The Council of Northern Caving Clubs in 1989 in conjunction with DMM the anchor manufacturer, and Hilti the resin manufacturer originally researched the information contained in this document. Permanent fixed anchors continue to be researched and tested by the Council of Northern Caving Clubs through the C.N.C.C. Technical Group. The basic method of installation has not changed. But, over the years, as more has been learnt about how anchors perform in both normal and abnormal use, it has been necessary to make small, but important changes to the method of installation. As these changes are made an updated copy of the installation guide lines, training, testing and documentation will be sent to all the regional anchor re-placement co-ordinators, it is their responsibility to inform ALL the trained installers within their area of the current amendments. In 1994 the National Caving Association initiated the N.C.A. anchor re-placement program and subsequently adopted all the installation and recording procedures that the Council of Northern Caving Clubs had initiated. Anchor re-placement is now co-ordinated on a national basis, but run through the designated person responsible for anchor replacement in each region. If you feel that you would like to be trained, or require further training, ask your designated regional anchor replacement co-ordinator, or contact Les Sykes C.N.C.C. secretary or Glenn Jones who will arrange for an in-depth training session in the Yorkshire Dales. The caves that have been re-bolted, have been re-bolted by the members of the caving clubs and the C.N.C.C. Technical Group. These cavers have been willing to give up their own caving time, to benefit other cavers. The C.N.C.C. would like to thank all the cavers who have undertaken the anchor re-placement work. The finance for the next phase of anchor re-placement will be part funded from the sales of the C.N.C.C. Technical Group rigging guide and the rigging cards, and part funded by the Council of Northern Caving Clubs.
