  • Patent number: 11008703
    Abstract: The invention relates to a method for determining the replacement state of wear of a rope made of a textile fibre material, wherein, in the course of using the rope, the elongation of the rope is monitored over its entire length and the rope is discarded if the elongation of the rope over the entire length exceeds a predetermined maximum value (%). The method according to the invention is characterized in that also the local elongation of a discrete rope section is monitored and the rope is discarded if the local elongation of the rope section exceeds a predetermined maximum value (%), with the maximum value of the local elongation of the rope section being greater than the maximum value of the elongation of the rope over the entire length.
