The Friction Anchors can be installed with either hand held or mechanised equipment (Jumbos, Roof bolters, etc.) to provide an immediate frictional rock support at the face. For additional corrosion protection, Friction Anchors can be galvanised or thermally zinc diffused with a Distek™ coating.
Our Friction Anchors are made from high tensile steel, roll formed into open slotted tubes. Driving the high tensile steel tube into a hole with diameter smaller than the tube diameter generates a radial force on the rock. This results in a frictional resistance to the pull-out of the tube from the hole. A steel ring is fixed to the collar end of the tube to retain a bearing plate (washer).
Advantages of the Product:
- Immediate support.
- Fast and easy installation.
- A full length support.
- It remains effective at any angle of installation.
- Cost effective.
- Batch identification is added to inner side of the tube.
- Visual inspection is simple.
- It is an ideal means to retain Welded Mesh.
- Rock movement improves its effectiveness as a support medium.
- May be used in conjunction with Combo Plate, W-Plate, W-Strap or Osro Strap to increase areal coverage
