SV400T Sakai SV400T Specifications & Technical Data (2018—2026)

Braking Systems

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.

Engine and Hydraulic Components

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. The hydraulic system includes conveniently located pressure gauge ports. Large ball bearing and taper bearings are employed in the center-pin mechanism to prolong service life and lubrication intervals. The vibrator bearing lubrication system keeps lubricating bearings even during hillside operation.

Selected quality components provide outstanding reliability under harshest conditions.

Well-balanced front and rear weight distribution contributes to excellent traction and slope climbing ability. Three basic drum types are available; smooth drum, padfoot drum and smooth-to-padfoot quick-change combination drum. An optimal selection of drum type and setting of dual-frequency dual-amplitude vibration system allows the SV400 roller to handle different types of material efficiently under a wide variety of working conditions. The hydrostatic transmission offers variable speed ranges and an ideal speed is easily selected for either working or transit.

Vibration Isolation System

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. All control and instruments are ergonomically arranged in order to reduce operator fatigue. A cushioned, adjustable bucket seat with arm rests is standard.
