Caterpillar 320D vs Komatsu PC200-8
The 20-ton class represents the absolute backbone of global construction. The Caterpillar 320D and Komatsu PC200-8 are undisputed legends in this tier. Let's compare them across core metrics.
1. Engine & Power Comparison
Both models feature exceptionally robust engines engineered for heavy construction duty:
- Caterpillar 320D: Powered by the Cat C6.4 ACERT engine delivering 110 kW (148 HP). Known for immense torque, superior digging force in hard rock, and outstanding durability, though fuel consumption is slightly higher under full load.
- Komatsu PC200-8: Powered by the Komatsu SAA6D107E-1 engine (110 kW / 148 HP). Exceptionally smooth power delivery, quieter idle, and famous for balanced fuel economy under standard digging modes.
2. Hydraulics & Control Response
Hydraulic flow control determines the excavator's actual speed on site:
- CAT 320D: Employs high-pressure pilot-operated hydraulics. Delivers rapid joystick response and extreme breakout forces. The choice for heavy quarry and tough demolition.
- Komatsu PC200-8: Employs Komatsu's patented HydrauMind closed-center system. Incredible coordination, offering unmatched precision and fine grading control for urban landscaping and trenching.
3. Technical Specs Comparison Matrix
| Metric / Feature | Caterpillar 320D | Komatsu PC200-8 |
|---|---|---|
| Engine Model | Cat C6.4 ACERT | Komatsu SAA6D107E-1 |
| Digging Breakout Force | 140.1 kN (Very High) | 138 kN (High) |
| Fuel Economy Index | ★★★★☆ | ★★★★★ |
| Aftermarket Spare Parts | Abundant Worldwide | Abundant Worldwide |
Importers seeking maximum heavy-digging breakout force should choose the Caterpillar 320D; those prioritizing precision grading, lower noise, and premium fuel efficiency should go with the Komatsu PC200-8.
