Frequently asked questions

How long does a change take?

Typically 2–5 minutes, including fitting the safety pin.

Can I upgrade to hydraulic later?

We offer hydraulic versions with the same pin dimensions.

Hydraulic or mechanical quick coupler – which should I buy?

Hydraulic couplers are operated from the cab and are fastest for frequent changes. Mechanical couplers use a manual screw or spring lock, need no extra hydraulic line and cost less – ideal for occasional changes.

Will your coupler fit my excavator?

We make couplers to your pin diameter, pin-to-pin distance and arm width. Send these measurements (or the excavator model) and we will produce matching drawings before production.
