Estimating the term…
A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope contains 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 use. 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. The use of this ‘sacrificial core’ results in a higher residual breaking load after use.
A steel wire rope for use in lifting applications, said steel wire rope comprising a core and multiple strands twisted around said core, said core and each one of said strands comprising an inner filament and outer steel filaments twisted together, said outer steel filaments being situated radially outward of said core and said strands, the steel of said steel filaments being a plain carbon steel that has been subjected to drawing,
