BOBCAT E50z
Pros
- Powerful Engine for Class: ~49 HP diesel offers strong performance for a 5-ton mini.
- Good Digging Depth & Reach: ~3.55 m dig depth and ~5.92 m reach help versatile site work.
- Compact Zero-Tail Design: Excellent maneuverability in tight spaces and urban sites.
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
