you'd have to have an extremly well made mechanism, linkages and not to mention a really good actuator to get good forces in a horizontal crusher.

my new ones just about met its match at 15mm hdpe, it'll crush it but only so far in before it stops. something which the old horizontal pinsor never could have managed, that wouldn't have even gone through 5mm or so

jamie, i'd really suggest that you used the 800kg actuator on a vertical claw like mine cos youd get crazy power in that. but then the draw back is how yours is and how mine used to be it was easy as hell to drive up to a robot and grab hold of it, going to be difficult getting a robot to stay in my claw whilst it closes with both of us probabily moving about n that
