The future is open.

Open-S is the open standard for fully automatic quick couplers for excavators. The goal is to give machine operators and contractors around the world the freedom to combine machine couplers, tiltrotators and tools from manufacturers that are in compliance with the standard, and to promote continued technological development.

Open-S builds on the established symmetrical quick coupler standard, the S Standard, and welcomes industry manufacturers to take an active part in this technology agreement.




Now the choice is yours!

With an open standard for quick couplers, machine operators and contractors can more easily choose machine couplers, tiltrotators and tools, and be confident that they will work together.

The standard also means that dealers can provide clearer information about which products fit together.


Choose from different manufacturers

We believe that healthy competition is the best way to promote continuous product development and customer benefits. With a common standard, it’s easier for industry manufacturers to continue to compete with performance and functionality, and still offer customers compatibility.

Open-S opens the door to the future.



Safety first

Reducing the risk of accidents and incidents is a priority and in recent years, major and important advances have been made in terms of product and operator safety. With Open-S, you can be more confident that these solutions will continue to work. The open interface defines hydraulic couplers and ensures that a combination of products from different manufacturers will not in any way interfere with or alter the safety solution of each individual product.
