Open-S Alliance has welcomed excavator attachments manufacturer MHA Construction Equipment (China) and earthmoving attachments manufacturer Norm Engineering Pty Ltd (Australia) as its latest members.
The two companies are the first representatives from their respective countries to join the independent organization.
The Open-S initiative was founded in 2020 by 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 that follow the Open-S standard.
MHA Construction Equipment is manufacturer of excavator attachments for demolition, recycling and material handling applications.
Based in Changzhou, it designs and manufactures pulverisers, shears and grapples with strong emphasis on interface compatibility and reliable fitment across different excavator platforms, supporting professional applications worldwide.
“Standardization plays a key role in improving safety, efficiency and interoperability in demolition and recycling, and Open-S provides a strong platform for industry-wide collaboration,” said Mark Kang, marketing general manager, MHA Construction Equipment.
Established in 1984, Norm Engineering Pty Ltd in Brisbane designs and manufactures earthmoving attachments for mini loaders, skid steers, track loaders, excavators, backhoes, telehandlers and tractors for the harsh conditions of Australia.
Since 2019, it has been the sole dealer of Rototilt equipment in the country.
“Norm Engineering has joined the Open-S Alliance allowing us to further enhance our attachment offerings around the globe,” commented director John Pesch.
