Larger excavators can now benefit from increased versatility for demolition work with the new unit from Steelwrist

The firm claims that the addition of the SQ90 coupler meets the demand from the demolition industry, where many and fast work tool changes are common. The SQ units allow operators and machines to work continuously and the new model now allows larger excavators to offer increased versatility.

SQ90 as well as all other Steelwrist SQ products follow 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, while allowing the units to function together.

The front pin lock is a mechanical lock of the front shaft which limits the risk of an unintended drop of work tools. The patented front pin lock technology has also been upgraded to a second generation to cope with heavy demolition work tools as well as the tough working applications.

All SQ couplers come with QPlus technology which is said to allow high hydraulic flows with less pressure drops.
