SV512D/T/TF

Features

Excellent performance

•	Well-balanced front and rear weight distribution contributes to excellent traction and slope climbing ability.
•	The amplitude of the largest in the world class carries out greatest compaction.
•	The hydrostatic transmission offers variable speed ranges and an ideal speed is easily selected for either working or transit.

Easy operation and riding comfort

•	Despite powerful vibration, the chassis and operator are fully protected from vibration thanks to SAKAI's patented, unique vibration isolation system.
•	Due to the rubber isolator mounted operator deck, the operator's riding comfort is excellent, and electrical instruments and gauges are free from vibration.
•	The vibration ON-OFF switch located on the forward-reverse lever facilitates timely vibration control.

High Safety Standard

•

The roller is equipped with dual independent braking systems. The primary brake is hydrostatic and applied through putting the forward-reverse lever in its "NEUTRAL" position. The three-way secondary braking system is a mechanical spring-applied, hydraulically released type (SAHR) that can be operated either through a push button or pedal or automatically through engine or hydraulic system failure.

•

The overall machine design provides the operator with excellent all-around visibility. (1m × 1m)

Excellent serviceability

•	The engine and hydraulic components are enclosed in a compartment. The engine hood opens fully for easy access to engine and hydraulic components for service and maintenance.
•	Large ball bearing and taper bearings are employed in the centerpin mechanism to prolong service life and lubrication intervals.
•	The vibrator bearing lubrication system keeps lubricating bearings even during hillside operation.
