| Engineering Parameter | Certified Specification Range | Field Operational Context |
| Operating Weight | 20,000 kg – 22,000 kg (~44,000 – 48,500 lbs) | Massive static weight concentrated primarily over the front steel drum for maximum deep compaction. |
| Weight on Drum | 13,000 kg – 14,500 kg | High static linear load ensures immediate density progression in the initial passes. |
| Drum Width | 2,130 mm – 2,200 mm (84 to 86 inches) | High-capacity heavy drum width built to maximize square-meter coverage per shift. |
| Drum Type | Smooth Drum or Padfoot (Sheepsfoot) | Smooth: Best for gravel, sand, and rock-fill.
Padfoot: Interlocking feet designed to break down and compact heavy clay and cohesive soils. |
| Vibration Frequency | 28 Hz – 34 Hz (1,680 – 2,040 vpm) | Dual-frequency system optimized for shifting and settling deep, coarse grain materials. |
| Nominal Amplitude | High: 1.8 mm – 2.1 mm
Low: 0.9 mm – 1.2 mm |
High Amplitude: Destined for thick lifts / deep soil beds.
Low Amplitude: Used for thin finish layers or sensitive structures. |
| Centrifugal Force | 360 kN – 420 kN (High Amplitude) | Massive impact force created by eccentric weights to eliminate deep-seated air voids. |
| Engine Net Power | 190 HP – 230 HP (140 kW – 170 kW) | High-torque, turbocharged diesel engine (e.g., Cummins, Cat, or Deutz) built to maintain power on steep grade inclines. |
Roller Compactor
XS203J road roller
A 20-ton single drum vibratory soil compactor is a heavy-duty production machine engineered for large-scale earthworks. It is the industry standard for stabilizing deep lifts of cohesive or granular soils, gravel bases, and rock-fill materials on massive infrastructure projects like highways, airport runways, dam construction, and industrial foundations
