  • Coupler for coupling attachments to excavation machines
    Patent number: 9670642
    Abstract: A quick coupler for coupling an attachment, such as a digging bucket, to an evacuator machine. The quick coupler includes a first fixed jaw for a first coupling pin of the attachment. The quick coupler includes a latch cooperating with the first fixed jaw, which is moveable to a latched position for retaining the first coupling pin. A moveable jaw is provided that is able to slide, under power of a hydraulic ram, to a closed position retaining the second coupling pin. A locking arm assumes a locked position, while the latch assumes the latched position, preventing withdrawal of the moveable jaw from the closed position. Consequently, in the event of a hydraulic failure the locking arm simultaneously locks both the first attachment coupling pin, by means of the latch, and the second attachment coupling pin by means of preventing movement of the movable jaw from the closed position.
