The Sakai GW750 is a unique “Vibratory Pneumatic Tire Roller.”1 Although it has an operating weight of approximately 9 tons, it is designed to achieve the compaction results of a 25-ton static tire roller by combining traditional kneading action with high-frequency vibration.
Below are the detailed technical specifications for the GW750 and the updated GW750-2 models.

Weight & Dimensions

Specification Metric Units Imperial Units:
Operating Weight (with ROPS) 9,240 – 9,280 kg 20,370 – 20,460 lbs.
Max. Operating Weight 9,100 kg 20,062 lbs.
Overall Length 4,540 mm 179 in.
Overall Width 2,200 mm 87 in.
Wheelbase 3,000 mm 118 in.
Compaction Width 1,950 mm 77 in.
Ground Clearance 265 mm 10 in.

Engine & Performance

Engine Options:
Tier 2: Isuzu DD-4BG1T (78.8 kW / 106 HP).
Tier 3: Isuzu 4JJ1XDIA (92.0 kW / 123 HP).
Speed Range: 0 – 12 km/h (3 speeds available).
Gradeability: 38% (21 circ).
Vibration Frequency: 40 Hz (2,400 VPM).
Centrifugal Force: 4-stage adjustable, ranging from 8 kN to 58 kN. (approx.4 1,765 to 13,140 lbs) per axle.
Amplitude: 4 settings (0.10 mm to 0.74 mm).

Tire & Steering System

Number of Tires: 7 tires total (3 Front / 4 Rear).
Tire Size: 14/70-20-12PR (Smooth tread).
Steering Type: Articulated (Center-pin).
Turning Radius: 5.4 m (Outer) / 3.8 m (Inner).
All-Wheel Drive: Standard, to prevent “shoving” or pushing of Hot Mix Asphalt (HMA).

Fluid Capacities

Fuel Tank: 130 Liters (34.3 gal).
Hydraulic Tank: 65 Liters (17.2 gal).
Water Sprinkler Tank: 600 Liters (158 gal) — usually two 300L tanks.

Key Features

Dynamic Kneading Action: Unlike standard rollers, this model vibrates the pneumatic tires, allowing a 9-ton machine to compact thick layers (up to 25 cm) that usually require a 25-ton machine.
Dual Spray System: Equipped with both water and release agent pressurized spray systems to prevent asphalt from sticking to the tires.
Versatility: Ideal for thin HMA overlays, aggregate bases, and roller-compacted concrete (RCC).
