ABSTRACT:
The invention provides a coupling assembly and method for coupling a tool to a dipperstick, or arm, on an apparatus which has a hydraulic system for moving the tool. The coupling assembly includes a coupler body having link structure for pivotally coupling to the dipperstick. A latch member is movable between an engaged position for engaging the tool and a disengaged position for disengaging from the tool. A spring is arranged to provide a spring force to urge the latch member to the engaged position. A hydraulic motor has a part that is stationary relative to the coupler body and a movable part that can be extended relative to the stationary part when hydraulic pressure is applied to one end of the hydraulic motor. The movable part is coupled to the latch member such that extension of the movable part urges the latch member to the retracted position in opposition to the spring force.
