Реферат: A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope comprises a core surrounded by multiple strands. The outer filaments of the core and the outer filaments of the strands are likely to contact one another during used. The outer steel filaments of the core have an average Vickers hardness that is at least 50 Vickers hardness numbers lower than that of the outer filaments of the strands. As the hardness of the outer filaments of the core is substantially lower than that of the outer filaments of the strands, those softer filaments will preferentially abrade away during use. In this way the core is sacrificed while preserving the integrity of the outer filaments of the strands. More preferably the core has a Vickers hardness that is lower than 600 HV. The hardness of the steel wire is a function of many factors such as carbon content, degree of cold deformation during drawing, heat treatment etc... Different variants of the idea are presented. The use of this 'sacrificial core' results in a higher residual breaking load after use. The coated steel wire rope comprises one steel wire rope and a polymer jacket surrounding the steel wire rope. The belt comprises several steel wire ropes arranged side-by-side and held together by the polymer jacket.
