Quick Couplers - Technical Data

             The precision fastening between Quick Coupler and attachment ensures optimum wear protection.
             The wear-resistant materials also guarantee maximum durability.

            The Dedicated System from Martin ensures maximum use of the clearance on the excavator (dimension R).
            The overall height is reduced as the  bucket saddle is optimised for mounting the Quick Coupler. Once the bucket is mounted,
            the Quick Coupler is integrated in the saddle of the bucket. Wear between the excavator bucket and Quick Coupler is reduced
            to a minimum.
