Tata Hitachi EX 70 Super Plus
Pros
- Good power for size: 55 HP is respectable for a 7‑ton class — strong for medium earthmoving.
- Decent boom height & reach: ~7.5 m cutting height gives flexibility in loading trucks/stockpiles
- Relatively simple to operate & maintain: Tata Hitachi’s wide dealer network in India
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.
