VOLVO DD31HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD31HF Static Smooth Drum Roller features a hydrostatic propulsion system that drives both drums, ensuring maximum gradeability and efficient compaction performance. It has an operating weight of 6,840 lbs with ROPS, making it sturdy yet maneuverable for mid-size compaction tasks. The roller is powered by a Kubota engine delivering 49.2 hp, providing reliable and consistent power for various soil and asphalt applications. Its drum measures 49.2 inches wide with an operating width of 53.7 inches, facilitating broad coverage with each pass. The machine's vibration system operates at a frequency of 70 Hz (4200 vibrations per minute) with an amplitude of 0.015 inches, effectively compacting materials through high-frequency vibratory force. The overall dimensions include a length of 101 inches, width of 53.7 inches (4.5 ft), and height of 99.5 inches, offering a compact footprint suitable for urban and confined job sites. The combination of smooth drum design, hydrostatic drive, and high vibration frequency makes the DD31HF ideal for asphalt and granular base compaction, ensuring uniform surface density and durability in road construction and maintenance projects.
