وصف المنتج
Built for operators who demand precision and control, this 2021 Hyundai R505LVS delivers 50-ton performance with exceptional stability across demanding job sites. Powered by a Cummins QSM11 engine producing 299 kW at 1800 rpm, this excavator combines raw power with refined hydraulics—dual variable plunger pumps supply 2 x 405 L/min for responsive bucket and boom control. The spacious cabin offers commanding visibility across an 11,050 mm maximum digging radius, while the water-cooled turbo-charged engine ensures consistent performance during extended shifts.
- Operating weight: 50,200 kg with 2.8 m³ bucket capacity
- Superior reach: 6,900 mm maximum digging depth, 10,280 mm digging height
- Proven Cummins power: 10.8 L displacement, 6-cylinder configuration
- 9 rpm rotation speed with axial piston motor and automatic braking
- 70% climbing ability and dual-speed travel (5.1/3.25 km/h)
- 620 L fuel capacity for extended operation
- Currently located in Fujian, China—ready for global deployment
