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.
Tata Hitachi Zaxis 23 U
Pros
- Zero Tail Swing: The rear of the machine stays within the track width, making it perfect for working next to walls or in narrow lanes.
- Versatility: Equipped with a boom swing feature, allowing you to dig offset to the machine's path (useful for digging foundations along walls).
- Ease of Transport: At roughly 2.3 tons, it can be easily transported on a standard small truck or trailer.
