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 load bearing assembly (100) for use in elevator system wherein the load bearing assembly (100) comprises at least one steel rope (102) and a jacket (110) surrounding this at least one steel rope (102). The jacket (110) comprises at least one layer of a thermoplastic elastomer comprising polymer particles (112). The polymer particles (112) have a molecular weight higher than 0.5*106 g/mol. The jacket (110) provides a coefficient of friction allowing sufficient traction between the load bearing assembly (100) and other components of the elevator system, such as the sheaves. Also disclosed is a corresponding method of making a load bearing member.
