Stone Grab/ Scrap Gab SG52HD
This grapple has a two prong jaw on one side, and a single
jaw on the other. The jaws and the wear parts are made out of Hardox steel.
Besides lifting stones, this grapple can also be used for
the handling of logs. The form of the jaws is such that the grab also penetrates
into piles of brush or logging slash.
