POWER SET Self-Drilling Friction Bolt

The POWER SET Friction Bolt is a selfdrilling reinforcement element used for ground control in Mining and Tunneling. In addition, the POWER SET rock bolt system is deployed for rock fall and rock slide protection.

This patented one-step POWER SET rock bolt system stands for a safe and easy installation as well as immediate load-bearing capacity after installation. Another feature is the flexibility of the POWER SET Self-Drilling in regard to changing rock conditions.

Optional installation of an expansion element features additional mechanical anchorage up to the ultimate load of the friction bolt tube. A specially developed automation unit for six bolts per installation sequence allows safe and state-of-the-art rock bolt installation.
