Patent number: 11008703Abstract: 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.Type: GrantFiled: December 14, 2016Date of Patent: May 18, 2021Assignee: TEUFELBERGER FIBER ROPE GMBHInventors: Björn Ernst, Erich Rührnössl, Rudolf Kirth, Peter Baldinger, Robert Traxl, Gunter Kaiser

Patent number: 10808355Abstract: A high-strength fibre rope (1) comprising a rope core as well as a sheathing indicating optical wear, wherein the sheathing comprises a sheath layer (2) made up of textile subunits (3, 4) of a first hierarchy level. An outermost sheath layer (2) is provided, wherein textile subunits (3, 4) of said outermost sheath layer of the first hierarchy level differ from each other in terms of their textile structure, and/or an outermost sheath layer and a further sheath layer underneath said outermost sheath layer are provided, and wherein the textile subunits of the first hierarchy level of said outermost sheath layer differ in their textile structure from that of said further sheath layer. The textile subunits of a lowermost hierarchy level of the rope are neither dispersed in a resin matrix in the outermost sheath layer nor in the further sheath layer arranged underneath the outermost sheath layer.Type: GrantFiled: April 19, 2018Date of Patent: October 20, 2020Assignee: TEUFELBERGER FIBER ROPE GMBHInventors: Peter Baldinger, Robert Traxl, Gunter Kaiser, Rudolf Kirth, Björn Ernst, Erich Rührnössl
