Friction bolt
The Split Set stabilizer is a slotted steel tube, with one end tapered for easy insertion into a drill hole. The other end has a welded ring flange to hold the bearing plate.
Immediate Support: The anchors provide instant stabilization as they are driven into the rock, creating friction that holds the surrounding material in place.
Efficiency: The straightforward installation process reduces downtime and increases productivity in mining operations. Frictional Resistance: They generate friction along the entire length of the anchor when inserted into a hole, providing immediate support.
