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
SANY SY140C-9S
Pros
- The 3.9 L Cummins diesel is known for good fuel use and reliability in medium machines.
- The SY140C-9S comes in tunnel (compact) and quarry (full boom) variants — great adaptability to confined or open environments.
- Uses 2 variable-displacement axial piston pumps and remote monitoring, improving digging and cycle performance.
