SANY SY150C PRO
Pros
- Competitive power (~100.5 HP) and productivity for ~15 ton segment.
- PRO series typically uses modern variable‑displacement pumps with good control for bucket, boom, and travel functions.
- 0.76 m³ bucket suitable for general excavation & utility 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
