CAT 321
Pros
- 136 HP Cat C3.6 engine delivers strong digging performance.
- An advanced electrohydraulic system improves cycle time.
- Eco Mode and Intelligent ECM help reduce fuel consumption
SANY SY220C-9
Pros
- A ~7 m reach allows efficient loading of small to medium trucks and bins, and good coverage for trenching and grading tasks within the segment.
- Boom geometry is well‑suited for tight spaces, making the SY80C‑9 popular for urban excavation, roadside work, and utility trenching
- The machine intelligently matches hydraulic flow with the boom/arm work profile, improving fuel efficiency during digging and lifting.
