en.Wedoany.com Reported - American attachment manufacturer Werk-Brau has announced its membership in the Open-S Alliance, becoming the 25th member of the organization. Werk-Brau officially supports the global Open-S standard for excavator automatic quick couplers, which aims to achieve interchangeability and compatibility between attachments from different manufacturers.
Headquartered in Findlay, Ohio, Werk-Brau was founded in 1947, starting as a small blacksmith shop. After four generations of family operation, it has developed into a global manufacturer of attachments for excavators, mini excavators, skid steers, and wheel loaders. Its product range covers buckets, thumbs, quick couplers, and more.
The Open-S Alliance was co-founded in 2020 by Swedish automatic coupler manufacturers Rototilt and Steelwrist. The Open-S standard is built upon the symmetrical S standard and extends into the field of fully hydraulic quick couplers. This enables excavators equipped with compliant couplers to freely interchange attachments, tilt rotators, and working tools from different manufacturers. The alliance's website states: "Freedom of choice helps create better conditions for innovation and sustainable development. Closed systems create lock-in effects, limiting users' ability to choose the best products."

Trevor Ballinger, Vice President of Werk-Brau, said: "By supporting the Open-S standard, we are helping to create a future where operators have greater flexibility, enhanced compatibility, and more control over how they work. This is about doing the right thing for our customers and the industry." Stefan Stockhaus, Chairman of the Open-S Alliance Board, welcomed the Werk-Brau brand to the alliance, noting that the initiative to create open industry standards is gaining support in North America.
Automatic quick coupler systems allow excavator operators to quickly change attachments without leaving the cab, with hydraulic hoses connecting simultaneously. This enables a single machine to efficiently use multiple attachments on the same job site. The Open-S standard also supports the use of tilt rotators, which allow for rotation and tilting of attachments, improving operational precision and productivity.
Following Werk-Brau's membership, Open-S Alliance members in North America include Wisconsin-based attachment manufacturer Genesis, Connecticut-based distributor A&D Equipment, and Seattle-based Pacific JCB dealer. Other members also include Epiroc, Indeco, Volvo Construction Equipment, and Wacker Neuson.
