Friction Stabilizer Bolt

Friction stabilizer bolt is a new type anchor of full-length anchoring and active reinforc-ement of surrounding rock.
It is composed of anchor rod and tray. The anchor rod is made of high-strength steel pipe and has longitudinal slits. When it is installed in a borehole slightly smaller than the pipe diameter, it can immediately apply radial pressure to the borehole through entire length and prevent the surrounding rock from sliding down. Coupled with the supporting force of tray, the surrounding rock is in a three-direction stress state to achieve rock stability.
The bolt is mainly used in hard rock mines, tunnels or emergency rescue, which can quickly provide supporting force to achieve better supporting effects.

  • Features and Advantages

    The installation is simple and can be completed only by impact;

    No anchoring agent required;

    The friction between anchor rod and rock is large;

    High shear and tensile strength;

    Equipped with a high-strength tray, the tray is evenly stressed;

    Support can be provided timely in radial and axial directions.
