Compact mechanical coupler for micro excavators. Simple hex-key operation allows for quick and easy attachment swaps.
Safety is not optional. Our MS System hydraulic couplers feature active locking systems and check valves to ensure your attachment stays exactly where it belongs.
Hydraulic pressure actively holds the wedge in the locked position, ensuring a tight connection at all times.
Integrated check valves maintain cylinder pressure even if a hose bursts, keeping the attachment secure.
A clear visual indicator allows the operator to verify from the cab that the coupler is fully locked and safe to use.
