Hyundai HX300 LR is a crawler excavator in the Hyundai Construction Equipment HX series, configured for long reach applications. It is designed for tasks such as dredging, slope finishing, riverbank work, demolition support, and other projects requiring extended digging distance and working depth. The HX300 LR typically uses a diesel engine, hydraulic excavator undercarriage, and a long-reach boom and arm arrangement to increase operating envelope. It is used in construction, civil engineering, and material handling environments where reach is more important than breakout force. Specifications may vary by market, year, and attachment package.
