Описание Продукта
Built for serious excavation, the 2020 Hyundai R455LC-7 is a 45-ton workhorse currently located in Zhejiang, China, and ready for immediate deployment. Powered by a Cummins QSM11-C engine producing 263 kW at 1,900 RPM, this machine delivers the raw hydraulic force and reach demanded by large-scale digging, heavy grading, and structural demolition projects.
With a bucket digging force of 256 kN, a maximum digging depth of 7,790 mm, and a 2.15 m³ backhoe bucket, this excavator moves serious material on every pass. Dual variable axial piston pumps supply 2 × 380 L/min, keeping hydraulic response sharp across all work circuits.
