SANY SY375EP
Pros
- Strong engine with ample torque for deep digging and heavy earthwork – ~212 kW (~284 HP) from 7.8 L engine is solid for 37-ton class.
- High breakout & crowd forces – SY375H variant has ~235 kN bucket force and ~210 kN arm force, meaning strong material penetration
- Robust for heavy excavation / quarrying / mining use – Designed as a “large” excavator with stronger components and durable build.
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
