II. Operating principle

Anchoring principle of the bolt with plastic expansion case is to cause a radial force by means of action of initial bolt plastic expansion case and the angular surface of cone, friction shall happen so that to achieve anchoring effect. Then pull the plastic cone move axially through the final anchor to strengthen the action force between plastic expansion case and rock hole wall. The required anchoring strength shall then be achieved.

Product performance:1. Test anchoring strength >=50KN (meet the standard of MT146.1-2002) .
