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 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.
