Specification Unit Sakai Drum Roller SV400D | 7.3 ton

The Sakai SV400D is a medium-sized vibratory single-drum roller specifically designed for efficient soil compaction in small to medium-scale earthmoving projects.
It is well-regarded for its high centrifugal force relative to its size and its dual-frequency vibration system.
Below are the key specifications for the SV400D (7.3-ton class):

Weights & Operating Data

Operating Weight (with ROPS): Approx. 7,350 kg (7.35 tons / 16,210 lbs).
Weight on Front (Drum): 3,500 kg (7,720 lbs).
Weight on Rear (Axle): 3,850 kg (8,490 lbs).
Static Linear Pressure: 20.6 kg/cm (115 lbs/in).

Vibratory System

The SV400D features a dual-frequency/dual-amplitude system, allowing the operator to adjust based on the material type.
Frequency: 30 Hz / 38 Hz (1,800 / 2,300 vpm).
Centrifugal Force (Low/High): 93 kN / 118 kN (20,940 / 26,460 lbs).
Nominal Amplitude: 1.40 mm / 0.75 mm.

Engine Specifications

While older units may feature a Cummins or Isuzu engine, newer iterations (like the SV400-2) typically use a Deutz engine.
Engine Model: Deutz TCD2011L04W (or Cummins B3.3T / Isuzu A-4BG1 in some markets).
Type: 4-cycle, water-cooled, direct injection with turbocharger.
Rated Output: 74.9 kW (100 HP) @ 2,300 rpm.
Fuel Tank Capacity: 180 Liters (47.6 gal).

Dimensions & Mobility

Overall Length: 4,900 mm (193 in).
lass=”yoast-text-mark” />>Overall Width: 1,920 mm (76 in).
>Overall Height: 2,815 mm (111 in).
Drum Width: 1,700 mm (67 in).
Drum Diameter: 1,300 mm (51 in).
Ground Clearance: 315 mm (12.5 in).
Travel Speed: 0 – 10 km/h (0 – 6.2 mph).
Max Gradeability: 62% (approx. 32°).

Key Features

Patented Vibration Isolation: Uses a unique rubber isolator system to protect the operator and electrical gauges from heavy vibrations.
Hydrostatic Transmission: Provides variable speed ranges for smooth transitions between working and transit modes.
Dual Independent Braking: Includes a primary hydrostatic brake and a secondary “Spring-Applied, Hydraulically Released” (SAHR) mechanical brake.
