Specification Unit Sakai Drum Roller SV520DF | 12 ton

The Sakai SV520DF is a 12-ton class vibratory single-drum roller specifically designed for heavy-duty soil compaction.
It is known for its “DF” (Double Force/Dual Frequency) configuration, often featuring a padfoot drum (or sheep’s foot) or a combi-type setup for deep-lift compaction in cohesive soils.
Below are the detailed technical specifications for the Sakai SV520DF:
