Abstract:
A rope (210, 310) having a three-layered structure comprising a core layer, an inner layer and an outer layer, the core layer comprising one strand (225, 315), the inner layer comprising multiple strands (220) with an amount n and the outer layer comprising multiple strands (215) with an amount m, wherein n is an uneven number, and m is a number which has no common divisor with n, each strand is formed by multiple twisted metal filaments. By this structure fretting of the strands is reduced and the life time of the rope is improved. Also, the use of the rope in lifting application and an elevator system comprising such a rope are disclosed.
Abstract:
Le câble (31) multi-torons à deux couches de torons comprend: -une couche interne (CI) du câble (31) constituée d'un unique toron interne (TI), -une couche externe (CE) du câble (31) compacte et constituée de L>1 torons externes (TE). Chaque toron interne et externe (TI, TE) comprenant une couche interne et une couche externe de fils. La distance interfils D3' des fils de la couche externe de chaque toron externe (TE) est supérieure ou égale à 25 µm.

Abstract:
Provided are a steel cord for reinforcing rubber whose fatigue resistance is increased more than ever to enable achieving high durability that was not conventionally realized, and a pneumatic radial tire including the steel cord as a reinforcement member. In a steel cord for reinforcing rubber having a double-twist structure that includes a plurality of strands twisted together in the same direction with the same pitch and including a central structure and at least one outer layer, the central structure is composed of at least two strands being twisted around each other and each being composed of at least seven filaments being twisted together.; In a steel cord for reinforcing rubber including at least three core strands being twisted together and at least six sheath strands being twisted together around the core strands, the core strands and the sheath strands are twisted in the same direction.
Abstract:
The invention relates to a hybrid rope comprising a core element, a first and a second metallic closed layer surrounding said core element. The core element includes a bundle or construction of synthetic yarns. The first metallic closed layer includes a plurality of first wirelike members helically twisted together with the core element in a first direction. The second metallic closed layer includes a plurality of second wirelike members helically twisted together with said core element and said first metallic closed layer in a second direction. The cross-sectional area of the core element is larger than the total cross-sectional area of the first and second metallic closed layers.
