SG36-HD Grapple
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. The wear plates and the sturdy jaws enable the
grapple also be used in the handling of building debris. The
design of the grapple makes it an all-around utility grapple.
