[0002] Excavator connectors refer to the parts that connect the various working devices of the excavator, including the dipper arm, bucket ears, bucket teeth, etc. These connectors play the role of connecting, fixing and transmitting force, so that the excavator can effectively complete various work tasks. The design and manufacturing quality of the connectors directly affect the working performance and safety of the excavator. Usually, the excavator connectors are made of high-quality alloy steel materials with high strength, wear resistance and deformation resistance to cope with the use environment under various harsh working conditions. In addition, the installation and maintenance of the connectors are also crucial. Correct installation can ensure the stability and reliability of the connectors, while regular maintenance can extend the service life of the connectors, reduce the equipment failure rate, and improve the working efficiency and economy of the excavator.
