HS quick coupler system

These are the HS 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.

4 sizes, our attachments for 0.6 - 15 t machines.

We make brackets for this system only. The coupler itself comes from its maker.

HS is a symmetrical quick coupler interface. The size number sets the pin spacing, so a bracket built for one HS size belongs to that size only.

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.
