DESCRIPTION

Descriptions:
The shaft of the Friction Stabilizer consists of a metal strip which is folded to form a slotted tube. The bolt is installed into a borehole by applying impact energy. The borehole features a slightly smaller diameter than the outer diameter of the bolt tube. The principle of this anchor system is based on the bond between the borehole and the tubular bolt shaft, caused by applying a force onto the borehole wall, which generates a frictional resistance in axial direction.

Key Features:

One of the most popular solution for hard rock mining

Superior performance thanks to axial and radial expansion forces

Extensive testings, ductility and traceability of the raw materials

Ring: quality of welding and proven performance

Main Benefits:

Easy to handle

Easy to install

Black/ Hot dip galvanisation available

Wide range of lengths
