A coupler (31) for coupling implements having a first connecting pin and a second connecting pin, to a vehicle, for example, to the arm of an excavator. The coupler has a body component (33) that is connectable to the vehicle, and which includes a forward recess (37) for receiving the first connecting pin. A forward locking member (91) is provided for securing the first connecting pin within the forward recess. The coupler also includes a movable component which is supported by the body component and which has an aft jaw or recess (41) for receiving the second connecting pin and is movable through a range of travel relative to the body component. The movable component includes a rear locking member (51) which is movable between an extended position in which the rear locking member can prevent the second connecting pin from exiting the aft recess and a retracted position in which the rear locking member can allow the second connecting pin to exit the aft recess. A rear locking actuator is provided for moving the rear locking member between its extended and retracted positions. A method of disengaging a work attachment or implement from a coupler is also disclosed. The forward locking member is supported by a hydraulic manifold, which supplies fluid to the locking member through the pivoted connection between the two. |
