Abstract: A rope, a system and a method for measuring one or more properties of a rope. A property evaluation system for ropes can be deployed for a number of different applications including, but not limited to, moving lines, e.g., crane or winch and static lines, e.g., mooring lines, stays, etc., to evaluate physical properties of the ropes and, in some cases, to help evaluate structural health of the ropes. A sheave assembly (10) may transmit a signal into a rope (14) to measure at least one property of the rope. At least one sensor (25) may be coupled to or assembled in the rope to measure at least one property of the rope.

Abstract: A method for producing a synthetic tensile member having a precisely known and stable length. The invention also comprises equipment configured to carry out the method. A tensile member is prepared by attaching terminations to an assembly of synthetic filaments. The tensile member is then attached to a loading apparatus that subjects the tensile member to a pre-defined loading process. The tensile member is thereby conditioned to a stable length. The length is then measured and a length adjusting component is incorporated into the tensile member to create a precise and stabilized length that is configured for the tensile member's particular application.

Abstract: 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.

At the center of the hybrid rope 1, there is arranged a high strength synthetic fiber rope 3 formed by braiding multiple high strength synthetic fiber bundles 30 each composed of multiple high strength synthetic fiber filaments 31. Given that the pitch of braid of the high strength synthetic fiber bundles 30 is represented by “L” and the diameter of the high strength synthetic fiber rope 3 is represented by “d”, the pitch of braid “L” and the diameter “d” are adjusted such that the value L/d is equal to or higher than 6.7.
