CAT 320C
Pros
- Smooth & Powerful Performance
- Reliable & Durable
- Comfortable Operator Environment
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.
