galvanized split sets for mine support

Introduction of underground mining rock anchor bolt split set anchor The Split Set 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.The stabilizer is inserted into a hole slightly smaller in diameter than the tube, using a simple driver tool fitted to the drill.As the tube enters, its diameter is compressed and the slot partially closes. This exerts radial forces along the length of contact with the rock, providing the friction which holds the rock together. The driving force of the drill actively loads the bearing plate against the rock splite set Mining and Ground Support: Split Set friction rock stabilizers are used for underground or surface support in many applications: Places Where Need Ground Support Split Set Rock stabilizers are an easy solution to your ground support, mine roof support and other stabilizjuing, holding, or anchoring problems.
