The Hyundai HX300 LR is a large excavator designed for long-reach applications in construction, demolition, dredging, and material handling. It is part of Hyundai's HX series and is configured with an extended boom and arm for increased working reach and digging depth. The HX300 LR is typically used where standard excavators cannot access distant or deep work areas. It features a diesel engine, hydraulic system, enclosed cab, and undercarriage built for heavy-duty operation. Common uses include riverbank work, slope finishing, and site clearing. Specifications may vary by market, attachment, and production year.
