Outstanding compactive effort in thick layer compaction
Hourly work volume is the greatest in its class due to its heavy operating weight and the highest amplitude. The SV900 enables compaction in layer thickness of 60 - 90 cm (2 -3 ft.) in each lift and efficiently achieves the required density.
Wide variation of drum types
Smooth drum or padfoot drum, with standard vibration mode (single eccentric type) or vertical vibration mode (twin eccentric type-V type) are options available to select from
• Standard vibration models : SV900D (smooth drum), SV900T (padfoot drum)
*Single eccentric in a drum, conventional type
• Vertical vibration models (V type) : SV900DV (smooth drum), SV900TV (padfoot drum)
*Two(2) eccentrics in a drum only generate vibration force in the vertical direction and forces in all othe directions are cancelled out (eliminated). Thus, it is more effective for thick layer compaction.
High Safety Standard
• The SV900's are equipped with three brake systems ;
Hydrostatic dynamic brake is applied when forward-reverse lever is in neutral
Parking brake engaged by push switch on dash
Emergency brake pedal (exclusive feature of SAKAI rollers)
Emergency brake is automatically applied if engine or hydraulic failure occurs
• Ecellent all-around visibility, complies with European visibility criteria of 1m × 1m (one by one)
