CAT 320D
Pros
- Proven Cat C6.4 ACERT engine with solid torque and power for mid‑size excavator tasks (earthmoving, trenching, loading).
- 5.7 m boom and ~9+ m digging height help in both shallow and medium depth work.
- Caterpillar’s dealer network is extensive — spare parts availability is usually strong globally.
Komatsu PC2000-8
Pros
- Huge Power & Digging Performance — ~976 HP engine with a 30 L displacement offers tremendous digging force for mining and massive earthmoving tasks.
- Massive Bucket & Reach — ~12–13.7 m³ bucket capacity and ~15.3 m reach handle large volumes per cycle.
- Heavy Operating Weight (~200 t) for stability and high production work.
