Product Description
Commanding a 21-ton workhorse from Luzhou, Sichuan, this 2020 Hyundai R215VS delivers precision control and operational confidence for demanding excavation tasks. Powered by a robust Cummins QSB7 engine generating 125 kW at 1900 rpm, operators benefit from responsive hydraulic performance through dual variable plunger pumps flowing 2 x 222 l/min. The spacious cabin provides exceptional visibility across a 9930mm maximum digging radius, while intuitive controls manage the 0.92m³ backhoe bucket with surgical accuracy.
- Enhanced stability: 20,900 kg working weight with optimized counterweight design
- Superior reach: 5650mm boom and 2920mm arm configuration for versatile positioning
- Smooth operation: Two-speed axial plunger travel motors with automatic braking systems
- Operator comfort: Water-cooled cabin environment with 360-degree sightlines
- Proven reliability: Joint venture manufacturing with imported Cummins power plant
With 70% climbing ability and 11.4 rpm rotation speed, operators maintain productivity on challenging terrain while dual-speed travel (5.6/3.7 km/h) ensures efficient site navigation. Comprehensive hydraulic systems and 340L fuel capacity support
