Truly the leader in hydraulic wedge couplers, AMI offers the most innovative design features including compact size (even on full-size excavators) and an exclusive mechanical safety lock like nothing else ever invented. The wedge coupler system gives you the full power of your excavator without sacrificing break-out force. The unique bucket lugging keeps the pin-to-tip radius exactly to factory specification. The Power Wedge Coupler is the fastest and easiest way to switch attachments. A spring-loaded safety pin instantly locks the wedge and is visible from the cab so you know it's locked. The hydraulic release feature also allows the operator to release the safety lock without leaving the cab. The low profile design keeps the pins low, meaning you don't have to sacrifice breakout force.
