mph. The roller features a drum wetting system with dual water pumps and multiple nozzles to prevent asphalt sticking and maintain a smooth finish. Its overall length is about 19.67 feet with a height to cab top of 10.37 feet and 20.08 inches of ground clearance for stable operation on uneven terrain. Additional Volvo innovations include chamfered drum edges to reduce drum marking and a patented impact meter to optimize rolling speed and drum impact spacing for enhanced efficiency and surface quality.
