Our high quality British made buckets are expertly designed to improve your excavator's digging efficiency.

Powerlatch Quick Coupler

Maximum safety, strength and performance.

Our award-winning quick coupler transforms excavators into multi-tooled carriers.


We’ve continually evolved our quick coupler design to excel through the changing needs of the construction industry and new legislation. Our PowerLatch Coupler is the best yet, surpassing everything else in safety, strength and longevity.

Our patented and exclusive Automatic Blocking System (ABS) prevents the accidental release of an attachment. In the unlikely event of a hydraulic failure or driver error, buckets cannot be dropped or swing dangerously on the front pin.


Cast from high tensile steel, it’s light and exceptionally strong. We removed surplus weight from non-load bearing areas and reduced the top section of the coupler for a more compact, aesthetic product. Wear indicators also make the couplers easier to service than ever before.

So if you want to decrease you overall payload and maximise your machines efficiency, use less fuel and boost your bottom line — speak to a member of the Miller team today.


Global Industry Compliance

  • Meets all relevant Global legislation, including EN474, Machinery Directive 2006/42/EC, AS4772, NSW Workpaper and ISO 13031

  • The PowerLatch ‘twinlocking’ coupler will only allow the release of attachments in a safe, curled position.

  • In the event of hydraulic failure or accidently operating the switch, the PowerLatch will automatically lock on both front and rear pins, mechanically and independently.

  • Ensures the attachment remains securely engaged complying with all current and future global legislation

Universal Connectivity

  • Turn your excavator from a digging machine to a  multi-tooled carrier ideal for performing versatile functions.

  • Eliminate extra equipment on your jobsite as variable pin centre design allows you to easily pick up and swap the widest range of OEM attachments.

  • The Miller PowerLatch coupler allows you to change attachments quickly from the comfort and security of your cab.

  • Maximising machine productivity with less down time.

  • Effectively it locks both front and rear pins which prevents buckets or attachments to swing on the front pin only.

Maximise Breakout Force

  • Innovative fully cast low profile design.

  • Low profile design delivering a shorter pin to point measurement which delivers maximum breakout force for greater productivity.

  • Achieving the perfect machine balance of versatility and optimised breakout force.
