SuperGrip II-R

SuperGrip II-R

As part of the SuperGrip II series, the SuperGrip II-R was launched at the start of the new millennium. We took the basic characteristics of the successful SuperGrip – the geometry, the gripping force, the expander pins – and modernized the design.

As demand for bioenergy gradually grows, so do the requirements for grapples for harvesting forest residue. The SuperGrip II-R is a good example of this development.

Designed specially for forest residue

The characteristics of the SuperGrip II-R are, essentially, the same as the rest of the SuperGrip II series, although we’ve developed this model with a special focus on forwarding brushwood and tree residue. So the SuperGrip II-R is a somewhat lighter brushwood grapple. Its predecessor, the SuperGrip R, has heavier reinforcements under the boom line and is a more suitable choice for handling stumps.

Same strong components

Just like the other grapples in the SuperGrip II series, the R-model has both a frame and arms of high-strength robot-welded metal plate, a solid cast metal brace with steel bushings, and a powerful cylinder able to handle up to 250 bar. Need we mention that the pins are of the expander type?
