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 SY20C
Pros
- Small size and lightweight (~1.8 t) make it ideal for urban sites, landscaping, utilities, and confined spaces.
- Expandable undercarriage options (on some versions) increase stability on uneven ground.
- Load-sensing hydraulic system improves responsiveness and controllability relative to basic minis.
