POWERTILT MECHANICAL PIN GRAB COUPLER The AMI Axxis PowerTilt Mechanical Pin Grab Coupler offers the same features as a standard AMI coupler, but with the additional versatility of 180 degrees rotation on 25-70 series excavators and 120-degrees on 130-400 series excavators. Ideal for sloped trenching, excavating around foundations and sidewalks, as well as ditch cleaning, the Axxis PowerTilt Mechanical Pin Grab Coupler requires one set of bi-directional auxiliary hydraulics to operate the tilt function and also requires a Coupler Control Kit for the Hydraulic Pin Grab.
