The Spirafix Team were asked to advise on a suitable anchor size to secure a climbing tower for use by the public. On site anchor testing was carried out using the Spirafix Test Rig and anchors were advised from the 75mm range.
3 x SF75-12-1100AC and 4 x SF75-12-1760AC anchors were used in conjunction with FS677 collared eyebolts. The anchors used are the biggest currently available from the Spirafix range - so a small number of large anchors. A hydraluic power installer was used plus hammer caps to protect the threaded head of the anchor. Installation and testing services were provided.
