The Open-S Alliance welcomes four new members to the organization, all well-known companies within machine distribution and excavator attachments industry: Earth Machine Co., Ltd. and Tokumitsu Machinery Co., Ltd. (Japan), and GP Equipment and Niroc Machinebouw B.V. (the Netherlands). With the growing global demand for fully automatic couplers, the initiative to create an open standard, launched in 2020, continues to grow in importance and attract new members.

The basic idea with the Open-S standard is to create a global open standard for automatic couplers. With a standardized hydraulic interface it is possible to combine attachments from different brands, connecting them safely and reliably, avoiding proprietary solutions that locks the customer into a specific system. The customers can select the solution that best solves their individual needs, and that supports flexible use of machines and attachments.

Open-S Alliance is happy to present the latest new members:
