Excavator Couplers - ACS


Change out attachments in seconds with a coupler that’s built to last and carries the best safety record in the market.

The ACS Hydraulic Excavator Coupler is rugged and compact, delivering the lowest tip radius in the industry. The patented pin-lock design keeps working forces on the frame of the coupler, not the actuating cylinder.

The coupler locks around the pin facing the cab of the excavator, giving the operator visual confirmation that the attachment is safely locked on to the coupler. As a further safety measure, there is a pilot-operated check valve to keep the coupler locked in the event of a hydraulic or electric failure. This is a dedicated “pin grabber” coupler that will be compatible to all attachments with a specific rib group.
