CAT 320D
Pros
- Proven Cat C6.4 ACERT engine with solid torque and power for mid‑size excavator tasks (earthmoving, trenching, loading).
- 5.7 m boom and ~9+ m digging height help in both shallow and medium depth work.
- Caterpillar’s dealer network is extensive — spare parts availability is usually strong globally.
SANY SY35U
Pros
- At ~3.8 t operating weight, it strikes a balance between power and maneuverability for urban/medium jobs.
- Makes working in tight spaces easier — minimizes side‑overhang when swinging.
- Powered by a Yanmar 3TNV88F (~18.2 kW / ~24–28 hp) with efficient load‑sensing hydraulics.
