A&D Equipment, Nishio Rent All, and Zijtveld Grijpers join the Open-S Alliance, strengthening the initiative to create an open industry standard for automatic couplers for excavators. New members from North America, Asia, and Europe demonstrate the idea of an open standard to gain ground globally as more and more manufacturers share the value of offering contractors with products following a standardized interface. With the addition of these three companies, the Open-S Alliance now has 20 members.

A&D Equipment, Inc., based in Guilford, Connecticut, serves the construction industry with excavator attachments, tiltrotators, and work tools. The company is committed to continually researching and testing excavation and demolition attachments while offering contractors with innovative products designed to enhance material recycling, excavator performance, and operator efficiency.

Joining the Open-S community presents an exciting opportunity for dealers and buyers alike”, says Donna J. LaFata, president, A&D Equipment Inc.

The Open-S organization welcomes its first member from Japan with Nishio Rent All’s inclusion.

Since the 1990s, it has engaged in the rental of Information and Communication Technology (ICT) enabled construction machinery to improve productivity and quality in the industry. The company also developed ICT systems, taking an advanced and comprehensive approach to supporting contractors.

“In Japan, improving productivity in the construction industry is an urgent issue due to the declining working population and shortage of skilled technicians. As a solution, the Japanese government is promoting ICT and digital transformation, and the use of tiltrotators is one such initiative. The key to maximizing the capabilities of tiltrotators is in the standardization of attachments. As a rental company, we are committed to promoting the Open-S standardization and contributing to the efficiency of the construction industry in Japan and around the world”, says Takashi Kitayama, managing director and general manager of Nishio Rent All Co., Ltd.

Open-S Alliance ​

Open-S is an initiative created in 2020 by industry leaders Steelwrist and Rototilt, with the purpose of developing a global standard for automatic couplers. The objective is to give machine owners and contractors the freedom to combine couplers, tiltrotators, and work tools for excavators from different manufacturers, following the Open-S standard. With an open standard, the utilization increases and profitability improves on all types of job sites, as work tools can be shared easily between different excavators. During the past year, the interest in joining the alliance has increased significantly, with members joining from all parts of the world.

“I am happy to welcome these companies as Open-S members, including our very first member in Japan. We passed an important milestone as the alliance now has 20 member companies from all over the world, all committed to building a standard for automatic couplers. I meet more and more manufacturers that see the value of offering customers products that enhance efficiency and safety on the jobsite without locking them into a proprietary solution”, says Stefan Stockhaus, Chairman of the Board of the Open-S Alliance.
