Steelwrist has introduced the SQ90, the largest model in its ‘SQ’ ‘Auto Connection’ quick coupler range for excavators up to 70t specifically involved in demolition activities.

After the SQ quick coupler launch in 2017, the range today consists of the SQ60, SQ65, SQ70, SQ70/55 and SQ80 being now followed by the introduction of the SQ90. SQ couplers aim to provide increased safety and provide the ability to change hydraulic powered work tools in seconds without leaving the cab. The addition of the SQ90 coupler meets demand from the demolition industry, where many fast work tool changes are common. “The Steelwrist SQ Auto Connection quick couplers have been appreciated by the customers from day one. In the demolition industry, with its frequent work tool changes, it is all about using the right tool for the right job at the right time. SQ allows operator and machine to work continuously at all times and work safety increases when operators can easily change and use the best tool for the job,” says Stefan Stockhaus Steelwrist AB CEO.

SQ90, as well as all other Steelwrist SQ products, follows the global Open-S industry standard for fully automatic couplers for excavators. The standard makes it easier for machine operators and contractors to choose quick couplers, tiltrotators and work tools from different manufacturers and be confident that they function together. Furthermore, all SQ couplers come with ‘QPlus’ technology which enables higher hydraulic flows with less pressure drops than many other systems on the market.

The SQ90 also benefits from Steelwrist’s ‘Front Pin Lock’ which is a mechanical lock of the front shaft which significantly limits the risk of an unintended drop of work tools. The patented technology has been upgraded to a second generation in order to support heavy demolition work tools.
