SANY SY120C-9
Pros
- Cummins ~100.5 hp engine delivers solid output for its class with good torque and fuel economy
- Hydraulic system tuned for responsive and smooth combined operations.
- Reinforced structural components like anti‑wear bucket plates and quality components improve service life.
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
