Excavators are highly integrated electromechanical hydraulic heavy machinery, and due to their operation in harsh and complex construction environments, their lifespan, performance, and reliability heavily depend on the quality of daily maintenance. For operators and managers, understanding the key points of maintaining the major components of an excavator is fundamental to extending equipment lifespan, reducing malfunctions, and improving efficiency. This article will introduce the daily maintenance methods and precautions for six major components: the engine, hydraulic system, undercarriage (chassis), working mechanism (boom, dipper arm, bucket, pins, etc.), electrical system, and attachments/connecting parts (pins, couplings, quick-change mechanisms, etc.), focusing on their functionality and operability.
