Tata Hitachi Zaxis 80
Pros
- 7 m reach and ~8.2 m cutting height help with truck loading and general excavation.
- Counted as a mid‑size excavator, it’s stable yet not too heavy for site access.
- Suitable for attachments like breakers, grapples, and augers with decent auxiliary flow (~178.5 L/min referenced).
LiuGong 921 Di
Pros
- Offers respectable digging depth (~5.9 m) and horizontal reach (~9.2 m), making it suitable for medium‑sized construction and earthmoving tasks like trenching, foundation work, and site prep.
- The boom and reach balance enables both digging and loading without needing heavy long‑reach modifications.
- Compared with heavier or lighter models, the 921Di’s boom reach fits well in the 20‑22 t excavator segment
