The Kobelco SK300 LC-11 is a hydraulic excavator in the 30-ton class, designed for general earthmoving, site development, utility work, and material handling. It is part of Kobelco's SK series and uses a long crawler undercarriage for stability and ground contact on uneven terrain. The LC designation indicates a long carriage configuration, which supports balance and digging performance. The SK300 LC-11 is typically equipped with a diesel engine, hydraulic boom and arm system, and a full-rotation upper structure. It is used in construction, excavation, trenching, and loading applications where reach, digging force, and operating stability are required.
