Steelwrist’s new SQ quick coupler is the ‘biggest’

The SQ90 quick coupler with hydraulic hammer attachment

Designed for use with excavators weighing from 40 to 70 tonnes, the SQ90 incorporates Steelwrist’s QPlus technology, which 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 of shaft of the machine, which is said to “significantly” limit the risks associated with unintentional attachment drops.

According to Steelwrist, it developed the model in response to a growing global demand for fully automatic coupler systems in the construction and demilotion sectors.

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

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.
