CAT 345 GC
Pros
- Designed as the GC (“General Construction”) variant with efficiency focus vs heavier models like 345C or 349.
- Good reach and depth for large trenching, earthmoving and general excavation work.
- 630 L/min flow supports heavy implement movement and attachments smoothly.
Tata Hitachi NX 80
Pros
- Good balance of power (~49 hp) and weight (~7.5 t) for urban and utility work.
- Decent bucket capacity (~0.35 m³) and reach for landscaping, digging, desilting and utility tasks.
- Intelligent hydraulic system with auto idle/auto decel features improves fuel efficiency and reduces cost.
