Overview

Quick answerHydraulic quick hitch for 1–40 t excavators with check valve and safety lock. Q345B + NM400, custom pin sizes 20–110 mm, CE & ISO.

Our hydraulic quick coupler lets the operator release and pick up buckets and attachments from the cab in seconds. A pilot-operated check valve holds the cylinder under load and a mechanical safety pin provides a second lock, so the attachment stays secure even if a hose fails.

Frequently asked questions

Does it come with the solenoid and switch kit?

Yes, a complete kit with solenoid valve, in-cab switch, buzzer and hoses is included.

Can it carry a breaker?

Yes, as long as the breaker bracket uses the same pin sizes; we can make breaker brackets to match.

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.
