Steelwrist’s new SQ fully automatic quick coupler is its ‘biggest’

The new SQ90 incorporates Steelwrist’s QPlus technology for higher hydraulic flows “with less pressure drops than many other systems on the market”

Steelwrist’s new SQ90 quick coupler is designed to meet a growing demand for fully automatic coupler systems in construction and demolition. The SQ90 is the biggest model in the company’s SQ Auto Connection product range so far.

Designed for use with excavators weighing from 40 to 70 tonnes, the SQ90 incorporates Steelwrist’s QPlus technology for higher hydraulic flows “with less pressure drops than many other systems on the market,” and its upgraded Front Pin Lock safety feature.

The second generation of the manufacturer’s patented Front Pin Lock system was developed specifically to support heavy demolition attachments. It does this by mechanically locking the front shaft of the machine, which is said to “significantly” limit the risks associated with unintentional attachment drops.

“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,” said Stefan Stockhaus, CEO of Steelwrist. “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.”

The SQ90 joins the SQ60, SQ65, SQ70, SQ70/55 and SQ80 quick coupler models as part of the Auto Connect Range, which was first launched in 2017 and is fully compliant with the Open-S standard.

Open-S is the open standard for fully automatic quick couplers for excavators. It stems from a joint initiative between Rototilt and Steelwrist aimed at giving machine operators and contractors the freedom to combine machine couplers, tiltrotators and tools from manufacturers that are in compliance with the standard, and to promote continued technological development.

Open-S builds on the established symmetrical quick coupler standard, the S Standard, and welcomes industry manufacturers to take an active part in this technology agreement.
