Abstract (en)

[origin: EP2067893A2] The present invention refers to a metal rope with improved features, in particular having high ultimate tensile strength and a high number of sustainable fatigue cycles. The metal rope (10) according to the present invention consists of a plurality of strands (12) wound around a central core (14) and is characterised in that the central core (14) is made of a fibre spun from a liquid-crystal polymer. Preferably, this fibre spun from a liquid-crystal polymer is Vectran „¢ .
