JCB NXT 145 QUARRY MASTER
Pros
- Heavy‑duty boom & reinforced structure designed for quarry and mining conditions
- Boom/arm regenerative system improves hydraulic speed and lowers fuel use.
- IP67/IP69 electrical connectors, laminated cabin glass, advanced safety features.
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
