Epiroc (Sweden), Genesis Attachments (U.S.), and Kanamoto Co. Ltd. (Japan) have officially joined the Open-S Alliance. The Open-S industry standard for automatic couplers continues to gain supporters for its standardized coupler interface for the construction and demolition industry. With the standardization, excavators can use work tools from any brand. The result is a more efficient and flexible use of machines and attachments. During 2025 the Open-S Alliance has grown significantly with nine new companies joining the organization and now has 23 members globally.
New members bring expanded options for attachment interchangeability
The three new members are equipment manufacturers Epiroc and Genesis Attachments, and Kanamoto, a large equipment rental company that offers solutions for the construction and civil engineering industries.
Epiroc
Epiroc’s hydraulic attachment tools business segment develops, manufactures, and markets excavator attachments such as breakers, cutters, drum cutters, grapples, or pulverizers for applications in construction, deconstruction, utilities, civil engineering, waste management, mining, or quarrying.
“By joining the Open-S Alliance, we reinforce our commitment to delivering open, compatible solutions that empower customer freedom of choice. This shared standard is not just about technology — it’s about building a more efficient, connected, and sustainable industry,” says Predrag Petrovic, vice president business line hydraulic attachment tools at Epiroc.
Genesis Attachments
Genesis Attachments, an NPK Company, designs and manufactures hydraulic mobile shears, grapples, concrete processors, and specialty attachments for the scrap processing, demolition, material handling, and offshore decommissioning industries.
“The standards set forth by Open-S are a foundation to maintain the best interests of the owners and operators, which perfectly coincide with Genesis’ focus. The information shared through Open-S will ensure that Genesis can continue to offer advanced attachment solutions that seamlessly integrate with supplementary equipment in the field”, says Roger Johnson, director of engineering.
Kanamoto
Kanamoto Co., Ltd. operates a business centered on the rental of construction equipment and owns approximately 810,000 rental assets across about 1,100 equipment types. Through its construction equipment rental business, the company is actively promoting the adoption of Open-S standard attachments, contributing to their expansion not only in Japan but also across Southeast Asia and the Oceania region. Kanamoto welcomes the broader use of various attachments compatible with the Open-S standard.
“Kanamoto places great importance on improving the compatibility of hydraulic excavator attachments used at construction sites. By joining the Open-S Alliance, we expect to create an environment where attachments can be used regardless of model or manufacturer, thereby enhancing user convenience.”
“We also believe that the use of common standards will contribute to greater operational efficiency as a rental company. While incorporating feedback from job sites, Kanamoto will continue to collaborate with other members of the Open-S Alliance to develop innovative attachments that enhance productivity and safety on construction sites”, says Jun Watanabe, member of board of directors and division manager, Construction Equipment Rental Division, Kanamoto Co., Ltd.
“We are thrilled to welcome Epiroc and Genesis — both well-known brands and benchmarks for quality — as members of the organization and supporters of our vision for an open industry standard. It is a true pleasure and an honour to welcome them on board, and I’m convinced their participation will help propel the next phase of our growth. With Kanamoto, the Open-S Alliance welcomes yet another member in Japan, a testament to the international expansion of our ambition to create a global standard. The new members further underscores the momentum behind Open-S and emphasize the importance of interoperability and customer choice”, says Stefan Stockhaus, chairman of the board of the Open-S Alliance.
