Product Description
Built for heavy-duty excavation and grading, this 2016 Sumitomo SH210-6 delivers 21 tons of proven performance on demanding job sites. Powered by a reliable engine generating 117.3 kW at 1800 rpm, this crawler excavator handles deep foundation work, mass excavation, and material loading with precision and efficiency.
Equipped with a 0.85-1.0 m³ backhoe bucket, 5700mm boom, and adjustable arm configurations (2900mm/2400mm), this machine achieves a maximum digging depth of 6650mm and an impressive reach of 9900mm. The robust hydraulic system operates at 34.3 MPa, providing 142 kN bucket digging force and 103 kN arm digging force—ideal for breaking through compacted soil and demolition applications.
Key Performance Specifications:
- Operating weight: 21,000 kg with 600mm track plates for stable ground contact
- 410L fuel capacity supports extended shifts without refueling interruptions
- 70% grading capability and 11.5 rpm swing speed maximize productivity
- Compact 2750mm rear turning radius enables work in confined spaces
- Currently located in Wenzhou, Zhejiang—ready for immediate deployment
