  • Tool coupler system having multiple pressure sources
    Patent number: 9217235
    Abstract: A tool coupler system is disclosed for use with a machine. The tool coupler system may have a tool coupler with a hydraulic actuator configured to selectively lock a tool to a machine. The tool coupler system may also have a first hydraulic pump configured to generate a first flow of pressurized fluid, and a second hydraulic pump configured to generate a second flow of pressurized fluid. The tool coupler system may further have a valve configured to selectively direct the first or second flows of pressurized fluid to the hydraulic actuator of the tool coupler.
    Type: Grant

  • Tool coupler having anti-release mechanism
    Patent number: 8684623
    Abstract: A tool coupler for a machine is provided herein. In an embodiment, the tool coupler may have a coupler frame, a hook coupled to the coupler frame and configured to receive a first pin of a tool, and a wedge operatively connected to the coupler frame. The tool coupler may also have an actuator connected to move the wedge away from the hook to bias a second pin of the tool against the coupler frame, and a latch associated with the wedge. The latch may be movable between a first position at which the wedge is allowed to move away from the second pin, and a second position at which the wedge is constrained from moving away from the second pin.
