SuperGrip-R

SuperGrip-R

The SuperGrip-R is a brushwood grapple. It’s based on the same frame as the rest of the SuperGrip series, but has heavily reinforced brushwood arms specially designed for forwarding brushwood, forest residue, and tree residue – even stumps.

The arms have no knives but extra reinforcement to handle the most demanding forwarding. Under the boom line is a sturdy reinforcement plate connecting the shanks to prevent them from getting bent out of shape.

Lift only what you want to lift

Anyone who’s tried to harvest brushwood with a regular log grapple knows why you need a special brushwood grapple. There are no knives at the grapple opening, just four reinforced arms. The result is that the brushwood is squeezed together and the grapple no longer jams when opened. Most of all, you lift only what you want, without any debris that makes the forest residue difficult to sell.

Designed to work under pressure

Just like the SuperGrip std and the SuperGrip-S, the SuperGrip-R has a cylinder that can handle up to 250 bar. High-strength plate is used throughout, and it features Hultdins’ classic expander pin system to eliminate play.
