Specification Unit Sakai Drum Roller SV526DF | 11.9 ton

The Sakai SV526DF is a 12-ton class vibratory single-drum roller designed for medium to heavy soil compaction. The “DF” designation typically refers to the Combi Drum (or padfoot-shell compatible) configuration, which provides high versatility across different soil types.
Below are the technical specifications for the Sakai SV526DF:

Key Features

Versatility: The DF model is often equipped with a drum shell that allows it to handle both smooth and cohesive soil tasks effectively.
Durability: Features Sakai’s original shock-absorbing system to prolong the life of the drum and operator deck.
Maintenance: Simple design with fewer electronic components for easier field repairs.
Would you like me to compare these specs with the standard smooth drum (SV526D) or the padfoot (SV526T) models?
