"Fast connector" is a term for a wide range of industrial products and is divided into hydraulic pipe quick connectors and excavator quick connectors. This refers to excavator quick connectors (also called quick-change joints, quick connectors). The quick connector can quickly install various configurations (dippers, ripper, breakers, hydraulic shears, etc.) on the excavator and can be expanded. The use of excavators can significantly save time and improve work efficiency.
