Standard
CW CW-System compatible quick-couplers
The whole range: Excavator quick couplers
- up to 60 tons
Quick-couplers compatible with CW system brackets, in manual, fully automatic and tilt/swivel versions. The wedge design keeps breakout force high, and a pilot operated check valve secures the attachment hydraulically; a lifting hook is available as an option.
About this family
On the hydraulic versions the check valve keeps the wedge locked if hydraulic pressure drops, so the attachment cannot come loose. The range covers CW-00 for carriers under 1 t through CW-45 for 25–45 t machines, with the shorter "S" variants beside each size and hydraulic tilt/swivel CW-U models over the whole span. CW is the coupler interface used in the Netherlands and Belgium. Every dimension, carrier class and mass below is printed in the Quick-Coupler-Systems catalogue.

Which coupler is on your machine?
Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.
Safety
- Loss of hydraulic pressure
- A pilot operated check valve works as a further hydraulic lock on the coupler.
