Flexibolt Anchor

Flexibolt

The Flexibolt cable anchor was designed and developed in 1993 by Dr. Peter Fuller and Dr. Paul O'Grady (Senior Rock Engineers from the Coalfields in Australia) and subsequently patented worldwide. Duraset has secured the exclusive rights for the Flexibolt in South Africa and SADC.

The Flexibolt originated from the need for a flexible anchor system that does not require hydraulic equipment to tension.  To satisfy this need, the Flexibolt is tensioned by hand or a rockbolter and has the capability of being re-tensioned.  Pre tension loads of 2-5 tonne can be achieved. The revolution of this new design was first presented at the 12th International Conference on Ground Control in Mining at Morgantown West Virginia, USA, 1993.
