  • Tool coupling arrangement having zero offset
    Patent number: 11208785
    Abstract: A tool coupler for coupling a tool to an end of a machine link. The tool coupler having a coupler frame, a hook configured to receive a first pin of the tool and configured to attach to the end of the machine link such that the tool coupler, a wedge slidingly received within the coupler frame, and an actuator connected to the wedge to move the wedge away from the hook to bias a second pin of the tool against the coupler frame. The tool coupler mounts the tool to the machine link such that the tool and the tool coupler pivots about the same axis.
