Excavator is an engine driven construction machinery equipment used for excavating materials such as soil and rocks. The common working scenarios of excavators include excavating and moving earthworks, rock formations, crushing hard rocks, coal mines, sandy soil, waste residue, and soil piles. Excavators are usually composed of components such as boom, boom cylinder, boom cylinder guide valve, boom cylinder rod sleeve, boom cylinder liner, boom cylinder rod, boom cylinder liner, boom specific valve group, wire rope, and boom mechanism. Excavators are mainly operated by bucket car mechanisms to carry out excavation, loading, transportation, and other tasks. The main working principle of excavators is to achieve excavation and loading work through the drive of the engine, using the boom and trolley mechanism. The engine transmits power to the boom and trolley mechanism through the transmission system, and the trolley can rotate when necessary to achieve operations in all directions. Excavators have the characteristics of high operating efficiency, wide operating range, good flexibility, and strong adaptability. It has a wide range of applications in civil engineering, mining, agriculture, municipal engineering and other fields, and has become one of the indispensable equipment in modern engineering construction.
