Komatsu PC5500-6
Pros
- Very large bucket capacity (~29 m³) for fast loading and high material movement.
- Two powerful engines provide high output suited for heavy mining operations.
- Available in both backhoe and shovel configurations to suit different mining tasks.
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
