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 SY20U
Pros
- Zero-tail swing design makes it ideal for tight, confined job sites such as urban construction, landscaping, housing sites, and utilities work.
- Load-sensing hydraulics deliver smooth flow and good fuel use for a mini excavator of this size.
- • Works well for small earthmoving, trenching, irrigation, and utility trench jobs where a bigger excavator isn’t practical.
