XN08 log grapple on mini-X

This is my first test of a mechanically-articulated log grapple that came as an accessory to my Chinese XN08 excavator. It replaces the bucket on the dipper and uses mechanical action to close the inboard jaw. The bucket cylinder operates the outboard jaw.

Hows this little machine held up over the years ?

I have the same excavator. How to you get the bottom of the claw to stay attached? When I attach my claw the bottom swings freely. Thank hou.

You have to use both the bucket pivot and the mechanical thumb pivot at the end of the dipper stick. Did your machine come without the mechanical thumb pivot?

@@dfk8881 yes, it did. I didnt easily see a way to attach it. Now I know I need to use it maybe I can try again. Thank you very much.

@@matthewhanson7697 I have experimented with homemade mechanically-articulated grapples before, and this one works in a similar way. But it will not last since some of the pivots are not greaseable. For my XN08, I cut off the factory mechanical thumb pivot and welded a new one on the dipper so I could install a custom hydraulic thumb. The stroke of an hyd cylinder makes it so that you can not use the pivot for the mechanical thumb.

@@dfk8881 your hydraulic thumb i really like. so you made that? it was not factory option correct?

[@dfk8881]

@@DieselRamcharger None of the several Chinese factories that make this excavator offer an hydraulic thumb, AFAIK. All offer the mechanical thumb and the mechanical grapple. I have made hydraulic thumbs from scratch for both my tractor, and this mini-X.
