Talurit Issues New Standard for Inspection Holes in Conical Ferrules

Pic for press releaseTalurit AB has recently been advising customers in Norway regarding the use of conical ferrules and the fact that these need to have an inspection hole. The reason for this is that a new version of the Norwegian standard called NORSOK R-002 was released in the autumn of 2012. This standard firmly points out that all ferrules used should be according to European Standard EN 13411-3. Now, both standards clearly states that where conical ferrules are used, the ferrule must have an inspection hole showing where the dead end is positioned inside the swaged ferrule. Given this fact, there is reason to believe that more and more end users in the lifting industry will demand that the products comply with valid standards.

The TALURITTM aluminum ferrules, type TKH correspond to the European standard for turn-back ferrules; EN 13411-3. The ferrules are extruded seamlessly over mandrel and the aluminum alloy is defined in detail according to EN 573-3. Furthermore is the requirement of an inspection hole covered by the TKH ferrule. The inspection hole is used to reveal the position of the dead end of the wire rope in the completed ferrule secured termination.

The TKH ferrule is thoroughly specified and very well defined for many different wire ropes, including high performance ropes. Non rotating ropes e.g. class 35(W)x7, following case 3 in the standard EN 13411-3 can be terminated with the TKH ferrule.
