Product Description
Commanding a 50-ton workhorse demands precision and confidence. This 2021 Hyundai R505LVS excavator delivers both through superior operator-focused engineering. Powered by a robust Cummins QSM11 engine generating 299 kW at 1800 rpm, the machine combines raw power with refined control systems designed for extended shifts on demanding jobsites.
Operator advantages include:
- Enhanced visibility across an 11,050 mm maximum digging radius with optimized cabin positioning
- Responsive dual variable plunger pumps (2 x 405 L/min) ensuring smooth, predictable hydraulic response
- Stable platform with 3,780 mm rear turning radius and 1,275 mm counterweight clearance for confined site maneuverability
- Intuitive pilot control system reducing fatigue during precision work
- Impressive 70% climbing ability and dual-speed travel (5.1/3.25 km/h) for versatile terrain navigation
Located in Hangzhou, Zhejiang, this joint venture-manufactured excavator represents proven reliability for heavy earthmoving operations. With 6,900 mm maximum digging depth and 2.8 m³ bucket capacity, operators can maintain productivity while experiencing reduced physical strain through advanced ergonomic design
