Abstract
Method and arrangement in arranging an aluminium ferrule (2) to an eye (5) of a high strength steel wire rope (6) for fixation purposes, the ferrule (2) is pressed to securely fix said eye (5) and supposed to keep its diameter within a certain standard limit up to a minimum breaking load, dependant on the dimension of said wire rope (6). A ring (1) made from steel having an internally congruent shape but a smaller cross section than that of the ferrule (2) is arranged most close to said eye (5) before said ferrule (2) are together with the steel ring (1) is pressed in a conventional ferrule pressing tool to obtain a eye that is more stable with regard to its dimensions within said standard limit values.

A method of fixing an aluminum ferrule to an eye of a steel wire rope, comprising:
- arranging a steel ring having an internally congruent shape and a smaller cross-sectional area than that of the ferrule most close to the eye, and
- pressing the ferrule and the steel ring with a tool to securely fix the eye to the rope, whereby stability of dimensions of the eye is increased.
An arrangement for applying an aluminum ferrule to an eye of a steel wire rope, comprising a steel ring of a lesser cross-sectional area than the ferrule and applied to an inner part of the ferrule closest to the eye with the ferrule at a distance from the eye, wherein the distance equals a length of the steel ring from the eye.
