Product Description
Commanding a 21-ton workhorse from Hunan, operators benefit from the R215VSN's precision-engineered control systems and robust hydraulic architecture. Built with a Cummins QSB7 engine delivering 125kW at 1900rpm, this excavator combines reliable power with responsive handling across demanding jobsites. The dual variable plunger pumps supply 2×222 L/min flow, ensuring smooth simultaneous operations while maintaining exceptional bucket and boom control.
Operator-centric design features include:
- Enhanced visibility with 2970mm transport height and optimized cabin positioning
- Stable platform supported by 19,900kg working weight and 2830mm rear turning radius
- Precise maneuverability with 11.4rpm rotation speed and two-speed travel system (5.9/3.8 km/h)
- Confident grading capability on slopes up to 70% with axial piston hydraulic motors
- Extended reach of 9720mm maximum digging radius with 6550mm depth capacity
Water-cooled 6-cylinder configuration maintains consistent performance during extended shifts, while the 0.83m³ backhoe bucket handles substantial material volumes. Hydraulic responsiveness and mechanical stability make this joint venture model a dependable choic
