Applications for excavator quick connectors and subdivision fas

  • Quick Coupler, also known as an excavator rapid connector. Among these, the  tilting quick coupler can rotate roughly 180 degrees, allowing the operator to more precisely position the attachments without having to reposition the machine. This increases overall productivity and adaptability.


    Excavator quick replacement joints allow for the quick installation of various configuration accessories on the excavator, such as a bucket, soil loosening device, crushing hammer, hydraulic shear, wood grabber, stone grabber, and so on, which can broaden the excavator's scope of application, save time, and improve work efficiency.


    Classification of excavator quick connectors

    Excavator fast connectors are classified as mechanical or hydraulic.



    A brief overview of the excavator quick linker

    High strength materials are used; Korea utilizes 20M high strength board, whereas China utilizes Q345B board.

    Suitable for all tonnages ranging from 4 to 50 tons.

    To assure safety, a liquid control check valve safety mechanism is used.

    Excavator configuration parts do not need to be reconnected, and the pin shaft may be replaced without having to remove it, so installation is quick and can considerably enhance work productivity.

    The hydraulic type rapid changing joint's operation principle

    The oil cylinder acts primarily to fix and release the hydraulic quick change joint on pin shafts 1 and 2. When it is time to replace the functioning parts, the oil cylinder is retracted and the hook press block is moved from position 1 to position 2. The fast change joint is removed and replaced with other operating parts. The oil cylinder is opened again once the hook press block has been aligned with the pin shaft, and the hook press block moves from position 2 to position 1, and the pin shaft of the working parts is locked. Of course, the external oil and solenoid valve are both active at the same time.


    The mechanical rapid changing joint's operation principle

    Domestic mechanical quick joint manufacturers' products are primarily classified into two types: bolt type and screw type.

    When replacing parts on a bolt type, for example, first remove the wedge card, which will knock down the inside of the T buckle (T buckle can be smoothly the red part press block to recycle, here in the face of the welding requirement is higher, slide rail welding not level off, at the same time polishing not clean, red briquetting action hard to smooth.) The quick connector has been removed from the bucket. When the required working part is replaced, the T-buckle is retracted and the wedge card is fitted into the T-buckle for locking.
