Abstract:
A non-contact signal propagation 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. The system includes a first transducer for generating ultrasonic waves, a second transducer for receiving ultrasonic waves propagated transversely through and around the rope, and a processor executing computer readable code to determine acoustic propagation properties of the rope.
Abstract:
Cuerda (10) que comprende: una pluralidad de torones principales (12) que incluyen cada uno una pluralidad de fibras (16) formadas por un material de alta fricción, definiendo la pluralidad de torones principales una superficie exterior (18) y un canal central longitudinal (20) de la cuerda (10); y un torón secundario sin carga (14; 14a) que presenta una superficie exterior de torón y dispuesto dentro del canal central longitudinal (20) de la cuerda (10), incluyendo el torón secundario (14; 14a), al menos en la superficie exterior del torón, una pluralidad de fibras estructuralmente estables (22) formadas por un material no fluido de baja fricción, donde el material de alta fricción presenta un coeficiente de fricción contra sí mismo superior a un coeficiente de fricción del material no fluido de baja fricción contra el material de alta fricción, caracterizada por que cuando la cuerda (10) no se encuentra en tensión, el torón secundario (14; 14a) reside en un vacío relativamente grande definido por el canal central (20) de la cuerda (10), y donde cuando la cuerda (10) se encuentra en tensión, la pluralidad de torones principales (12) se mueven unos en relación con los otros para eliminar el vacío y entrar en contacto con el torón secundario (14; 14a), impidiendo el torón secundario (14; 14a) que los torones principales (12) entren en contacto unos con respecto a los otros en el canal central (20).
Abstract:
A rope and a method of constructing the rope. The rope may be of 12 x 12 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.

Abstract:
A tow kit is disclosed having a thimble slider engaged with a plurality of tethers. The thimble slider may have a generally C- shaped body with a back portion and opposing end portions. The thimble slider may also have a channel formed within outer surfaces of the back and opposing end portions, and an elongated separator connected to an inner surface of the back portion and extending in a direction generally orthogonal to the back portion to define two portions. A tether can engage the channel to equally distribute weight applied to the two ends of the tether. A sling can engage the inner surface of the back portion. At least one other tether can engage the sling.

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.
