Anchors and Rock Bolts - OMEGA-BOLT® Expandable Friction Bolt
The main application of the OMEGA-BOLT® Expandable Friction Bolt is temporary rock reinforcement in Mining and Tunneling. Bonding forces between the friction bolt and the rock mass are caused by form closure and friction transfer between the borehole wall and the rock bolt which is expanded by hydraulic pressure.
Main Advantages
- Immediate full load bearing capacity over the entire installed bolt length
- Low sensitivity against vibrations caused by blasting works
- Ability to maintain load-bearing capacity even when undergoing deformations
- Safe and easy installation
- No additional building materials required for installation
- Flexibility in case of differing or varying borehole diameters
- Quality check during every single installation
- Different customized high-pressure pumps available
