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:
A rope and a method of constructing the rope. The rope may be of 12×12 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:
Die Erfindung betrifft ein Tragemittel (1) bestehend aus mindestens zwei Seilen (3a, 3b, 3c, 3d, 3e, 5a, 5b, 5c) zur Kraftaufnahme in Längsrichtung und einem Seilmantel (2), wobei die Seile in einer gemeinsamen Ebene im Seilmantel angeordnet sind, sodass der Seilmantel die Seile umschließt. Dabei weist zumindest ein Bereich des Tragemittels ein gegenüber anderen Bereichen des Tragemittels reduzierte Schneidbarkeit auf. Durch eine gezielte Reduzierung der Schneidbarkeit zumindest eines Bereichs des Tragemittels kann eine mutwillige oder vorsätzliche Beschädigung des Tragemittels mit einem Schneidwerkzeug minimiert oder sogar verhindert werden.
