Werk Brau Co. Inc., a Findlay, Ohio-based manufacturer of heavy equipment attachments, has announced it has joined the Open S Alliance, a Sweden-based group formed to encourage a common standard for automatic couplers for excavator attachments.

Why it matters

The Open S Alliance aims to bring clarity, safety, and true compatibility to the attachment marketplace by supporting an open, global standard for fully automatic quick couplers. This empowers operators, dealers, rental houses, and contractors to work more freely without the limitations of proprietary systems.

The details

As part of the alliance, Werk Brau says it can help ensure the 'attachments operators rely on every day remain compatible, reliable and ready for whatever the job demands.' Excavators equipped with Open S-compliant couplers can interchange attachments from multiple manufacturers, which Werk Brau says helps improve jobsite efficiency, reduce downtime and expand equipment capability.

  • Werk Brau has manufactured attachments for more than 75 years.
  • The Open S Alliance was formed earlier this decade.
