S-System quick coupler system

These are the S-System sizes our model tables print. Open a size to see the attachment models that list it. The bracket for your machine is confirmed with your quote.

8 sizes, our attachments for 0.6 - 65 t machines.

We make a quick coupler for this system.

S is the Swedish quick coupler standard. The size number sets the pin diameter and the pin spacing, so the size decides the bracket, not the make of the machine.

The quick coupler we make for this system: QC-S - S-System Scandinavian quick-coupler.

Every quick coupler is tested before dispatch.

  2. Measure the distance between the pin centres.
  3. Measure the width between the inside faces of the ears.
