Quick Couplers / S60 Quick Coupler
S60 Quick Coupler
Symmetrical quick coupler for excavators in the 12-18 ton range.
Steelwrist quick couplers are designed around three leading principles Robust, Compact and Safe. The Quick Coupler is a wedge type coupler following the Symmetrical Standard and is fully compliant with ISO13031 (Earth-moving machinery – Quick Couplers – Safety).
Thanks to the combination of casted components and truss structure design we have achieved a relatively low weight yet a very robust design. With the casted front hubs, which allows for oversized pin contact surfaces, we distribute the digging forces into the coupler structure like no other brand on the market.
The Steelwrist coupler is also the only coupler on the market that uses the shafts as part of the truss structure in order to take up side forces incurred when working with a tiltrotator.
With only 135mm of building height on the S60 quick coupler the difference between a direct fit tiltrotator and a sandwich construction tiltrotator is minimal. We recommend that for wheeled excavators from 14 tons and upward to use a coupler together with your tiltrotator.
The Symmetrical Coupler Standard is by itself a very safe system compared to some other of the European type couplers. By using a Symmetrical Coupler you will fulfill basic requirements like:
- It is only possible to use bucket following the same standard. (With an S60 coupler you can only pick up a work tool that has a S60 adaptor. It is not possible to pick up a bucket that is not designed to fit your coupler)
- Wedge type locking, whereby the angle of the locking wedge is in cooperation with friction which counteracts the tendency to disengage.
- No digging forces into the locking cylinder even under reverse digging (dig away from driver)
On top of these features the Steelwrist Quick Couplers have continuous locking force, check valve and internal springs for safety back up items.
