Experience Maximum Safety, Productivity and Versatility With Our Fully Automated Digger Couplers

For decades Miller has been committed to product innovation, listening to customers to design and develop automated digger couplers that are best in class. Our fully automated quick couplers are seen as game-changers in the construction industry, effectively increasing the safety and speed of attachment changes whilst maximising the versatility of an excavator.

Every aspect of the Miller GT Series is manufactured with superior performance in mind. From our innovative casting process to our strict R&D tests that employ over 100K cycles of extreme fatigue testing with heavy-duty stress gauges, we ensure that each device is powerful enough to withstand even the most demanding conditions.

A Lightweight, Lower Profile Design For Optimal Onsite Efficiency

Our unique iron casting process utilises a blended design approach, eliminating the risk of weak points that often come with welded couplers to offer an extremely robust and safe solution.

Advanced digger couplers from Miller are fully cast using heat-treated high-grade steel to guarantee strength and longevity while remaining lightweight. We’ve developed a lighter, low offset design for our intuitive digger couplers that reduces the engine load to improve the stability and fuel efficiency of your machine. A shorter pin to point measurement also empowers maximum breakout force to drive productivity during jobs.

Intelligent Quick Couplers For Diggers That Allow High-Speed Attachments

Our unrivalled range of couplers for diggers are expertly manufactured to facilitate quick, secure attachment changes to ensure your operations run as smoothly and safely as possible.

Where manual couplers can only deliver 5-minute attachment changes, our Miller GT Series completes changes in 18 seconds, allowing minimal downtime on jobs and maximum tool versatility.

Compatible with compact excavators from 1 to 6 tonnes, the Miller GTS coupler boasts a cutting-edge design with reduced internal components to keep repair and maintenance costs down. Manufactured with the same matchless design expertise, our GTX quick coupler offers the safest, lightest, lowest yet strongest solution in the marketplace for excavators of 8 to 50 tonnes.

The universal variable pin centre of the Miller GTS and GTX Series couplers allows a full array of OEM attachments to be picked up and swapped by operators from the comfort and safety of their cab to boost machine productivity.

The award-winning Miller Powerlatch Quick Coupler features our ISO1301 compliant twin locking system that guarantees the safest attachments for excavators from 3.5 to 120 tonnes. Our patented Automatic Blocking System safeguards against accidental attachment failure and dropped buckets with a reliable independent back up system, to maximise the safety of your fleet.

Delivering a 180-degree tilt for 3.5 to 20-tonne excavators, the Miller Powerlatch Tilt offers powerful endurance and converts all buckets into rotating buckets without having to reposition the excavator or manually change attachments, for a time-saving, flexible solution that makes grading and demolition simple.
