JCB 520X LC
Pros
- Powerful 400 HP engine delivers excellent performance.
- Operating weight of up to 55,300 kg ensures high stability.
- Large bucket options up to 3.4 m³ support high-volume material.
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
