Specification Unit Sakai Drum Roller SV400TB2 | 8 ton

The Sakai SV400TB-2 is an 8-ton class vibratory single-drum roller designed for small to medium earthmoving projects.
The “TB” designation indicates it is equipped with a traction-assisting dozer blade, making it versatile for both backfilling and high-performance soil compaction.
Below are the detailed technical specifications for this unit:

Weights & Dimensions

The SV400TB-2 is slightly heavier and longer than the standard smooth-drum version due to the addition of the dozer blade.
Feature Specification;
Operating Weight 8,050 kg (approx. 17,745 lbs).
Load on Front (Drum) 4,380 kg.
Load on Rear (Axle) 3,670 kg.
Overall Length 5,330 mm (210 in).
Overall Width 2,250 mm (89 in).
Rolling Width 1,700 mm (67 in).
Wheelbase 2,650 mm (104 in).
Drum Diameter 1,300 mm (51 in).

Engine & Performance

Powered by a reliable Deutz engine, this model is built for fuel efficiency and climbing power.
Engine Model: Deutz TCD2011 L04W.
Type: Water-cooled, 4-cycle, 4-cylinder with Turbocharger.
Rated Output: 74.9 kW (100 HP) @ 2,200 rpm.
Travel Speed: 0 – 10 km/h (6.2 mph).
Gradeability: Approx. 50% (26°) — Note: Gradeability can vary based on ground conditions.

Vibratory System

The SV400 series features a dual-frequency system to handle various soil types, from granular to semi-cohesive materials.
Vibration Frequency: 38 Hz (Low) / 30 Hz (High).
Centrifugal Force: 127 kN (approx.10 28,550 lbs).
Amplitude: 1.52 mm (0.060 in).
Vibrator Type: Eccentric shaft type.

Key Features & Safety

Three Braking Systems: Includes a hydrostatic dynamic brake (via F-N-R lever), a spring-applied hydraulically released (SAHR) park brake, and a standard emergency foot pedal.
Operator Comfort: Features Sakai’s patented vibration isolation system, which protects the operator deck and instruments from the intense vibration forces.
Traction: The TB model includes a strike-off (dozer) blade used for leveling surfaces and light backfilling, ensuring the drum doesn’t “bridge” over high spots.
Serviceability: Fully opening engine hood for easy access to hydraulic components and filters.
Would you like me to find a comparison between this model and its padfoot (SV400TF) or standard smooth-drum (SV400D) counterparts?
