CAT 320D3
Pros
- Strong engine performance for a 20-ton class excavator: 134 HP gross (100 kW), ~114 HP net. Great for heavy digging and lifting tasks.
- Typically well-insulated, ergonomically arranged operator cab with adjustable suspension seat, good visibility, and modern controls.
- Selectable power modes (Power, Smart, Eco) improve fuel efficiency depending on task.
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.
