Product Description
Commanding a 21-ton workhorse from Jiangxi, operators benefit from the precision-engineered control systems that define the 2017 R215VSN. Built with joint venture quality standards, this excavator delivers 125kW of Cummins QSB7 power through a dual variable plunger pump system, providing responsive hydraulic flow of 2×222 L/min for smooth, predictable movements across all functions. The spacious cabin offers exceptional sightlines to the 9,720mm maximum digging radius and 6,550mm depth capability, while the two-speed axial plunger travel motors with integrated parking brake ensure confident positioning on grades up to 70%.
- Enhanced stability: 19,900kg working weight with optimized 2,830mm rear turning radius
- Superior visibility: Elevated operator position with clear views to 0.83m³ backhoe bucket
- Precise handling: Axial piston swing motor with automatic braking for controlled rotation at 11.4 rpm
- Operator comfort: Reduced vibration from water-cooled 6-cylinder engine and pilot-operated controls
- Confident travel: Dual-speed capability (5.9/3.8 km/h) with robust 46-plate track system per side
Designed for demanding applications where operator efficiency directly impacts
