摘要

Suspension and traction system and elevator comprising at least one pulley and a suspension and traction element with at least one thread of a shape memory alloy. Suspension and traction system provided with at least one suspension and traction element and at least one pulley where the diameter of the pulley, øpulley, is less than or equal to 130 mm, the suspension element and traction comprises a load carrying section with at least one diameter wire øthread, of a shape memory alloy chosen from shape memory alloys whose characteristic temperature af lies below the ambient temperature, the value of the quotient øpulley/øthreads is between 50 and 2000. With this configuration life to fatigue is improved. (Machine-translation by Google Translate, not legally binding)
