Product Description
Built for demanding excavation, grading, and demolition work, this 2021 Sany SY215C delivers 21 tons of proven performance in a site-ready package. Powered by a Mitsubishi 4M50 engine generating 118kW at 2000rpm, this machine combines reliable traditional power with the precision hydraulics needed for deep foundation work, trenching, and material handling across construction and infrastructure projects.
With a maximum digging depth of 6,600mm and a reach extending to 10,280mm, this excavator tackles deep utility installations and wide-radius earthmoving with equal capability. The 1.1m³ backhoe bucket (adjustable 0.8-1.2m³) moves material efficiently, while 138kN bucket digging force and 103kN arm force cut through compacted soil and challenging ground conditions. Operating weight of 21,900kg provides stability during heavy lifting and slope work up to 70% grade.
- Mitsubishi 4M50 water-cooled diesel: 580N.m torque at 1600rpm
- Maximum excavation height: 9,600mm; unloading height: 6,730mm
- 390L fuel capacity for extended shifts without refueling
- Currently located in Maoming, Guangdong—ready for immediate deployment
