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.

Coupler Lift HookCenter-mount heavy duty lift hook comes standard.
Datum BarsThree sturdy datum bars connect the two halves of the coupler, providing strength to the weldment for a reliable, flex-free coupler frame.
Electric Switch BoxA tamper-proof self contained switch box is provided with the coupler installation kit. This is mounted in the cab and has a locking rocker switch as well as a buzzer and a light to indicate and remind the operator the coupler is in the unlocked position.
Fast ChangeoutCoupler design allows an experienced operator to safely change attachments on the fly in under five seconds.
Hydraulic Diverter ValveThe diverter valve provided with the coupler installation kit diverts pressure from the bucket cylinder to the ACS coupler locking cylinder when the control switch is activated. The valve also contains a rectifier circuit that diverts pressure to the coupler locking cylinder when the bucket moves in any direction. This keeps the coupler cylinder always pushing in the locked position.
Visual ConfirmationThe patented ACS Excavator Coupler locks by rotating the locking mechanism around the front bucket pin. The operator can visually confirm the coupler is locked in place.
Combination CouplerYou can order your coupler to be configured to pick up attachments made for different models. This is useful if you purchase a new excavator of a different brand and want to keep all of the existing attachments for the old machine. Equipping the new machine with the Combo Coupler would allow it to use the existing attachments without having to revise the ear-group for the new machine. This saves the cost of reworking the existing attachments. Combo Couplers can only be considered for exchanging attachments between similar size machines.
